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 temperatures 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 piece material facing up. the step - effect can be minimized from the build direction 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 user must have advanced physics knowledge
the technology has many safety factors
the software requires high - level mathematics

Explanation:

The text states that people operating the Direct - Metal Laser Sintering printers are well - trained because there are many safety factors involved with this technology.

Answer:

The technology has many safety factors.
