Question

sls: layer adhesion
use the information below to answer the question.
sls printing has excellent layer adhesion. it is a good option for prototyping and production of injection mold applications. it also has good chemical resistance.
hybrid material
sls creates parts with good tensile strength and mechanical properties. occasionally, carbon or glass fiber is introduced into the build. this can change the material properties of the form. portions of a form that contain additives become stronger in tension and weaker in compression.
porous material
printed parts for sls are about 30% porous, which can make them brittle in some cases. however, this characteristic also means the material can absorb dye, similar to the way a sponge might absorb water. when coloring a form, it is generally done during the post - processing stage.
possible failure
it is important to be aware of any issues that may occur during an sls build. a commonly known problem is called delamination. this is when there isnt enough light or heat. delamination often occurs when the laser is underpowered, or something is obstructing the light getting to the powder bed. for instance, the mirror might be cloudy, or there might be a wedge on the lens.
what quality does sls produce in its parts?
tensile strength
support structures
conductive properties
resin protection

Explanation:

The text states that SLS creates parts with good tensile strength and mechanical properties.

Answer:

tensile strength
