Question

pbf: printer characteristics. use the information below to answer the question. why must the people who operate direct metal laser sintering printers be very trained? the printer for direct metal laser sintering is very large and weighs one and a half - 1,500 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. also, if a smooth surface is needed, orientation on the build plate is important. this can be controlled by the operator. the greatest opportunity for a smooth surface is to keep the parts sintered facing up. the step effect can be minimized from the build orientation as well. the user must have advanced physics knowledge. the technology has many safety factors. the printers are more fragile than other printers. the software requires high - level mathematics.

Explanation:

The text states that operators are well - trained due to many safety factors associated with the technology. There is no mention of advanced physics knowledge requirement, printer fragility compared to others, or high - level mathematics for software in the provided reason for training.

Answer:

The technology has many safety factors.
