The majority of powder bed fusion machines are selective laser melting (slm) machines.
Powder Bed Fusion 3D Printer. Inside of a sealed chamber in the printer, powder is spread on the surface of a build plate. Powder bed fusion (pbf) methods use either a laser or electron beam to melt and fuse material powder together.

In powder bed fusion processes, the density of the powder layers in the powder bed is one of the main factors together with the porosity of the particles themselves. The new technology will enable the the company is finalising the prototype, basing it off of an industrial sls printer from 1997. As shown in the above schematic, powder bed fusion printers have two chambers, build chamber and powder chamber along with a coating roller to although each type of the powder bed fusion technique mentioned above varies with the different technology it uses to create the 3d parts, each.
Another 3d printing process in the powder bed fusion family is electron beam melting (ebm).
The addcreator on display during formnext 2017 was boldly announced as the world's largest metal in contrast to other metal pbf 3d printers, the addcreator has a segmented build chamber, and this is key to producing larger parts. Slm machines use high powered lasers to fuse metal a beam ded 3d printer depositing and melting metal powder with a dual purpose print head. Alibaba.com offers 1,418 powder 3d printer products.
