Question

fillets
use the information below to answer the question.
reducing stress concentrations on edges and corners before printing can ensure a
better print. this can be done with the use of fillets (also known as radii)
and chamfers. a fillet is a rounded corner used on 3d prints to reduce stresses. a
chamfer is a technique used to cut an outside corner to a 45 - degree angle. these
design techniques also apply to other structures such as concrete and steel.
most technologies will create a natural fillet. with fused filament fabrication, a fillet
the width of the nozzle is naturally made. in selective laser sintering, a natural fillet
of 0.4 mm (the same width as the laser beam) will be on the corners and edges. fillets
and chamfers can be used for inside corners as well to help mitigate the stress in the
design. this is part of the 3d mesh before it goes to the printer.
which of the following processes will have a natural fillet of
0.4 mm on the corners and edges of a print?
material jetting
selective laser sintering
stereolithography
vat polymerization

Explanation:

The text states that in Selective Laser Sintering, a natural fillet of 0.4 mm (the same width as the laser beam) will be on the corners and edges.

Answer:

Selective Laser Sintering
