Powder bed fusion (PBF) is an additive manufacturing (AM) technique that selectively coalesces powder particles in a powder bed to create three-dimensional products.
Abstract. Powder Bed Fusion (PBF) was one of the earliest and remains one of the most versatile AM processes, being well-suited for polymers and metals and, to a lesser extent, ceramics and composites. There are an increasing number of machine variants for fusing powders using different energy sources. The most active area of
1.2 Electron Beam Powder Bed Fusion. The electrons in an electron beam travel near the speed of light and interact with atoms in the atmosphere of the build chamber. For this reason, EB-PBF processes are conducted in a vacuum environment with a small amount of inert gas flowing through the chamber to remove spatter particles,

Laser Powder Bed Fusion is a powder bed based additive manufacturing process that is most widely used in the industry. The Fraunhofer IFAM deals with material and process development along the entire process chain of
Laser powder bed fusion (LPBF), also known as selective laser melting (SLM), is widely used in metal additive manufacturing (MAM, also called 3D printing) [1, 2]. It adopts the laser as a power source to melt powder feedstocks and produce final components layer by layer. However, due to the size and shape limitations of the raw
What Are Powder Bed Fusion (PBF) Machines? Powder Bed Fusion (PBF) machines are additive manufacturing, or 3D printing, machines. The process uses thermal energy (laser or electron beam) to selectively melt materials like ceramic, metal, and plastic, in the form of powder, in a layer-by-layer fashion to build a 3D object.
The laser powder bed fusion (LPBF) belongs to a family of additive manufacturing (AM) technique which enables to form layer by layer a more or less complex 3D parts. For metal materials, it
