Why in the News?

The PIB highlighted India’s progress in Additive Manufacturing (AM), or 3D printing, and the next phase of the National Strategy for Additive Manufacturing (NSAM 2.0).

News in Brief

• NSAM was launched by MeitY in February 2022 as India’s policy framework for additive manufacturing.
• More than 1.54 lakh people have been trained and 56 AM start-ups supported under the strategy.
• NSAM 2.0 aims to accelerate commercialization, IPR generation, digital integration, affordable machines and materials, and international cooperation.
• AM is being applied in space, defence, healthcare, electronics and construction, among other sectors.

What is Additive Manufacturing?

• Additive Manufacturing (AM) is a digital manufacturing process in which a physical object is created layer by layer from a digital design, rather than removing material from a larger block.
• It combines CAD, computing, electronics, AI, design software and materials science.

How does 3D printing work?

• The process begins with a digital/CAD design, which can be created digitally or obtained through 3D scanning or AI-assisted methods.
• The design is then converted into an STL file, which represents the 3D model through triangular surfaces.
• Next, slicing software divides the model into numerous horizontal layers and provides instructions for layer-by-layer printing.
• The 3D printer follows these instructions and deposits material successively to build the object.
• Finally, the layers are fused into a complete three-dimensional object, followed by post-processing to make the final product marketable.

Materials Used

• Thermoplastics: ABS, polycarbonate, PLA and PVA.
• Metals: Gold, silver, stainless steel, titanium and other alloys.
• Ceramics: Zirconia, alumina and tricalcium phosphate.
• Biomaterials: Silicon, calcium phosphate, zinc and bio-inks derived from stem cells.

Major Applications in India

Space and Aerospace

• AM enables production of lighter and complex components.
• In May 2024, Agnikul Cosmos demonstrated a single-piece, AM-printed semi-cryogenic rocket engine through Agnibaan SOrTeD.

Defence

• The Indian Army used AM for a two-storey dwelling unit in Ahmedabad, constructed in 12 weeks.
• Applications are also being extended to precast defence structures in Ladakh.
• NSAM supports AM-based maintenance, repair and overhaul (MRO) facilities.

Healthcare 

• AM can produce patient-specific implants and bone grafts.
• Indigenous bioceramic materials can help reduce dependence on imported medical technology.
• Research is also exploring bio-printed tissues and organs.

Electronics

• AM has been used to develop components such as batteries, antennas, varistors and capacitors.
• IISc has also demonstrated Photonic Integrated Circuit blocks using AM printing.

Construction

• The Kelvin 6K Pro has demonstrated construction of 2,500 sq ft homes in under 30 days using low-carbon geopolymer material.
• Potential benefits include:
  • Lower material and logistics costs
  • Lower carbon emissions
  • Faster construction
• Early applications indicate potential for 30% lower material and logistics costs and 90% lower emissions compared with cement-based construction.

National Strategy for Addictive Manufacturing (NSAM)

• NSAM provides a national framework for developing India’s 3D printing and additive manufacturing ecosystem.
• It brings together the Centre, States, industry and academia.

Development and Deployment Centres

• The government has established seven specialized centres for R&D, skilling and technology access.
• Centres cover areas such as medical devices, renewable energy, food processing, optoelectronics and optical computing chips.

NSAM 2.0

• The proposed next phase focuses on;
  • Accelerating IPR generation
  • Expanding the AM network through digital integration
  • Developing globally competitive technologies
  • Commercialization of indigenous technologies
  • Making machines and materials more affordable
  • Strengthening the AM-electronics value chain
  • Expanding start-ups
  • Supporting defence applications
  • SDG-oriented pilot projects
  • International cooperation on standards, joint research and technology partnerships.

Other Initiatives

Atal Tinkering Labs

• Schools are being exposed to 3D printing through Atal Tinkering Labs, which receive grants of ₹20 lakh and provide facilities such as 3D printers, robotics and IoT kits for students from Classes VI–XII.

National Additive Manufacturing Symposium (NAMS)

• NAMS provides a platform connecting policymakers, scientists, industry, start-ups and academia.
• The second edition was organized by MeitY on 13 March 2026 in New Delhi, with discussions on NSAM 2.0, defence applications and R&D centres.

ESTIC 2026

• The Emerging Science, Technology and Innovation Conclave (ESTIC-2026) will be held from 27–29 October 2026 at Bharat Mandapam, New Delhi.
• Its theme is “Creative Minds, Catalyzing Science, Empowering Technologies.”
• AM is among the emerging technologies highlighted at the event.

Significance and Challenges for India

• Additive Manufacturing strengthens Atmanirbhar Bharat b building indigenous manufacturing capabilities and reducing import dependence through domestic production of advanced components and medical devices.
• It promotes innovation by enabling rapid prototyping and the creation of complex designs, while also supporting strategic sectors such as defence and space.
• The technology can generate demand for specialized technical skills and employment, and where appropriately applied, can contribute to sustainability by reducing material wastage and emissions.
• It also supports the transition towards Industry 5.0 through digital, flexible and distributed manufacturing.

Challenges

• India faces challenges such as high costs of AM machines and materials, limited commercialization of indigenous technologies, skill gaps, and the need for stronger R&D and IPR generation.
• Other concerns include standardization, strengthening the AM- electronics value chain, improving industry-academia collaboration, and expanding international technology partnerships.

Way Forward and Conclusion

India should focus on commercializing indigenous AM technologies, making machines and materials affordable, strengthening R&D and IPR, developing skilled manpower, and improving industry-academia collaboration. Greater emphasis on standards, international partnerships and AM applications in strategic sectors can further strengthen the ecosystem.

With these measures, Additive Manufacturing can move beyond laboratories into factories, hospitals and strategic sectors, strengthening indigenous capabilities, reducing import dependence and creating skilled employment. It can thus become an important enabler of Atmanirbhar Bharat, Industry 5.0 and Viksit Bharat 2047.
