5th semester / MAIT students help
« Last post by techbits1616 on Today at 12:33:57 am »
hey everyone
in our college mait the 2 photocopy shops provide very good lecture notes for all subjects but they provide them very late :(
with the sessionals approaching i would request the seniors that if they have then please upload those notes of CSE 5th sem
please dont read and ignore plz :)

5th semester / mini project approval
« Last post by techbits1616 on August 18, 2017, 05:23:13 pm »
hi guyz i am a third year cse student in MAIT.
we are supposed to submit a mini project based on training done after 4th sem holidays.
i did a training in java and there we made a simple tic-tac-toe game.
i want to ask if it would be sufficient enough as a project? i dont want to submit something too tough as there would be viva and ppt too
ps: if anyone can also tell what are we supposed to add in the powerpoint ppt it would be great help :)

Projects / What is the difference between 3D printing and Additive Manufacturing?
« Last post by 3dtech on August 18, 2017, 02:39:25 pm »
Additive Manufacturing(AM) is the process of using additive technology to make quantities of production parts.  Doing this may include more technologies in addition to 3D printing in mumbai pune maharashtra india, such as milling, post processing, etc.





Essentially none. 3D printing is a type of additive manufacturing. I suppose it might be possible to come up with some process that isn't 3D printing, but is technically additive manufacturing, but it would be a stretch.

You could make the argument that the word "manufacturing" in additive manufacturing makes AM more of an industrial term and 3D printing less so, but it's a very subtle distinction.

Manufacturing methods can essentially be grouped into the following three categories:

    Subtractive - Material is successively removed from a solid block until the desired shape is reached
        Machining processes (turning, milling, drilling, etc.)
    Formative - Mechanical forces are applied to material to form it into the desired shape
        Shaping processes (bending, molding, pressing, etc.)
    Additive - Material is manipulated so that successive pieces of it combine to make the desired object
        3D-Printing processes (SLA, SLS, FDM, etc.)
The best example of this is interlocking parts: In materials like ABS plastic (Acylonitrile Butadiene Styrene), Polyamide, Alloy 910, Alumide, Nylon, PLA (Polylactic Acid)  ,  HIPS (High Impact Polystyrene), PVA (Polyvinyl Alcohol) or Rubberlike you can print interlocking parts, while in others like Gold, Silver, Bronze, or  SLA Resinthis is not possible. The reason behind this is not the material itself, but the technology that is used for printing each of these materials.

1. Ignoring Material Guidelines

Each and every 3d printing materials is different. Materials can be brittle or strong, flexible or solid, smooth or rough, heavy or light, and so on. This also means that an object should ideally be designed for a specific material. For example, if you know that you want to print your 3D model in Ceramics, there will be specific material-related design recommendations that you need to take into account such as supporting overhanging parts, strengthening elements that are sticking out, rounding off corners, etc.

2. Ignoring Printing Technology

Itís not only the basic chemical characteristics of our printing materials that are different, but also the technologies that are used for printing each of these materials.

The best example of this is interlocking parts: In materials like ABS plastic (Acylonitrile Butadiene Styrene), Polyamide, Alloy 910, Alumide, Nylon, PLA (Polylactic Acid)  ,  HIPS (High Impact Polystyrene), PVA (Polyvinyl Alcohol) or Rubberlike you can print interlocking parts, while in others like Gold, Silver, Bronze, or  SLA Resinthis is not possible. The reason behind this is not the material itself, but the technology that is used for printing each of these materials.

For ABS we use Fused Deposition Modeling (filament-based) with an extra nozzle and material for support, for Polyamide, Alumide, and Rubberlike we use Laser Sintering (powder-based), for precious metals we use lost wax casting (based on a 3D print in wax and a mold), and for Resin we use Stereolithography (liquid polymer-based).

Solution: Once again, our materials website holds all the answers. Checking our material pages before you start designing is always key. Also, keep in mind that with the use of different printers and printing technologies, the maximum printing sizes differ. You can find an overview about these here. 3d printing in jharkhand orissa,west bengal india



3. Ignoring Wall Thickness

4. Ignoring File Resolution
For 3D printing, the most common file format is STL (which stands for standard triangle language), which means that your design will be translated into triangles in a 3D space. Most 3D modeling software has the option to export your designs to an STL file and set the desired resolution.

Solution: In most 3D modeling software, when exporting a file you will be asked to define the tolerance for the export. This tolerance is defined as the maximum distance between the original shape and the STL mesh you are exporting. We advise choosing 0.01 mm for a good export. Exporting with a tolerance smaller than 0.01 mm does not make sense because the 3D printers cannot print at this level of detail. When exporting with a tolerance larger than 0.01 mm, triangles might become visible in the 3D print.

5. Ignoring Software Guidelines

Our community uses many different 3D modeling software packages. Some were designed for creating 3D prints, others are mostly used by 3D artists and their designs will require additional editing before they can offer a printable 3D model. For example, applying a wall thickness is automatic in some programs, while you must manually set it in others.
