Question

fff: the abcs of support
use the information below to answer the question.
there are a few rules to keep in mind with fused filament fabrication (fff) to avoid or minimize the support structure used. it is also important to note that the support structure can be added to the parts automatically with the software or it can be added manually by the operator. instead of abcs, this process focuses on the yhts, which have to do with the angle and bridging.
y: in terms of support, \y\ relates to the angle of the support. if the angle is greater than 45 degrees, a support structure is not needed.
h: in terms of support, \h\ relates to the crossbar. the crossbar will need support if it is greater than 1 cm or 10 mm. the support does not need to be solid. however, there needs to be enough support so that when bridging occurs, it will meet up properly. with fff, the ability to bridge gaps between supports is also available.
t: in terms of support, the arms of the \t\ relate to the cantilevers. the \t\ will need a support structure if printed unless cantilevers are used. the cantilever must be 3 mm or less.
in terms of support, which acronym is used to describe the focus of fused filament fabrication (fff)?
acps
krws
cads
yhts

Explanation:

The text clearly states that instead of ABCs, the FFF process focuses on the YHTs which are related to angle and bridging.

Answer:

YHTs
