Abstract
Methods and processes are provided by which inhibited-crystallization polymers may be employed as feedstock materials in thermoplastic extrusion-type additive manufacturing systems. Counteracting the tendency of such polymers to uncontrolledly settle into an amorphous state upon cooling under typically used conditions, techniques are disclosed for controlling process temperatures, exposure times and feed rates to produce parts with uniform crystallinity, high mechanical strength and efficient throughput.
