Powder bed fusion (PBF) is a 3D printing method that joins powdered material point by point using an energy source, typically a laser beam or an electron beam. Powder bed fusion is one of the most common 3D printing techniques used for industrial additive manufacturing (AM).
Powder bed fusion (PBF) is an additive manufacturing, or 3d printing, technology that uses a heat source—typically a laser—to sinter or fuse atomized powder particles together. Like other additive processes this is done one layer at a time until the part is completed. Selective laser sintering machines fuse thermoplastic parts together.
Schneck et al. employed laser-powder bed fusion (LBPF) to produce a case study on multi-material injection nozzle with tool steel 1.2709 and copper alloy CW106C [Citation 27]. Severe defects were detected near the vertical bi-metallic interface, which resulted in part delamination and the failure of the entire component.
Abstract. Powder Bed Fusion (PBF) is an Additive Manufacturing (AM) process. It is the layer by layer addition process. In the future, it is going to be manufactured all types of products used in automotive, aerospace, energy sectors and home appliances. These products can be produced using various AM methods.
The processing parameters in the powder bed fusion processes include layer thickness ( t ), laser power ( P ), laser scanning speed ( v) and scanning path strategy, hatching space ( h) and laser spot size ( d ), particle size and distribution, platform pre-heating temperature and laser beam scanning strategy (see Fig. 2.2 ).
Laser Powder Bed Fusion is a powder bed based additive manufacturing process that is most widely used in the industry.

Gradient models of moving heat sources for powder bed fusion applications. In this paper, we derive closed form solutions for the quasi-stationary problems of moving heat sources within the gradient theory of heat transfer.

Multimaterial powder bed fusion techniques. The multimaterial process can be described as where multiple materials are used (in a single process) for fabricating a 3D part ( Thompson et al., 2016; Vaneker et al., 2020; Gibson et al., 2007; Mohammed et al., 2021 ). But, the use of multiple materials in a powder affects the whole process chain
