| 摘要 |
The present invention relates to a process comprising a step of heat treatment of a polyamide-based powder so as to reduce the difference between the initial crystal rearrangement temperature and the final crystal rearrangement temperature. The invention also relates to articles obtained by using powders that have undergone this treatment, in particular by selective melting of layers of polymer powder, in particular rapid prototyping by solid-phase sintering using a laser. |
