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 part 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 powder completely - is created a homogeneous part - uses elemental metals, such as ti which of the following is true about powder bed fusion (pbf)? it is often infused with a bronze additive. it is not a desktop technology. it does not require a heat source. it uses a combination of sand and metal.

Explanation:

The text states that Powder Bed Fusion (PBF) is not a desktop technology as it is a big machine that uses a lot of heat. It only uses metal powder, requires a heat source, and does not use sand. There's no mention of it being infused with a bronze additive.

Answer:

It is not a desktop technology.
