Column - Differences in Metal 3D Printing Methods (with PDF materials)

MBJ, SLM, DED, EBM... There are various types of metal 3D printing, and I will explain the differences. 1. SLM and EBM This method involves melting a layer of powder (Powder Bed) locally using a laser or electron beam to create the object. It is also called Powder Bed Fusion. SLM stands for Selective Laser Melting, and EBM stands for Electron Beam Melting. Different manufacturers may use other abbreviations. 2. DED and BPT This is a micro-additive manufacturing method that locally melts powder while supplying it with a laser. DED stands for Directed Energy Deposition, and BPT stands for Blown Powder Technology. 3. Binder Jetting This method solidifies the Powder Bed with a binder (adhesive) to create the object. After forming, debinding (removal of the binder) and sintering are necessary, but the material does not melt. It is abbreviated as MBJ (Metal Binder Jet). - Summary There are three types of metal 3D printing: PBF, DED, and MBJ. MBJ creates objects without melting the material.
