Technology & Products
Key Products
["High-Nitrogen Steel (HNS) Metal Powders","Tool Steel and Stainless Steel Powders","Specialty Alloy Powders (Nickel-based, Titanium, Copper alloys)","Additive Manufacturing Services (MoldJet Process)","Component Post-Processing and Finishing","Design Optimization and Process Simulation","Medical-Grade Metal Powder Solutions"]
Technological Advantage
Combines GMH Gruppe's decades of HNS metallurgy expertise with advanced sinter-based additive manufacturing, enabling industrial-scale production of safety-critical components while leveraging green steel production methods and sustainable material sourcing. The MoldJet process allows high-throughput manufacturing (>1,600 cc/hr) with simultaneous part production capabilities.
Differentiation
Value Proposition
Provides end-to-end solutions from certified high-nitrogen steel powder production to ready-to-install components using MoldJet additive manufacturing, combining superior material properties (corrosion resistance, strength, biocompatibility, nickel-free composition) with sustainable production methods using recycled feedstock.
How They Differentiate
Unique integrated value chain combining in-house high-nitrogen steel (HNS) powder production from recycled feedstock with MoldJet sinter-based additive manufacturing and final processing capabilities. Specializes in nickel-free, biocompatible HNS alloys with exceptional strength (>2000 MPa) and corrosion resistance, leveraging GMH Gruppe's 30+ years of metallurgy expertise. Unlike competitors who focus solely on powder supply or AM equipment, ProMateria delivers ready-to-install components with superior material properties using sustainable green steel production methods.
