Question

technology summary table
use the information below to answer the question.
below is a section of the technology summary table covering fused filament
fabrication (fff).
using the table on the left, when might a user choose fused
filament fabrication (fff) to create their print?
when they are using a metal powder material group
when their print requires high dimensional accuracy
when they need functional parts at a low cost
when they need a print that does not require a support structure

Explanation:

Looking at the Strength/Weakness section of the FFF table, it mentions "Low Cost" and "Functional Parts" as strengths. So when a user needs functional parts at a low cost, FFF would be a suitable choice. The other options can be ruled out: metal powder is not in the FFF material group; high dimensional accuracy is a weakness (limited dimensional accuracy) for FFF; and support material is required (dissolvable available) so the option about not needing a support structure is incorrect.

Answer:

when they need functional parts at a low cost
