Question

sls: powder removal
use the information below to answer the question
in selective laser sintering (sls) 3d printing, support structures are unnecessary, but
hollow prints often retain unsintered powder inside. to address this unsintered
powder, designers incorporate strategically placed escape holes, allowing easy
removal of excess powder. this not only streamlines the cleaning process but also
reduces the print’s weight, leading to cost savings.
print strength
designers have flexibility in choosing the location of escape holes. they can integrate
them seamlessly into the design or hide them strategically. opting not to use escape
holes may compromise the strength of the sls print due to added weight. increasing
the wall thickness of an sls print, coupled with the incorporation of escape holes,
ensures it will have optimal strength.
what is one drawback of choosing not to use escape holes
for sls prints?
color inconsistencies
compromised strength
inadequate support
material overhangs

Explanation:

The text states that not using escape holes may compromise the strength of SLS prints due to added weight. The other options (color inconsistencies, inadequate support, material overhangs) are not mentioned as drawbacks of not using escape holes. So the correct option is the one related to compromised strength.

Answer:

compromised strength
