Therefore Powder Bed Fusion processes are single step processes while binder jetting is a multi-step process. The main advantage of binder jetting is the high build-up rate, which is up to a factor of 50 higher than LPBF. For this reason, the importance of binder jetting has increased significantly in recent years.

3.3.3 Laser powder bed fusion. Laser powder bed fusion uses a laser to selectively melt metal powders in a powder bed (Fig. 5 (c)). This process involves spreading a thin layer of metal powders on the build platform and then melting it using a focused laser [109]. The non-melted powders of the powder bed serve as support for the manufactured parts.

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.
