Deformation in selective laser sintering

  1. Aug 4, 2014 #1
    I am wondering what causes warping in laser sintering? Can someone explain the mechanism to me?
    For a single layer, which direction will it warp in? (towards or away from heat source), and how big is the deflection is it usually?

    I would expect the sinter material to momentarily melt, then to solidify.
    As the solid cools the differential contraction introduces distortion.
