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.
how much does a direct metal laser sintering printer
weigh?
500 - 1000 pounds
1200 - 2000 pounds
220 - 600 pounds
3000+ pounds

Explanation:

The text clearly states that the Direct Metal Laser Sintering printer weighs one and a half tons - 3,000 pounds. Among the given options, 3000+ pounds is the only one that matches this information.

Answer:

3000+ pounds
