POLYAMIDBLENDS ENTHALTEND EIN VERSTÄRKUNGSMITTEL FÜR LASERSINTERPULVER
(EN)
POLYAMIDE BLENDS CONTAINING A REINFORCING AGENT FOR LASER SINTERED POWDER
(FR)
MÉLANGE POLYAMIDE CONTENANT UN AGENT RENFORÇANT POUR POUDRE POUR FRITTAGE LASER
Abstract:
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Formkörpers durch selektives Lasersintern eines Sinterpulvers (SP). Das Sinterpulver (SP) enthält mindestens ein teilkristallines Polyamid, mindestens ein Polyamid 6I/6T und mindestens ein Verstärkungsmittel. Darüber hinaus betrifft die vorliegende Erfindung einen Formkörper erhältlich nach dem erfindungsgemäßen Verfahren sowie die Verwendung von Polyamid 6I/6T in einem Sinterpulver (SP), das mindestens ein teilkristallines Polyamid, mindestens ein Polyamid 6I/6T und mindestens ein Verstärkungsmittel enthält, zur Verbreiterung des Sinterfensters (W
SP
) des Sinterpulvers (SP).
(EN)
The present invention relates to a method for producing a moulded body by selective laser sintering of a sintered powder (SP). The sintered powder (SP) contains at least one partially crystalline polyamide, at least one polyamide 6I/6T and at least one reinforcing agent. The invention also relates to a moulded body obtained according to the claimed method and to the use of polyamide 6I/6T in a sintered powder (SP), which contains at least one partially crystalline polyamide, at least one polyamide 6I/6T and at least one reinforcing agent, for broadening the sintering window (WSp) of the sintered powder (SP).
(FR)
La présente invention concerne un procédé pour produire un corps moulé par frittage laser sélectif d'une poudre à fritter (SP). Cette poudre à fritter (SP) contient au moins un polyamide semi-cristallin, au moins un polyamide 6I/6T et au moins un agent renforçant. L’invention concerne en outre un corps formé obtenu par le procédé selon l’invention, ainsi que l’utilisation de polyamide 6I/6T dans une poudre à fritter (SP), comprenant au moins un polyamide semi-cristallin, au moins un polyamide 6I/6T et au moins un agent renforçant, pour augmenter la fenêtre de frittage (W
SP
) de la poudre à fritter (SP).
