Question

electronic beam melting (ebm)
use the information below to answer the question.
electronic beam melting is a technology used for the powder bed fusion (pbf) process. it is a good process when a user needs to create a metal print that can stand very high temperatures. electronic beam melting (ebm) shoots a beam of electrons to fuse metal powder together. like direct metal sintering, it is created layer - by - layer. metal powder is laid down, but instead of a laser, it uses an electron beam that will melt the metal. it is a faster process because it has higher energy from the electron beam.
the process uses support structures to prevent warping as well. also, it is done in a vacuum and it can handle the strongest alloys in 3d printing. ebm is faster than direct metal sintering and selective laser melting. however, the particle size is larger and the layer thickness is larger, so the detail may be less than the other two processes.
what 3d printing process is electronic beam melting (ebm) a technology of?
fused filament fabrication (fff)
vat polymerization (vat)
material jetting (mj)
powder bed fusion (pbf)

Explanation:

The text clearly states that Electronic Beam Melting (EBM) is a technology used for the Powder Bed Fusion (PBF) process. It shoots an electron - beam to fuse metal powder together layer - by - layer.

Answer:

Powder Bed Fusion (PBF)
