Question

fff: support structures and part orientation
use the information below to answer the question.
support structures for fff
a powerful thing to know when choosing fused filament fabrication (fff) is what the
limitations are and the orientation for avoiding support structure. avoiding support
structures can help use less material and print the project more quickly. if the angle is
less than 45 degrees, the print will need a support structure. angles greater than 45
degrees do not require a support structure. the key is to minimize the amount of
support structure for a print. a print will almost always need some support with fused
filament fabrication (fff).
a powerful thing to know when using fused filament
fabrication (fff) is the orientation to avoid which of the
following?
color changes
hollow prints
support structure
material melting

Explanation:

The text clearly states that when using FFF, avoiding support structure through proper orientation is beneficial. It mentions that angles less than 45 degrees need support structure and the goal is to minimize it. So the orientation is to avoid support structure.

Answer:

support structure
