Abstract
A method of providing improved powder materials for selective laser sintering (SLS). and related sintering including High Speed Sintering and Selective Inhibition Sintering, processing by orienting a polymer material. The improved materials increase the melting temperature thus increasing the process temperature window, reduce or eliminate amorphous regions thus reducing water absorption, reduce the toughness thus making size reduction easier, and increase heat of fusion. The orientation may be accomplished by deforming the polymer by drawing, rolling, machining, equal channel angular extrusion or similar processes, or by a high shear two roll mill.
