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 attached 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 part oriented flat up. the step - effect can be minimized from the build orientation as well. what does the support structure in powder bed fusion (pbf) prints help to prevent? melting; color inconsistencies; rough textures; warpage

Explanation:

The text mentions that due to high temperatures in Powder Bed Fusion (PBF), a support structure is needed to prevent warping. It is attached to the build bed and dissipates heat during layer - building.

Answer:

warpage
