GS Paper - 3 (3D Printing)

The government aims to capture five per cent of the global market share in additive manufacturing or 3D printing with expectations to add nearly USD 2-3 billion to the GDP in the next 2-3 years, Union Minister Ashwini Vaishnaw said.

What

  1. Under the National Strategy on Additive Manufacturing, the government plans to create 50 India-specific technologies for material, machine, process and software to make India a 3D-printed design and manufacturing hub.
  2. The value of precision electronics is high. It is estimated to contribute USD 2-3 billion in GDP coming 2-3 years.
  3. The strategy aims to create 100 new start-up, 500 additive manufacturing products and 50 Indian additive manufacturing technologies on material, machine, process and software.
  4. The 3D printing has a lot of scope in making artificial limbs, stents, dental crowns, parts of automobile and consumer goods, among others.
  5. In December 2020, the IT ministry was readying a national policy on promoting 3D printing on an industrial scale and helping domestic companies “overcome technical and economic barriers” so that they can build supportive and ancillary facilities for world leaders in the technology, such as the US and China.

Flashback

  1. Additive manufacturing (AM) or additive layer manufacturing (ALM) is the industrial production name for 3D printing, a computer controlled process that creates three dimensional objects by depositing materials, usually in layers.
  2. Using computer aided design (CAD) or 3D object scanners, additive manufacturing allows for the creation of objects with precise geometric shapes.
  3. These are built layer by layer, as with a 3D printing process, which is in contrast to traditional manufacturing that often requires machining or other techniques to remove surplus material.
