반-결정성 또는 결정화가능 중합체의 분말의 열 처리를 위한 방법 및 장치. 장치는 분말을 분말의 최고 용융 결정 형태의 용융 온도 미만인 온도로 가열하기 위한 가열 디바이스, 가열 디바이스에 의해 생성된 열에 노출되는 분말을 함유하는 용기, 및 용기 내의 분말이 용기에 대하여 이동하도록 하기 위한 용기 이동을 위한 메커니즘을 포함한다. A method and apparatus for heat treating powders of semi-crystalline or crystallizable polymers. The apparatus includes a heating device for heating the powder to a temperature that is less than the melting temperature of a highest melting crystalline form of the powder, a vessel containing the powder that is exposed to heat produced by the heating device, and a mechanism for moving the vessel to cause the powder within the vessel to move with respect to the vessel.
