Abstract:
A process is described for manufacturing articles by selective fusion of polymer powder layers, especially the rapid prototyping by solid-phase laser sintering of a powder based on a copolyamide of type 6 having a low enthalpy of cold crystallization. Further described, are the articles obtained by such a process.
