Tips and Tricks / How many raw materials can use in 3d printer?
« on: January 22, 2018, 11:38:06 am »
For getting a finished product it is very necessary to first construct a 3D image of the required model in the STL format, which is then sent to a 3D printer for a print out. There are four popular techniques that are used for printing your 3D models.



   Fused Deposition Modeling(FDM)
 
    Selective Laser Sintering (SLS)
    Poly jet/ink jet 3D printing
  Stereolithography (SLA)

Plastic:

At present the most commonly used printing technology is Fused Deposition Modeling (FDM). The FDM printers use thermoplastic filament which is heated till the melting point and then the molten plastic is placed layer by layer to form the model. These printers tend to use the following materials.

    Polylactic Acid (PLA)

It is probably the easiest to work as well as environment friendly. It is basically bio degradable plastic that has been derived from sources such as corn starch and sugar canes. This is available in soft and hard grades. With the increase in the popularity of PLA, this material is expected to overtake ABS in the near future.

    Polylactic acid (SOFT PLA)

It belongs to the softer version of the PLA that was discussed in the earlier point. It is rubbery and quite flexible but is available in limited colors and sources.

    Acrylonitrile butadiene styrene (ABS)/ Home printers

It is popularly known as Lego plastic and is considered to be the best material to work with as it is strong and very safe. It is made from spaghetti like filaments. It is available in a wide range of colors and is used for making of toys, bumper stickers etc.

    Polyvinyl Alcohol Plastic (PVA)

It is a type of plastic that is used as dissolvable support materials or is used for special applications. Makerbot and Shapeways are manufacturing lower-cost desktop printers like the Makerbot replicator 2; the material that these printers are using is PVA.

    Polycarbonate (PC)

It requires a high temperature nozzle design and is not widely used.

    Polymide (Nylon)

It is a strong and flexible material that allows a high level of detailing on the model. It is commonly called as white, strong & flexible / durable plastic / white plastic. It is a very strong and highly flexible plastic that is very fine and is basically a white granular powder. Due to these characteristics it is used in the interlocking and moving parts of the model.

Resins



Resins are used in 3D printing though the freedom of designing by this material is very limited. It is a bit rigid and delicate. Liquid polymer is cured with UV light to give the end product. The typical colors of this material are white, black and transparent. There are principally three different types of resins.

    High detail resins

Models that use this material are constructed from a photo polymeric liquid. This material is apt for models that require fine detailing and are small.

    Paintable resin

Models that have been constructed using this material have a very smooth surface and are beautifully painted.

    Transparent resin

Models are made of hardened liquid so the material is very strong, hard, stiff and water resistant by nature. This makes it an ideal material for 3D models. This material is suitable for models that require a smooth surface along with a transparent look.

castable resin



Other new materials:

TitanX : ade, high-performance and FFF/FDM-optimized ABS based engineering filament. TitanX is the evolution of ABS into a warp-free filament with unsurpassed mechanical properties and is extremely suitable for 3D printing large scale and high precision engineering objects.

ApolloX Material : ApolloX is a professional high-performance engineering filament, which is based on an uniquely industrial-grade modified ASA (Acrylonitrile Styrene Acrylate) compound.

PC - Plus  : Parts made with Polymaker PC show significantly improved mechanical strength compared to ABS and PLA under almost any deformation mode. Polymaker PC Plus shows good optical clarity, rendering parts with an attractive crystal shine!Polymaker PC offers outstanding fracture toughness that is simply unobtainable from other 3D printing materials of similar stiffness.

PCTPE :  PCTPE stands for "Plasticized Copolyamide TPE" or a substance co-polymer of very adaptable nylon and TPE (thermoplastic elastomer) . PCTPE has several unique features that allow any user to print a highly flexible part with the added durability of our nylon polymers.

Tips and Tricks / Which industry will benefit most from 3D printing?
« on: January 20, 2018, 11:10:16 am »
significantly benefiting from 3D printing:



    Aerospace: 3D printing is allowing for richer mechanisms to be built more simply without the need for welding that can be significantly lighter than existing approaches.

    Automotive: Similar to aerospace but the scale is different. Imagine if there is no long production lines but simply frames etc that come out the other end. how is 3d printing used in the automotive industry
    Biomedical: For things like prosthetics and orthotics where almost every object needs to be built based on individual needs, this will significantly reduce the turnaround time. Imagine every dentist having a 3D printer in their office for making orthotics, and every individual joint replacement being designed for that patient's needs. 3d printing in biomedical applications

    Design of all kinds: Whether it is architects constructing 3D models, industrial designers trying to get a "feel" for what an object looks like, the thinning of the barrier between bits and atoms is getting thinner.  3dprinting service in mumbai vadodara delhi nce india
Electronic field:

Printing metal in midair. 3D Printing and Laser Annealing of conductive metallic inks. This new method is opening up near limitless new potential applications in electronic and biomedical devices that rely on customized metallic architectures. 3d printing electronic components

The application of 3D printing is prevalent in the medical sector widely. Personalized prothetics, hearing aids, patient specific dentures are manufactured directly using 3D printing. 3D printed surgical guides are assisting surgeons to perform precise operations. Bio-printing technology is being used for imaging skin, tissue, bones and even human organs.

The aerospace and aviation sector was one of the first adopters of 3D printing technologies in product development and prototyping.

Many automotive companies are now considering the potential of 3D printing in achieving after sales functions concerning the production of replacement spare parts, on demand, instead of holding huge inventories.

3D printing in sync with 3D scanning and 3D modeling, has helped artists, architectures and sculptors to explore and reproduce exact replicas of an idea or structure of historical importance. Some visionary architects are conducting research on 3D printing as a direct construction method. Fashion industry is also indebted to the 3D printing technologyas they are being able to experiment and research newer trends in jewelries, shoes, hats, headpieces, and bags.

What is 3d printing?

While the term is broad, 3D printing generally means methods for constructing objects using additive technologies under computer control. This includes laser hardened resins, plastic extrusion, and other more exotic deposition technologies. It does not include milling machines and other CNC mechanisms as these remove material instead of adding it. It does not include carpentry or brick laying since these are not under computer control (though there is a 3D brick laying robot). 3d printing service mumbai  delhi vadodara india



Technology Types

Much like the early days of the automobile, there are many incompatible designs of 3D printers with hundreds of small companies jockeying for position. Still, we can break them down into just a few basic types: extrusion, fluid hardening, and exotic.

Fused Deposition Modeling (FDM)

Stereolithography(SLA)

So where do these two advantages help?

Custom: If you want something that no one else makes, or that no one else makes exactly how you want it, then custom printing is a win.

    Set and costume designers for TV & Film. If I need to build new phasers for my troop of five Klingons, a 3D printer is the tool to use.
    Architectural models
    Doll furniture
    Monogrammed / engraved items.


Locality: If the factory is far away in space or time then 3D printing your own item, even if physically inferior, is still a win. ex:

    An aircraft carrier canít carry parts for everything that could possibly break on such a large vessel. 3D printers solve that problem for things like gaskets and smaller plastic objects.

Future Developments


The 3D printing market is growing and changing rapidly. According to IDC: "The 3D printing market is set to emerge from niche to mainstream. The market will see tremendous unit and revenue growth from 2012 to 2017, with compound annual growth rates of 29 percent and 59 percent, respectivelyĒ. I think that is a bit optimistic, but clearly there is a lot of potential.

« on: January 18, 2018, 11:45:07 am »
talk about 3d printing we no longer talk about just printing small scale models for the fun of it, but we are talking about producing realistic prototypes and end use parts, for many different industries such as medical, consumer goods, manufacturing, aerospace and automotive, just to name a few. 3d printing service & prototyping in mumbai pune delhi ncr india




What is the Future of Additive Manufacturing?

The future of additive manufacturing looks bright. In the future, 3D printing will position itself more prominently in the manufacturing landscape. As costs continue to reduce and processes become more efficient, the possibilities for use-cases will expand considerably.

Successful organ transplant thanks to 3D printing

A three year old toddler benefited from innovative kidney transplant after suffering from heart failure, and subsequently kidney failure at just four weeks old. 3D replicas were made of the toddlers abdomen and of the kidney which was donated by her father, this aided the surgeons in the operation to plan how to fit an adult sized kidney into the body of a toddler.
This was the first operation of its kind, the 3D models that were used as an aid for the surgery ensured that this complex type of surgery was done in the safest way possible, the models allowed doctors to see intricate blood vessels and gave them the ability to plan precisely where the organs would be placed. A surgery that is this complex requires a significant amount of planning, and without the aid of 3D printing would have been much more difficult. This surgery had never been done before and is just one example of some incredible innovations in 3D printing in the medical field.

3d printing in Automotive Industry

Several companies in the automotive industry are hopping on the 3D printing bandwagon. For some, it was a form of technology already in use for creating prototypes. But now, itís beginning to play a bigger role. From building the frame of a car to creating molds for parts, advancements in 3D printing are sure to propel the automotive industry in new directions. Michelin has even developed its own 3D printer to create one-of-a-kind tire molds.

Physics education

Dr. Steven Sahyun, a physics professor, currently uses 3D printing as a way to create models used for learning. The students who benefit are visually disabled. Because of the limitations that visual impairments have on learning, he is using 3D printing to create models of objects, such as light bulbs, so that the students can better understand the physics concepts. Some of these will include braille lettering to make it easier to learn. benefits of 3d printing in education

Tips and Tricks / 3D Printing + IoT= The Future
« on: January 16, 2018, 04:55:26 pm »
Internet of Things aims at linking human behaviors to our day to day devices. Physical objects, people or animals will be provided unique identifiers and connected to a network embedded with electronics, sensors, software and internet connectivity, so that data can be exchanged between these without the need for a direct human-to-human or human-to-computer interaction, automating nearly every field of endeavor. The concept includes connecting human heart monitor implants, built-in automobile sensors packages, field operation tools for cops and firemen, biochips in farms and so on. In 5 years from now, the IoT will have 26 billion devices connected to it. prototyping service in delhi mumbai vadodara india




It is said that in 10 years, todayís silicon circuits will be replaced by plastic circuits. And 3D printing technologies will dominate such plastic printed electronics and circuits in IoT. Plastic printed transistors will become building blocks of wearable electronics and other IoT networks.

3D printing is already disrupting the current processes of design, prototyping, and manufacturing in almost every industry. As 3D printing gets adopted on a wider scale, many of the already invented products might have to be re-invented and we may have many more new products and things to learn about. For example, 3D printing has made many new and exciting geometries and shapes that were previously just imaginary. Our children might have formulas to learn that calculate area and volume of a shape we havenít seen or studied about.

Today, 3D printing or additive manufacturing (AM) is not a new word any more. Browsing through any 3d printing technology news website.

Another area where 3D printing may impact the electronics industry is the PCB board & drone electronics
. According to David ten Have, CEO of Ponoko a 3D printing company, printing the actual circuit boards are probably only 18 to 24 months away . With the accuracy and flexibility of 3D printing, this technology will offer potential cost savings and endless options of shape in the PCB industry. One day we may be able to place individual components and then print the PCB board accordingly to match the design , which will change the design of electronics completely. Experts are expecting to see major cost savings, environmental impacts and faster production cycles .
How does it work?

3D printers are being developed that allow to 3D print electronic circuits directly: similar to the Fused Deposition Modeling technology (FDM), the machines have to 3D printing nozzles, one for the support material (typically plastic), and one for the circuit, using a conductive ink.

3D printing for the production and prototyping of casings for electronic devices: itís already broadly used!

3D printing is already used fairly broadly by the electronics industry, for everything that goes around the electronic components. Thanks to the fact that it allows mass customization, cheap iterations and adaptive design, 3D printing is often used to create cases for electronic devices.  3d printed electronics enclosure

SLA Resins   

General Purpose Resins
To start, there are a number of firms producing 3D printing resins for desktop machines. Though many 3D printer manufacturers sell their proprietary materials, several generic brands have taken to making their own varieties for these systems, including MadeSolid, MakerJuice and Spot-A Materials.


Tough Resins
Typically photopolymer resins used for 3D printing on desktop machines are somewhat fragile, leaving those delicate details susceptible to snapping and cracking. For this reason, the technology has been used more frequently for aesthetic purposes, such as artistic models and visual prototypes. To address these issues, numerous companies have begun producing tougher and more durable resins.

Castable Resins


Casting has long been a process supported by photopolymerization technologies, with industrial manufacturers often marketing SLA and DLP machines to the dental and jewelry markets for the ability to fabricate parts that can be cast as metal. Naturally, producers of resins for desktop machines began with low-cost casting resins.



Flexible Resins

There are a limited number of manufacturers of flexible resins, including Formlabs, FSL3D and Spot-A Materials, all of which make a material for printing rubbery parts. This is ideal for prototyping elastic products, such as water bottles, handles and grips. Careful not to stretch too much or these components might tear!

High-Temp Resins
Formlabs, however, is so far the only low-cost manufacturer to produce a resin that can withstand high temperatures. The material has a heat deflection temperature (HDT) of 289 įC (552 įF) at a loading of 0.45 MPa , which is not just good for desktop SLA, but for all 3D printing photopolymers, including industrial systems. It can therefore be used for such applications as producing injection molding tools, testing channels designed for hot air or fluids and creating tools for thermoforming and casting.

Ceramic Resins
Tethon3D is a materials company focused on ceramics for 3D printing, first creating its own ceramics material for 3D Systems' binder jetting 3D printers. The Nebraska-based company then launched a crowdfunding campaign for a resin called Porcelite.

Open-Source Resins

It's a bit unclear how many folks are purchasing or building Autodesk's open-source Ember 3D printer, but the software company deserves props for releasing the complete designs for its DLP machine. More than that, Autodesk actually opened up the recipe for its photopolymer resin as well. The company's standard clear resin can be developed at home or in a lab or modified to produce new materials.

Tips and Tricks / SLA vs FDM: Choosing the Right 3D Printing Technology
« on: January 10, 2018, 11:24:14 am »
Of these various technologies, 5 3d printing technologies became very popular. These are FDM, SLA, SLS, PJP, DLP. In this article we shall discuss more about FDM and SLA technologies and also the difference between these two technologies.  3d printing service in chennai,bengaluru,kerala,tamilnadu,karnataka,india



different applications of 3d printing


Fused Deposition Modeling (FDM)

FDM stands for fused deposition modeling. In FDM technology, material is deposited in layers to create a 3D printed object. A plastic filament is fed through hot extrusion head. In the extrusion head, the filament gets melted. This melted filament will be deposited by drawing plastic lines on top of previous layers. FDM printing is one of the most widely used forms of 3D printing as of date. This can be primarily attributed to the fact that the FDM printer comes at a low price point. The bonding force of FDM type printers isnít very strong. This leads to layer separation of resulting prints compromising on the resolution and surface smoothness. Also, if the diameter of extruded plastic line gets smaller, the printing speed will come down drastically.

Here is a beautiful time lapse video on give an overview on FDM technology
Advantages of FDM technology

FDM 3D printing a good option for those wanting to test a part's functionality and use prior to large-scale injection mold manufacturing.

Avilable Materials : PC, Ninjaflex, PLA, CarbonfiberPLA



Best Use Case

FDM can be used for one-off, single use low cost, non structural parts


Stereolithography (SLA)

SLA stands for stereolithography. In Stereolithography, UV light pattern is used to cure full layer of resin. The photo polymers are cured layer by layer to create the final object. SLA produces higher resolution objects and is more accurate than FDM as the resolution is primarily determined from the optical spot size which is very small. Also, much less force is applied in SLA than in FDM during layer formation and so the surface finish is much smoother and objects printed using SLA look much more professional than FDM printed objects.

Advantages of SLA technology

Good quality finish, mechanical strength

SLA Resins:  castable resin, flexible resin, hard regid resin

Best Use Case

SLA can be used when parts have intricate details or need a very smooth surface finish.

General Talk / 3D Printing: How It Works & What it is Used For
« on: January 09, 2018, 12:10:57 pm »
3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.





How Does 3D Printing Work?

It all starts with the creation of a 3D model in your computer. This digital design is for instance a CAD (Computer Aided Design) file. A 3D model is either created from the ground up with 3D modeling software or based on data generated with a 3D scanner. With a 3D scanner youíre able to create a digital copy of an object.

The 3D printing industry encompasses many forms of technologies and materials. When most people think of 3D printing they are thinking of a simple desktop FDM printer but thatís not the entire picture. 3D printing can be divided into metal, fabrics, bio and a whole host of other industries. For this reason, itís important to see it as a cluster of diverse industries with a myriad of different applications.

Education

Educators and students have long been using 3D printers in the classroom. 3D printing enables students to materialize their ideas in a fast and affordable way.

Rapid Prototyping

Manufacturers have long used 3D printers in their design process to create prototypes. Using 3D printers for these purposes is called rapid prototyping.

3d printing in automotive industry

Car manufacturers, restorers and repairers have been employing 3D printing for a long time. Automotive industry experts only expect the use of AM technologies to grow in the coming years. Companies are using it to produce not just parts, but tools and interior elements.

Aerospace

If you want to see 3D printing applied in the wildest ways imaginable, look no further than the aerospace industry. From materials to concept printers they are doing some of the most interesting, cutting edge research in the entire field, all for the purpose of making interstellar exploration more habitable

3d printing in architecture industry

Can you print buildings? Ė you sure can. There are not many of them, but companies like Apis Cor are producing fascinating results. The company claims it can print a house within 24 hours. Currently, it lends out its machinery to various other firms.

Product Design

Even though prototyping is still the number one use of printers, there are many instances of companies producing end user products with 3D printers.


Medical

The outlook for medical use of 3D printing is evolving at an extremely rapid pace as specialists are beginning to utilize 3D printing in more advanced ways. Patients around the world are experiencing improved quality of care through 3D printed implants and prosthetics never before seen. Even 3D printing pens are helping out in orthopaedic surgery.

Fashion

3d printed fashion collection has been on the periphery of the fashion world. Aspiring designers have long been trying to leverage its potential.

Types of 3D Printing Technologies and Processes

There are several ways to 3D print. All these technologies are additive, differing mainly in the way layers are build to create an object.

Stereolithography (SLA)

The most commonly used technology in this processes is Stereolithography (SLA). This technology employs a vat of liquid ultraviolet curable photopolymer resin and an ultraviolet laser to build the objectís layers one at a time. For each layer, the laser beam traces a cross-section of the part pattern on the surface of the liquid resin

Fused Deposition Modeling (FDM)

The FDM technology works using a plastic filament or metal wire which is unwound from a coil and supplying material to an extrusion nozzle which can turn the flow on and off. The nozzle is heated to melt the material and can be moved in both horizontal and vertical directions by a numerically controlled mechanism, directly controlled by a computer-aided manufacturing (CAM) software package.

What materials does a 3D printer use?

3D printers use an array of different materials including plastics, resins, metals, ceramics and much more. Here is a little break down of some of the materials that you can use:

ABS or PLA plastic Ė any cheap plastic object that you buy is more than likely made out of ABS plastic Ė as it has become the standard for most things. ABS is more flexible and durable than PLA which is why it is commonly used for 3D printing. Both ABS and PLA are the cheapest raw materials that you can use in a 3D printer. To change colours you will need to switch out one colour of filament for another one.

Nylon Ė this is quite similar to printing with ABS plastic apart from the fact that the material is white powder. Nylon printing makes the final product very flexible and offers alternatives to inexpensive printers. You can polish objects printed in Nylon, dye them or paint them different colours. It is the best method for printing textiles.   

Powder materials Ė this is for the most sophisticated of 3D printers. It fuses together heat from the laser and can work with almost any material. If something can be turned into powder, there is usually a way to print with it. The results range from things such as copper, iron, steel, gold and ceramics. The finished product will require not welding or machining as it is usually very strong.

First of all, what is 3D printing? It's the process by which three-dimensional digital models are made into physical objects using a 3D printer. Working in tandem with computer software, the 3D printer reads a digital .STS file on a computer and then uses a filament or a resin to render the digital representation in tangible material, layer by layer.

3D printers employ a variety of materials, including plastics and polymers, steel, titanium, gold, and ceramic. This versatility means 3D printed models can be used for everything from artistic sculptures to airplane components. Some 3D printers can even print proteins and chemicals, enabling the devices to create foods and medicines.

 Applications for 3D printers
Prototyping

One of the oldest uses for 3D printers is the quick and efficient creation of prototypes. Since the printers were invented in 1983, companies have employed 3D printing in order to get a workable model of their desired end product, either to test the concept or present it to future investors. 3d printing service in chennai,bengaluru,kolkata,lucknow,kanpur,karnataka india

"Before we called it 3D printing, it was called rapid prototyping," Greg Paulsen, director of project engineering for third-party manufacturer Xometry, said. "It used to be seen as a way to get close enough to a functional model."

 Low-volume manufacturing

Though 3D printers can be slow-moving, they're adept at fulfilling low-volume production needs. Much like with prototyping, if an entrepreneur is ready to launch a new product and isn't certain of the demand, he or she can print up a small amount to test the waters. Low-volume production is also common when it comes to medical devices, for example, as manufacturers create, test and redesign their products for optimization.

 Mechanical parts

Another beneficial use for 3D printers in is the creation of mechanical parts, either for sale in large industries or for personal repairs. Many products of 3D printing aren't sold directly to consumers, but are created by companies (or third-party contractors) as components in a larger project. One example is GE Aviation's 3D printed fuel nozzle, which will be added to the company's CFM LEAP airplane engines.

biomedical 3d printing

One particularly exciting aspect of 3D printing is the ability to print biomedical devices tailored specifically to individuals. For example, some companies are developing 3D printed, custom prosthetics for amputees; these prosthetics are designed to be far more comfortable for the user.

 Design

When engineers design a product, they must keep in mind the limitations of the production process. 3D printers are capable of creating parts that would previously not be achievable using traditional manufacturing techniques. This opens up an entirely new world in the design phase, which can lead to better, more efficient 3d printed  products and component parts.

« on: January 02, 2018, 11:55:47 am »
3D Filament Defined

3D filaments are special types of plastics called thermoplastics. Once heated to the right temperature, thermoplastics become flexible. Itís this pliability that allows the printer to sculpt the filament to create your shapes before it cools down. In 2017, the two common types of 3D filaments are:



    ABS (Acrylonitrile Butadiene Styrene)
    PLA (Polylactic Acid)

1. ABS 3D Filament

PRICE STARTING FROM: $20 for 1.75 mm, 1kg spool

ABS is popular for good reasons. Itís tough, and has impact-resistant properties. Itís this strength and moderate flexibility that makes it such a great choice for printing in 3D. Itís also easy to extrude from the printerís nozzles, which makes it an easy material to work with. 3d printing service in mumbai pune,delhi india

2. PLA 3D Filament

PRICE STARTING FROM: $20 for 1.75 mm, 1kg spool

PLA (Poly Lactic Acid) is popular for amateurs and professionals alike. Itís a special type of thermoplastic made from organic materials, namely cornstarch and sugarcane. The main benefits of PLA are that itís safer and easier to use, and with no toxic fumes to worry about. Some users even find the sweet smell of the sugar-based filament pleasant. Compared to ABS, PLA produces 3D parts which are more aesthetically pleasing. This finish is thanks to its unique sheen and smooth appearance.

PLA has wide-ranging uses. At the professional level, PLA filament uses include medical suturing (stitching). We can also see PLA used for various surgical implants, including surgically implanted pins, rods, screws, and mesh. The applications work thanks to the materialís degradable properties. All the aforementioned 3D printed parts break down in the human body.


3. T-glase Filament

Applications:

PETT is another of those FDA-approved polymers. This makes it safe for use with food. The majority of PETT applications are various food containers and other kitchen utensils.

4. Nylon Filament
Nylon filament, also called polyamide, is another popular choice. This is a synthetic polymer thatís stronger and more durable than ABS and PLAóand cost-effective. Itís also flexible, light, wear-resistant, and less brittle than both ABS and PLA. There are different kinds of nylon filament available, and what you choose will depend on which one suits your budget and needs. The difference between them is in the filamentís layer bonding abilities, tensile strength, and water absorption. You can also choose nylon filament that has a translucent or opaque finish and reduced shrinkage.

Nylon print temperature range: 210įC Ė 250įC (high)
Applications

Nylon filament is great to use in a whole variety of applications thanks to its strength, flexible properties, and durability. Itís particularly suited for various consumer products, tools, mechanical components, machine parts, structural parts, containers, and a much more.

5. PVA Filament

Applications

In 3D printing, PVA works as a support material (see above). Aside from 3D printing, PVA has many other applications. We can find it used as a thickener in paper adhesives, in personal hygiene products, as a mold-release agent, kidís putty, and freshwater fishing products, to name a few.

6. HIPS Filament

High Impact Polystyrene, HIPS for short, is a bright, white colored 3D biodegradable material. Itís safe to use, meaning it has no harmful effects for users who are in close contact with the filament. Itís safe with pets too.

Applications

For 3D printing, the most common application for HIPS is as a support material for other filaments (see above). Aside from 3D printing, other industries use HIPS because itís a strong, ridged plastic that they can manipulate to suit their needs. The food industry uses it widely for packaging. Other uses include medicinal trays, signs, all kinds of kidís toys, and much more.

7. Magnetic Iron PLA Filament
As the name suggests, magnetic iron PLA filament has magnetic properties. This unique filament is PLA material infused with a powdered iron. Itís these iron particles that give the 3D parts their grainy gunmetal type finish

Applications

If you want to produce custom made fridge magnets, and other such novelties, magnetic iron PLA is for you. For home users, this is pretty much a novelty material. For more serious uses, magnetic filament is useful for making various DIY projects, sensors, and educational tools, etc.

8. Conductive PLA

Anyone wanting to broaden their horizons in 3D printing may want to look to conductive PLA 3D printer filament. Itís a special type of 3D material that includes a conductive carbon particulate. Without getting too technical, this means the material is able to print low-voltage electrical circuits. These will typically include sensors and light-emitting diodes (LEDs).

Applications

Conductive PLA filament is perfect for open-source electronics platform Arduino projects. If you want to create circuits, LEDs, sensors, and various low-voltage projects, youíll want explore this filament.

9. Carbon Fiber 3D Printer Filament
Carbon Fiber PLA is an impressive 3D filament. The material contains tiny strands of carbon fiber which results in a material that has an excellent structure. Itís also rigid and has superior layer adhesion. Carbon Fiber PLA shares similar properties with standard PLA but itís stiffer.

Engineering entrance / A 3D printed future: surprising print
« on: December 04, 2017, 11:55:47 am »
From artificial prosthetics to very real human kidneys to filigree skull sculptures ó the number and variety of applications for this technology are growing, layer by printed layer.

However, there is still a ways to go. Before we can have Bastianís jumbo jet, we need the giant 3D printer to print it. Bastian reminds us of the importance of having a vision. He says, ďWe cannot predict the future. We can only create a vision of what it might be.Ē 3d printing vadodara,baroda,ahmedabad,surat,rajkot,bhavnagar,vapi gujarat india



Here, more revolutionary visions of our 3D printed future:

1. Rocket parts- 3d printed automotive parts. NASA is working on the largest rocket ever constructed that is projected to take humans to Mars by 2030. Bypassing traditional processes for building rocket parts, which require welding of seams, creating a single seamless 3D printed piece means less chance for leakage. It also cuts down the cost of manufacturing by almost half. Recently, NASA tested 3D-printed rocket engine injectors in hot-fire tests, exposing them to extreme temperatures and pressures. They passed with flying colors.

2. 3d printing in architecture industry. Designer Alastair Parvain explores the idea of regular people being able to print and construct their own homes. In his TED Talk, he talks about WikiHouse, an open-source construction kit thatís a library of 3D models and cutting files that will allow anyone using a CNC machine and plywood, to ďprintĒ out the parts for their own house. Meanwhile in Amsterdam, construction of a 6-meter tall printer called the KamerMaker (Dutch for room-maker) has already begun for printing components of a house.

3. Liquid metal parts. At North Carolina State University, researchers developed a metal alloy that remains at a liquid state at room temperature. They then used a syringe to arrange the droplets into a vertical chain-like structure. The next step, now, is to create a 3D printer for the purpose of printing this liquid metal. If the technology is harnessed, it would allow for the creation of bendy electronics, and revolutionize the electronics manufacturing process.

4. Bionic ear and jaw bone.  Right now, the potential for 3D printing in the medical sphere is incredible. Last year, an 83-year-old Belgian woman received the first 3D printed jaw bone, a transplant that was tailored specifically for her facial structure. A bionic ear was printed from a concoction of calf cells and hydrogel and antennae made from nanoparticles. The first version allowed hearing at a superhuman range, powerful enough to pick up radio waves.

5. 3d printing fashion future. Designers are already experimenting with 3D-printed materials in creative and innovative ways. The cheaper cost of manufacturing would certainly have an impact on the current system of mass production. Silk is already being experimented with. MIT researchers have used 6,500 silkworms to 3D-print this ethereal silk dome-shaped pavilion covering.


6. A Moon base. Architecture firm Foster + Partners have paired with The European Space Agency to investigate the possibility of a 3D printed moon habitat. The material used in the printing process would be moon dust and soil that would be layered to form a building block, not unlike concrete. This method would save us from the challenge of transporting raw building materials.

Retail

Nike and Adidas are already experimenting with the use of 3D printers to create shoes. It wonít be long until other retailers will be able to jump on this new opportunity and fill the market with 3D printed clothes, shoes, hats, purses, etc. 3d printing services in Orissa, Jharkhand,West Bengal,Bihar,andhrapradesh,india

Architecture

Same for an architect, who can use the computer to design a complete house and then print it scaled in 3D for the customer to evaluate. He would have a real 3D model that their customers could hold and look at from all directions. Mostly, they would need some handwork and proper craft skills to make it but this way, the computer will just make it for them. 3d printing in architecture industry



So, the future for 3D printing will mostly be rapid prototyping so models can be made before they continue to work on the product and make it final. The 3D printer could also be used to make molds that would later be used for mass production.

Projects / Introduction to FDM 3D Printing
« on: October 03, 2017, 02:21:12 pm »
Fused Deposition Modeling (FDM), or Fused Filament Fabrication (FFF), is an additive manufacturing process that belongs to the material extrusion family. In FDM, an object is built by selectively depositing melted material in a pre-determined path layer-by-layer. The materials used are thermoplastic polymers and come in a filament form.3d printing services vapi gujarat



FDM is the most widely used 3D printing technology: it represents the largest installed base of 3D printers globally and is often the first technology people are exposed to. In this article, the basic principles and the key aspects of the technology are presented. A designer should keep in mind the capabilities and limitations of the technology when fabricating a part with FDM, as this will help him achieve the best result. 3d printing services in Jammu and Kashmir, Himachal Pradesh, Punjab, Uttarakhand , Uttar Pradesh and Haryana,chandigarth,kochi,bhopal,visakhapatnam,india

How does FDM work?

Here is how the FDM fabrication process works:

A spool of thermoplastic filament is first loaded into the printer. Once the nozzle has reached the desired temperature, the filament is fed to the extrusion head and in the nozzle where it melts.

The extrusion head is attached to a 3-axis system that allows it to move in the X, Y and Z directions. The melted material is extruded in thin strands and is deposited layer-by-layer in predetermined locations, where it cools and solidifies. Sometimes the cooling of the material is accelerated through the use of cooling fans attached on the extrusion head.

Common FDM Materials



    Polylactic Acid (PLA)

It is probably the easiest to work as well as environment friendly. It is basically bio degradable plastic that has been derived from sources such as corn starch and sugar canes. This is available in soft and hard grades. With the increase in the popularity of PLA, this material is expected to overtake ABS in the near future.

    Polylactic acid (SOFT PLA)

It belongs to the softer version of the PLA that was discussed in the earlier point. It is rubbery and quite flexible but is available in limited colors and sources.

    Acrylonitrile butadiene styrene (ABS)/ Home printers

It is popularly known as Lego plastic and is considered to be the best material to work with as it is strong and very safe. It is made from spaghetti like filaments. It is available in a wide range of colors and is used for making of toys, bumper stickers etc.

    Polyvinyl Alcohol Plastic (PVA)

It is a type of plastic that is used as dissolvable support materials or is used for special applications. Makerbot and Shapeways are manufacturing lower-cost desktop printers like the Makerbot replicator 2; the material that these printers are using is PVA.

    Polycarbonate (PC)
t requires a high temperature nozzle design and is not widely used.

Alloy 910

It requires a high temperature nozzle design and is not widely used.
Powders:

The higher end printers use powder based materials for the construction of 3D models. The various powders available by which printing can be done are:

   Polymide (Nylon)

It is a strong and flexible material that allows a high level of detailing on the model. It is commonly called as white, strong & flexible / durable plastic / white plastic. It is a very strong and highly flexible plastic that is very fine and is basically a white granular powder. Due to these characteristics it is used in the interlocking and moving parts of the model.


Post Processing

FDM parts can be finished to a very high standard using various post processing methods, such as sanding and polishing, priming and painting, cold welding, vapor smoothing, epoxy coating and metal plating. An extensive article on post processing of FDM parts can be found here
Benefits & Limitations of FDM

The key advantages and disadvantages of the technology are summarised below:

    FDM is the most cost-effective way of producing custom thermoplastic parts and prototypes.
    The lead times of FDM are short (as fast as next-day-delivery), due to the high availability of the technology.
    A wide range of thermoplastic materials is available, suitable for both prototyping and some non-commercial functional applications.
