Fascinating World of Additive Manufacturing / 3D Printing

3D Printing or Additive Manufacturing is a result of digitization and it has become widespread in recent years so much so that many refer to it as 3rd industrial revolution. It allows users to make things that would be almost impossible to make in a traditional machining environment. 3DP as a technology has already started to revolutionize sectors like medicine, education, automation and even aerospace industry.

Vel Tech Dr.RR & Dr.SR Deemed to be University has been integrating 3DP into UG/PG programs for past few years and the results of this effort are seen in many ways. 3DP machines work directly from CAD data, so students can make parts with exciting design features and shapes, without entering workshop. There are many methods to do 3D printing, but all have one thing in common: instead of cutting, drilling and milling objects, as a conventional factory does, to remove material and arrive at the required shape – a 3D printer starts with nothing and adds stuff to it layer by layer.

How do they work? Some work by squeezing the molten plastic through a small hole and depositing on a plate; exposing liquid araldite like material to laser in a precise way and solidifying it or fusing the metal particles together using a binder. Based on the process that you use we may call it as Fused Deposition Modelling or Stereo lithography or Powder Jet Binding.

In Vel Tech we have five 3D printers that are used to help students to make parts for aeronautical, mechanical, automotive, electronics and bio engineering projects. What can students do? They can bring CAD data and convert them into physical parts and test or make innovative designs and explore entrepreneurship ideas or custom develop the part, like a casing for a mobile phone and be the author of design. Student from any branch can use 3DP and great design oriented projects.
