| 摘要 |
The present invention relates to a method including a step for heat-treating a polyamide powder in order to decrease the difference between the initial crystalline rearrangement temperature and the final crystalline rearrangement temperature. The invention also relates to articles produced using powders that were subjected to said treatment, in particular by selectively melting polymeric powder layers, and in particular rapid prototyping by solid-phase laser sintering. |
