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 (fft) 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.
for fused filament fabrication (fff), what does the \y\
refer to in terms of support?
the cantilevers
the crossbar
the contact of the material
the angle of the support

Explanation:

The text explicitly states that for FFF support, "Y" relates to the angle of the support, noting no support is needed if the angle exceeds 45 degrees.

Answer:

the angle of the support
