Additive Manufacturing is digital engineering rather than merely a manufacturing tool. Examine its potential in realising Atmanirbhar Bharat, with reference to the National Strategy for Additive Manufacturing.

Additive Manufacturing (AM), or 3D printing, builds objects layer by layer from a digital file. It adds material instead of cutting it away [1]. Its value lies in design data, software and materials science. MeitY's National Strategy for Additive Manufacturing (NSAM), 2022 presents it as a pillar of Atmanirbhar Bharat [2].

Why AM is digital engineering

• Digital-first process chain: CAD, 3D scanning or AI design → STL file → slicing software → printing → post-processing. Without the digital instructions, the print fails [1].
• Convergence: AM brings together computing, electronics, design software and materials science. The AM-electronics supply chain is expected to grow from USD 18 bn to USD 112 bn [1].

Potential for Atmanirbhar Bharat under NSAM

• Import substitution: NSAM aims to add domestic value in machines, materials, software and components [3]. It targets 5% of the global AM market and about US$1 bn added to GDP [2].
• Skills and start-ups: 1,54,000+ people trained and 56 start-ups supported, with NSAM 2.0 now under way [1].
• Sector centres: medical devices at the AP MedTech Zone in Visakhapatnam, opto-electronics at C-MET Pune, agri-food at C-DAC Kolkata and renewables at IIT Mandi [3].
• Strategic and health uses: printing titanium and stainless steel for defence and aerospace; bone scaffolds and bio-ink tissue printing [1].

Gaps that limit this potential

• Outputs, not outcomes: the 3-year deadline for the targets has passed, but no figures on market share or GDP added have been published [1][2].
• Using vs making: there is no count of Indian-made printers or AM-grade powders. NITI Aayog warns that India's share of world manufacturing could fall from 3.5% to 2.5% by 2035 if industry does not adopt frontier technologies [4].
• Regulatory gaps: no rules yet on who owns design files, how cross-border files are taxed, or how printed implants are certified.

Way forward

• Build at home selectively (metal printers, powders, electronics-grade materials). Import ordinary polymer printers.
• Link NSAM 2.0 with the Electronics Component Manufacturing Scheme [5] and with NITI Aayog's goal of manufacturing at 25% of GDP by 2035 [4].
• Set dated outcome targets and AM-specific test standards.

AM turns design data into physical goods, so it carries India's digital strength into manufacturing. NSAM 2.0 must add Indian-made machines, materials and standards to its work on skills. Then AM can help make India a maker of technology, not just a user, in line with Atmanirbhar Bharat and SDG-9 (resilient industrialisation).
