Tips and Tricks / How many raw materials can use in 3d printer?
« Last post by 3dtech on Today at 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.

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?
« Last post by 3dtech 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.

General Talk / How do professional packers and movers help?
« Last post by packers on January 19, 2018, 03:05:34 pm »


If you are using packers and movers for your move, it will save you a lot of time - and time is money - right?  I cannot tell you how many people intend on packing themselves only to call their moving company a few nights ( or the night before ) only to ask for help.  For an average 2 bedroom condo, it should take 2 professional movers approximately 5 hours MAX to pack up.  If you haven't hired professional movers and packers before, you may thing I am exaggerating.  The truth is, movers are trained to come in a swiftly and carefully pack - they are not there to reorganize and they don't have emotional bonds with any of the pieces they are packing.  I always tell people to hire a moving company than move an pack for these reasons: packers and movers vadodara

1. It will save you a bundle of time.

2.  Movers and Packers will only cover ( as in insurance ) what they pack.  For example, if you pack your own waterford crystal - they will not cover it.  It's in the bill of lading.

3.  High Quality Materials - If you hire one of the best choice movers and packers they will have access to high quality materials - bubble wrap, packing paper, boxes, pads that cost the average person a fortune.  Home Depot boxes will do for books and linens but for lamps, TVs, pictures, china - heavy duty boxes are suggested. local movers and packers in vadodara



Other really important things to know about packers and movers:

1. Van lines charge per box packed, private companies will charge labor plus materials ( with a huge discount ).  You don't want a van line packing your boxes - they have been known to put four towels in a 4.5 linen box in 3 minutes and they charge approximately $30/linen box!  Private movers and packers charge about $3/box and labor at $40/hour. Also, there are a lot of private movers that have free packing material delivery so you can get the easy stuff done on  your own.  Seek them.

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.

Glossary
