Metal Powder (DMLS/SLM)

3D Printing

Atomized metal powders optimized for laser powder bed fusion processes including Direct Metal Laser Sintering and Selective Laser Melting. Powder feedstock must meet strict particle size distribution, flowability, and oxygen content specifications.

Metal additive manufacturing (AM) is transforming how we design and produce metallic components. By building parts layer by layer from metal powder or wire feedstock, 3D printing enables geometries impossible with traditional manufacturing — internal cooling channels, topology-optimized lattices, and patient-specific implants. The global metal AM market exceeded $3 billion in 2024 and is projected to surpass $10 billion by 2030.

Material Requirements

AM alloys must form stable melt pools under laser or electron beam energy, solidify without hot cracking, achieve near-full density (>99.5%), and develop acceptable microstructures without extensive post-processing. Powder characteristics (sphericity, particle size distribution 15-45 µm for LPBF, flowability) directly affect print quality. Post-processing — stress relief, HIP (hot isostatic pressing), and machining — is typically required for critical applications.

Key Alloys

Ti-6Al-4V dominates aerospace and medical AM applications. Inconel 718 and 625 are proven for gas turbine components. Stainless steel 316L is the most widely printed steel alloy. AlSi10Mg provides good strength and thermal conductivity for automotive and heat exchanger parts. Maraging steel 18Ni300 offers ultra-high strength (2,000 MPa) for tooling inserts and mold cores. CoCrMo is standard for dental frameworks and orthopedic implants.

Future Trends

New AM-optimized alloys (not legacy wrought compositions) are being designed specifically for rapid solidification — aluminum-cerium and aluminum-scandium alloys resist hot cracking that plagues conventional high-strength aluminum in AM. Multi-material printing (gradient alloys, functionally graded materials) is moving from research to production. In-situ process monitoring with AI-driven quality control is reducing the need for destructive testing.
