Question

powder bed fusion technologies (pbf)
use the information below to answer the question.
powder bed fusion (pbf) only uses metal. there is no sand, plastic, or polymer. powder
bed fusion (pbf) is not a desktop technology, as it is a big machine that uses a lot of
heat. while selective laser sintering (sls) uses a bed of polymer powder, pbf uses a
metal powder. pbf uses support material to help keep the print from warping. unlike
binder jetting, the print is finished when its taken out of the powder box and does not
need to be placed in a furnace.
there are two different fusion bed technologies: direct metal laser sintering and
selective laser melting
direct metal laser sintering

• fuses the particles together
• there isnt a full melt
• uses alloy metals

selective laser melting

• melts the parts together
• it creates a homogeneous part
• uses elemental metals, such as titanium

powder bed fusion (pbf) only uses what type of material?
metal
plastic
sand
resin

Explanation:

The text clearly states "Powder Bed Fusion (PBF) only uses metal. There is no sand, plastic, or polymer."

Answer:

metal
