Bangalore · Sovereign Metal AM
The manufacturing infrastructure behind .
KRITTVA DNA is building India's first fully integrated, aerospace-grade metal additive manufacturing platform: print, heat-treat, machine, test and qualify under one certified roof, for the Defence, Nuclear, Aerospace and Medical programmes the nation depends on.
01 · Why additive
Three ways to make a part. Additive does what the others can't.
Every manufacturing method trades something away. For the geometries that define modern propulsion, thermal and structural hardware, only one builds what the design actually demands.
Formative
Shaped by force or mouldCasting, forging and moulding.
- Low unit cost at high volume
- Good mechanical properties
- Heavy tooling cost, long lead times
- Design locked; no internal complexity
Additive
Built layer by layerMetal AM: Laser Powder Bed Fusion.
- Internal channels, lattices, part consolidation
- No tooling; complexity is nearly free
- Demands post-processing and certification
- Most stall at that barrier. We clear it
02 · One certified roof
From qualified powder to flight-ready part, with no handoffs.
In India today, printing, heat treatment, precision machining and inspection sit with separate vendors, and qualification stalls in the gaps. KRITTVA DNA is building the entire chain into one AS9100-grade flow under a single quality system and a single audit trail.
- STAGE 01
Design & DfAM
Build preparation, simulation and nesting engineered for additive from the first line.
Simulation-led build prep - STAGE 02
Metal AM Print
Laser powder bed fusion in titanium and nickel superalloy, monitored layer by layer.
Ti-6Al-4V · IN718 - STAGE 03
HIP & Heat-Treat
Stress relief, solution and age in-house; hot isostatic pressing through a validated vendor, in the same quality flow.
AMS 2750 pyrometry - STAGE 04
5-Axis Machining
Tight-tolerance CNC, wire EDM and finishing on critical interfaces and datums.
5-axis · Wire EDM - STAGE 05
Test & Certify
In-house lab, NDT, CT and metrology. Every part will ship with its full digital record.
CT · CMM · Metallography
03 · Sectors
Built for the programmes where failure is not an option.
Space
Satellite & launch hardware
Thrusters, valves, RF feed clusters, optical mounts, thermal hardware and bus structures. The part families India's constellation build-out runs on.
Missiles & Defence
Production-rate ordnance, ITAR-free
Control fins, fuze and safe-arm bodies, actuator housings and ramjet injector struts. Sovereign supply for guided-weapon programmes.
Aero Engine & MRO
Hot-section hardware
Fuel nozzles, combustor components and hot-section MRO spares in nickel superalloy. This is where additive geometry earns its keep.
UAV & Airframe
Unmanned systems at volume
Loitering-munition structural and engine nodes, hydraulic manifolds and airframe fittings for the fastest-growing segment in Indian defence.
Medical · From Year 6
Orthopaedic implants, certified
Porous-titanium spinal fusion cages and cementless knee baseplates in Grade 5 Ti-6Al-4V, gated on ISO 13485 for Indian OEMs and export lines.
Nuclear · From Year 6
Reactor-grade components
Fuel-assembly debris filters and safety-class valve trim in IN718 for India's reactor fleet, gated on an NQA-1 quality programme.
04 · The certification stack
Certification is the product. The roadmap is the moat.
Anyone can buy a printer. Earning the accreditations that let a part fly, and keeping them audit after audit, is the discipline this company is built around. Our founder has led AS9100 and NADCAP audits first-hand in the United States.
Phase 1
ISO 9001:2015
The quality-management foundation.
Phase 2
AS9100D
Aerospace QMS: the entry ticket to flight hardware.
Phase 2
DGQA / DRDO
Defence qualification and approval.
Phase 2
ISO/IEC 17025
NABL-accredited materials laboratory.
Phase 3
NADCAP HT
Special-process heat-treatment accreditation.
Phase 4
ISO 13485 + NQA-1
Medical device QMS and nuclear quality assurance: the sixth layer of the stack.
05 · Why KRITTVA DNA
Sovereignty is engineered, not assumed.
One chain, one audit trail
Print, heat-treat, 5-axis machining, EDM, CT and NDT under one roof, with HIP through a validated vendor inside the same quality system, while most facilities scatter those stages across suppliers.
ITAR-free, made in India
Designed around India-made aerospace powder and rupee cost structures. No export gates, no foreign schedules, no compromise on traceability.
Advanced scan strategies
Ring-spot scanning and deep process know-how: parameter development, nesting density and powder lifecycle discipline that a machine purchase alone doesn't include.
A team that has done it before
A decade of building, validating and certifying metal AM to AS9100 and ISO 13485 in the United States, with three operations stood up from scratch.
06 · The parts
Flagship part families, researched part by part.
Twenty-seven flagship part types across Space, Missiles & Defence, Aero Engine, UAV and, from Year 6, Medical and Nuclear, each screened for the geometry, alloy and recurrence where additive wins.
Green bipropellant thruster chamber
Satellite RF feed cluster / waveguide
Ramjet / scramjet injector strut
