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.
why must the people who operate direct metal laser
sintering printers be very trained?
the printers are more fragile than other printers.
the technology has many safety factors.
the software requires high - level mathematics.
the user must have advanced physics knowledge.

Explanation:

The text clearly states that "the people operating the printer are very trained because there are many safety factors involved with this technology."

Answer:

The technology has many safety factors.
