Powder Bed Fusion technologies use a thermal source (e.g. a laser) to cause fusion between powder particles. Most Powder Bed Fusion technologies use mechanisms for applying and smoothing powder as a part is constructed, resulting in the final component being covered in powder. TL;DR Powder Bed Fusion Technologies SLS – Selective Laser Sintering SLS Industry […]
