Question

pbf: common applications
use the information below to answer the question.
direct metal laser sintering (dmls) is a process using powder bed fusion (pbf)
to heat and melt metal together, adding layers, to create real world applications for
small and highly customized models. the dmls process is suited for dental and
medical purposes, as well as specialized industrial metal parts.
how is powder bed fusion (pbf) used when making a metal
part with dmls?
by adding different color dyes to create the surface of a metal part
by heating and melting metal together layer by layer to create parts
by adding different support structures to uphold the look of the metal part

Explanation:

The text clearly states that Direct Metal Laser Sintering (DMLS) uses Powder Bed Fusion (PBF) to heat and melt metal together, adding layers. So we just need to match this description with the given options.

Answer:

by heating and melting metal together layer by layer to create parts
