Capabilities · Full-stack AM
A printed part is worthless to a defence programme until it is finished to machined tolerances, heat-treated to full properties, inspected to acceptance criteria and documented end to end. KRITTVA DNA is building those stages in-house in a purpose-built Bangalore facility, with hot isostatic pressing through a validated vendor: one flow, one quality system, one audit trail.
01 · The process
A laser selectively melts fine metal powder in micron-thin layers inside an inert argon chamber, fusing it into fully dense metal.
A recoater lays a powder layer; the laser fuses the part's cross-section.
The build plate steps down by less than a hair's width and the cycle repeats, thousands of times.
Argon shielding keeps oxygen low for clean, crack-free metallurgy.
Heat-treat, 5-axis machining and CT turn the raw build into a qualified part, with HIP through a validated vendor.
02 · The platform
The Phase-1 platform is specified around the flagship-part envelope and an AS9100-grade flow: every machine selected for the chain, not the brochure.
Third-generation metal printing with ring-spot scan strategy, on dedicated titanium and nickel-superalloy lines in a cleanroom print bay.
Dedicated Ti-6Al-4V and IN718 linesSimultaneous 5-axis machining sized to the full flagship-part envelope, for tight-tolerance finishing of critical interfaces and datums.
Simultaneous 5-axis finishingStress relief, solution treatment and ageing run in-house to aerospace pyrometry standards; hot isostatic pressing through a validated vendor in the same quality flow.
AMS 2750 pyrometryBuild-plate cut-off, support removal and automated powder recovery: the unglamorous stages that decide yield.
Wire EDM cut-offIndustrial computed tomography, fluorescent penetrant inspection, radiography and coordinate metrology, with 100% inspection on flight hardware.
Industrial CT scanningChemistry, mechanicals and metallography in-house, on the ISO/IEC 17025 (NABL) accreditation roadmap, offered as a service as well.
ICP-OES chemistry03 · The facility
A half-acre site fitted out to AS9100-grade from day one: Class 10K cleanroom printing environment, argon infrastructure, and a floor planned around the flow of a part, not the footprint of the machines.
Designed for 24/7 production. Three-shift operations with dedicated quality and lab engineering on every shift, and expansion headroom engineered into the building from the start.
04 · Materials
Metal powder is the input a defence programme audits hardest. We design around India-atomised aerospace powder: duty-free, defence-approved, traceable and sovereign. Never material a qualification authority would reject.
The aerospace workhorse: highest strength-to-weight for airframe fittings, satellite structures, control surfaces and payload hardware.
Satellite structures · missile fins · bracketsStrength at temperature for the hot end: fuel nozzles, thrusters, turbopump hardware, fluid systems and fuze bodies.
Propulsion · hot-section · fluid systemsFrom Year 6, medical implant production runs Grade 5 Ti-6Al-4V (ASTM F1472) from the same India-atomised supply, in batch-segregated lots under ISO 13485.
05 · Quality & certification
A six-certification stack, each layer earned over years and kept audit after audit. Our founder has personally led AS9100 and NADCAP audits in the United States. KRITTVA DNA's quality system is being authored before the first machine arrives, not after.
