Question

additive manufacturing and filament
what is this type of build plate adhesion?
skirt
brim
raft
colinear

Explanation:

In 3 - D printing, a skirt is a single - layer line of filament that is printed around the perimeter of the object before the actual print starts, mainly for priming the extruder and ensuring proper flow. A brim is a wider, multi - layer extension around the base of the print to improve adhesion. A raft is a separate base structure printed below the object to help with adhesion and leveling. "Colinear" is not a standard build plate adhesion type in 3 - D printing. The green line around the base in the image is a single - layer perimeter, which is characteristic of a skirt.

Answer:

A. skirt
