Beschreibung
Zusammenfassung:	A method and apparatus for forming three dimensional flame retardant objects by laser sintering that includes homogeneously combining, by an extrusion process, certain polymer materials with nanoparticles and using the resultant powder in a laser sintering device to produce freeform parts. L'invention concerne un procédé et un appareil permettant de produire des objets ignifuges tridimensionnels par frittage au laser. Ledit procédé consiste à combiner de manière homogène, par procédé d'extrusion, certains matériaux polymères disposant de nanoparticules et à utiliser la poudre ainsi obtenue dans un dispositif de frittage au laser pour produire des pièces de forme libre.
