3D Printing / LMD - Direct Metal Deposition

LMD uses high‑quality steel and alloy powders with controlled chemistry, particle size, and purity. Key quality features include certified powder batches, full traceability, precise process control, and inspection to ensure consistent microstructure and performance.

Laser Metal Deposition (LMD), also known as Direct Metal Deposition, is an additive manufacturing technology used for near‑net‑shape production, repair, and cladding of high‑performance components. The process places exceptional demands on material quality, particularly when using metal powders. Powder characteristics such as particle size distribution, sphericity, flowability, and chemical consistency are critical to ensure stable deposition, uniform layer formation, and reproducible mechanical properties.

Steels and alloys commonly processed by LMD include low‑alloy steels, stainless steels, maraging steels, tool steels, and nickel‑based alloys. Powders must exhibit high purity, low oxygen content, and minimal contamination to prevent defects such as porosity, cracking, or inconsistent microstructures. Material behavior during rapid melting and solidification must be well controlled to achieve fine, homogenous grain structures. Key quality features include certified powder batches with full traceability, controlled storage and handling, validated process parameters, and post‑process heat treatment. Combined with non‑destructive testing and metallurgical evaluation, these measures ensure mechanical integrity and performance comparable to conventionally manufactured parts.
