Technology & Products
Key Products
Laser Metal Deposition (LMD); Vacuum brazing; Heat treatment; Electron beam welding; Thermal spraying; Sintering of MIM parts
Technological Advantage
Proprietary expertise in integrating LMD with vacuum brazing for conformal cooling applications in mold making, optimizing cycle times and part performance; certified to Nadcap, ISO 9001:2015, and EN 9100 standards.
Differentiation
Value Proposition
Reduces lead times and improves material properties through integrated AM and thermal processing, enabling complex part production with enhanced durability and performance.
How They Differentiate
Focuses on service-based AM integration with thermal processing rather than selling printers; offers hybrid solutions (e.g., vacuum brazing + laser sintering) for mold cooling, unlike pure-play AM hardware companies.
Market & Competition
Target Customers
Manufacturers in aerospace, medical technology, energy, and mechanical engineering requiring high-performance metallic assemblies and material refinement.
Industry Verticals
Aerospace; Medical Technology; Energy; Mechanical Engineering; Tool and Mold Making
Competitors
SLM Solutions; EOS; Intech Additive Solutions
