WHAT IS POWDER BED FUSION

Powder Bed Fusion (PBF) stands as a notable Additive Manufacturing (AM) technique, characterized by its layer-by-layer approach to creating objects. With its potential applications across automotive, aerospace, energy sectors, and household appliances, PBF represents a pivotal future manufacturing method. Alongside PBF, other AM methods like Laminated Object Manufacturing, Direct Energy Deposition, Stereolithography (SLA), and Solid Ground Curing (SGC) contribute to the diverse landscape of additive manufacturing.

This overview will focus on the mechanics of the PBF process, particularly highlighting Direct Metal Laser Deposition (DMLS), Selective Laser Sintering (SLS), Selective Laser Melting (SLM), Electron Beam Melting (EBM), and Selective Heat Sintering (SHS). In these techniques, a layer of powder is spread onto a platform, often referred to as the build platform. While SLS, SLM, and DMLS employ lasers as the primary heat source, EBM utilizes an electron beam. SHS, on the other hand, employs a heated thermal head for sintering plastic powders. Among these methods, SLS, DMLS, and SHS are powder-sintering processes, whereas SLM and EBM are powder-melting processes.
