  • Method for heat-treating powders
    Patent number: 9512285
    Abstract: 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.
    Type: Grant
    Filed: June 6, 2013
    Date of Patent: December 6, 2016
    Assignee: Rhodia Operations
    Inventor: Cecile Corriol
  • Production of an article by selective fusion of polymer powder layers
    Patent number: 9321192
    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.
