SUMMARY
Warping in selective laser sintering (SLS) is primarily caused by differential contraction of the sintered material as it cools after being heated by the laser. The mechanism involves the material momentarily melting and then solidifying, leading to distortion due to temperature gradients. Typically, the warping occurs away from the heat source, and the extent of deflection can vary based on material properties and layer thickness.
