Question

fff: design table
use the information below to answer the question.
wall thickness
wall thickness is one of the most important aspects of fused filament fabrication
(fff). a print should never be smaller than 2 times the width of the nozzle or two
paths around. for most desktop printers, the nozzle is.4 mm in diameter, so the
minimum thickness would be.8 mm. a print should have at least two paths of
filament, but three or four is better.
overhangs
an overhang greater than 45 degrees does not require support material. overhangs
with less than 45 degrees will need support material.
engraved & embossed
for engraved letters, there shouldnt be anything smaller than 0.6 mm wide, or 2
times the nozzle width. for embossed letters, the minimum is 0.2 mm wide.
which of the following is true about overhangs less than 45
degrees?
they require a support structure.
they will lead to a high amount of shrinkage and warping.
they should not be used for fused filament fabrication (fff).
they do not require support structures.

Explanation:

The text states that overhangs with less than 45 degrees will need support material.

Answer:

They require a support structure.
