... ( Ref 6 ). As for metals, when polymers are run in laser sintering at room temperature, significant curling or distortion occurs if no support structure is used. Polymers, unlike metals, stress relax at relatively low temperature, so the distortion can be eliminated by heating the powder bed. Typically...
