Question

fff: design strength strategies
use the information below to answer the question.
there are four ways you can strengthen a fused filament fabricated piece: infill, stat,
refactoring, and origami.
infill
a 100% infill piece will be strong and rigid. however, it might tend to crack and
separate. 60% infill is best for a fused filament fabrication (fff) piece.
stat
with this strategy, a user breaks apart their model and prints it in three pieces. the
pieces are then bolted together. this is an opportunity to use holes and mechanical
fasteners. this technique overcomes weakness in the z - axis.
re - fracturing
this strategy is similar to the stat technique in that the print is sliced into three
sections. each component is oriented in a different direction or plane. the goal is to
have a strong plane against a weaker plane. depending on the geometry of the piece,
this could reduce the amount of support structure, optimize bridging, or optimize
surface area. the face that is closest to the print bed will be the smoothest.
origami
this technique is used if a user is printing an object such as a cube by unfolding it and
printing it flat. between each edge, there is a layer of 2mm. after removing it from the
bed, it can be folded, hence the term origami. there is a built - in plane - against - plane
structure, which is light. this is a good technique when there is a thin wall and simple
geometry.
in terms of fused filament fabrication (fff), origami is a
good technique when there is what?
a porous material and no support structure
a heavy base and rounded edges
a dense design and complex shape
a thin wall and simple geometry

Explanation:

The text about the Origami technique in FFF clearly states that it is a good technique when there is a thin wall and simple geometry.

Answer:

a thin wall and simple geometry
