Question

pbf: printer characteristics
use the information below to answer the question
characteristics
the printer for direct metal laser sintering is very large and weighs one and a half tons - 3,000 pounds. the people operating the printer are very trained because there are many safety factors involved with this technology. because of the high temperature used, a support structure is also needed to prevent warping. the support structure is anchored to the build bed and dissipates heat as each layer is being built. if a smooth surface is needed, orientation on the build plate is important. this can be communicated to the operator. the greatest opportunity for a smooth surface is to have the piece oriented facing up. the step effect can be minimized from the build orientation as well
what is required for powder bed fusion (pbf) prints due to the high temperatures involved?
a support structure
a cooling agent
an insulation material
a wax covering

Explanation:

The text states that due to high temperatures in Powder Bed Fusion (PBF) prints, a support structure is needed to prevent warping.

Answer:

a support structure
