In the domain of manufacturing technology, it is rare to come across innovations that have the ability to transform the industry, enabling products to be developed faster, cost-effectively and opening a doorway for seamless creativity. With the use of Additive Manufacturing (AM) or 3D printing technologies, several intricate and complex shapes which cannot be Manufactured through conventional subtractive manufacturing processes can be manufactured with great precision. Similar to the advent of CNC machining, automated lines software tools such as CAD/CAM/CAE, additive technologies will play a pivotal role in reshaping production. What is central to 3D printing is the use of intensive energy to integrate metallic powders, plastics, sand etc. to create highly complex components that stand out from the designs of today. Contrary to other technologies, AM concepts are being employed in almost every segment including aerospace, defence, medical, energy, automotive, general engineering, toolings, food, life style products etc.

Why Additive Manufacturing?

3D Printing or Additive manufacturing is a novel method of manufacturing parts directly from digital model by using layer by layer material build-up approach.

This tool-less manufacturing method can produce fully dense metallic parts in short time, with high precision. It is a transformative approach to industrial production that enables the creation of lighter, stronger parts and systems.

Besides, this technology is environment-friendly and energy efficient when compared to conventional methods.

AM has already forayed into Aerospace, Defence, General Engineering and Medical sectors and is trying to establish itself in other sectors. It complements conventional subtractive manufacturing such as milling, drilling & turning. Most parts after printing will need to be post-processed on metal cutting machine tool to finish it.

Some of the key advantages of AM are:

  • Unlimited Design Freedom: AM makes possible the manufacturing of any design regardless of its design complexity. It also allows the production of integrated components.
  • Product Development: AM does not need specific tooling or casting. Any design may be produced in a short period of time under a cost-effective perspective.
  • Flexible Supply Chains: Production by AM does not require any special tooling or casting, Hence, shifting the production to a completely different object is easy and immediate.
  • Light Weighting: AM enables the construction and manufacturing of highly stable light weight structures that can’t be produced using any conventional technologies.
  • Access to Complex Geometries: Internal channels for conformal cooling, hidden features, thin walls and fine meshes are only possible in additive manufacturing.
  • Low Scrap Rate and Wastage: AM is subjected to very minimum scrap rate and wastages compared to conventional methodologies.
