Question

shrinkage and warping
use the information below to answer the question.
shrinkage and warping can happen to prints done with a heat process or a resin process when curing.
causes
in a process that uses heat, such as fused filament fabrication (fff), there can be a heat gradient that causes the material to bend. this can continue with each layer. this is caused by the shrinkage from the differential in heat as each layer is laid down.
the other cause of warping is due to differential curing, which has nothing to do with heat. in a process such as sla, the material will shrink somewhat from the layer above it, which can cause it to warp.
prevention strategies
controlling the atmosphere or ambient heat will help prevent warping. keep the environment as consistent as possible. having an enclosure is a good way to do that. support structure helps prevent warping due to shrinkage as well. having the print anchored to the bed will reduce the likelihood of warping.
design techniques can also help prevent warping. keep a uniform wall thickness throughout whenever possible. avoid long, flat pieces. breaking up the surface into two (or more) pieces, if possible, will reduce the chance of warping.
what is one way to prevent a print from warping?
designing prints to be hollow
orientating prints horizontally
using a higher amount of heat
using a support structure

Explanation:

The text mentions that support structure helps prevent warping due to shrinkage.

Answer:

using a support structure
