1. Introduction to Selective Laser Melting (SLM) Powder
Selective Laser Melting (SLM) is a cutting-edge additive manufacturing (AM) process that uses high-energy lasers to fuse fine metal powders into dense, complex, and high-performance metal parts layer by layer. The quality, consistency, and composition of metal powders used in SLM directly influence the performance of the final product, making SLM powders a critical component in the metal 3D printing supply chain.
SLM powders are characterized by:
- High Sphericity: Ensures uniform powder flow and layer deposition.
- Controlled Particle Size Distribution (PSD): Typically ranges from 15–45 μm for optimal laser absorption.
- High Purity & Low Oxygen Content: Enhances mechanical properties and prevents porosity.
- Excellent Flowability: Vital for consistent layering and part quality.
For B2B buyers, especially those in aerospace, automotive, medical, and industrial tooling, sourcing high-quality SLM powders is essential for reliable and repeatable production.
Key B2B Keywords:
