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
withstand 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 bigger, so the detail may be less than the other two processes.
what does electronic beam melting (ebm) use to fuse
metal powder together?
a beam of electrons
a sintering furnace
a uv light
an ultrasonic bath

Explanation:

The text clearly states "Electronic Beam Melting (EBM) shoots a beam of electrons to fuse metal powder together".
