Question

sls: stepping effect
use the information below to answer the question.
the stepping effect is inherent in the sls printing process. it occurs when a smooth edge comes out wavy or stepped. there are strategies to minimize that effect.
part orientation
the stepping effect is most pronounced when the part is horizontal to the build plate. reorienting the piece so that it is vertical will minimize the effect as part of the process.
smoothing
if the file is uploaded for a third party to print, they may have post - processing options to do vapor smoothing or polishing.
holes
when an sls print has holes, a user can print the hole undersized and then machine it with a drill press after printing to mitigate the stepping effect. sanding or filing can also be used, depending on the accuracy needed.
to mitigate the stepping effect on print holes, a user can print the hole undersized and then machine it with what?
a drill press
a table saw
a kiln
a hammer

Explanation:

We refer to the "Holes" section in the given information, which states that when an SLS print has holes, a user can print the hole undersized and then machine it with a drill press after printing to mitigate the Stepping Effect. A table saw is for cutting wood or other materials in a planar way, a kiln is for firing ceramics or heating materials, and a hammer is for striking, none of which are suitable for machining a hole. So the correct option is the one with a drill press.

Answer:

a. a drill press
