DAVID metal 3D printer developed by Merain
is an SLM metal 3D printer using a PBF method.
PBF(Powder Bed Fusion) is a layered manufacturing method
repeating the process of using a laser to irradiate path
data corresponding to each layer through a process called slicing
based on process variables from 3D data, then thinly applying
small metal powder with a spherical shape between the size
of 15um~45um on the bed for each layer, then melting it again with
a laser as if drawing a picture, and then applying metal powder again.
