Title (EN) A PROCESS AND A THERMOPLASTIC COMPOSITION FOR ADDITIVE MANUFACTURING
(FR) PROCÉDÉ ET COMPOSITION THERMOPLASTIQUE POUR FABRICATION ADDITIVE
Abstract:
(EN) Method for fabricating products through additive manufacturing, comprising the steps; a) computing a first and second rendition of a digital three dimensional model, the first being a carrying structure and the second an outer surface, b) printing the first rendition with low resolution using a thermoplastic composition comprising a polyester having a molecular weight in the range 10.000 – 150.000 MW and a performance additive selected from the group; CaCO3, mica, talcum, cellulose, dolomite, starch, graphite, graphene, graphene oxide, graphyne, graphdiyne and combinations thereof. c) printing the second rendition onto the first with a high resolution, using a thermoplastic composition comprising a polyester having a molecular weight in the range 10.000 – 120.000 MW and a performance additive selected from the group; CaCO3, talcum, graphene, graphene oxide, graphyne, graphdiyne and combinations thereof. The invention further relates to use of a thermoplastic composition.
(FR) L'invention concerne une méthode de fabrication de produits par fabrication additive, comprenant les étapes suivantes : a) le calcul d'un premier et d'un second rendu d'un modèle tridimensionnel numérique, le premier étant une structure porteuse et la seconde une surface externe, b) l'impression du premier rendu avec une faible résolution à l'aide d'une composition thermoplastique comprenant un polyester ayant un poids moléculaire dans la plage allant de 10 000 à 150 000 MW et un additif de performance choisi dans le groupe : CaCO3, mica, talc, cellulose, dolomite, amidon, graphite, graphène, oxyde de graphène, graphhyne, graphdiyne et des combinaisons de ceux-ci, C) l'impression du second rendu sur le premier avec une haute résolution, à l'aide d'une composition thermoplastique comprenant un polyester ayant un poids moléculaire dans la plage allant de 10 000 à 120 000 MW et un additif de performance choisi dans le groupe : CaCO3, talc, graphène, oxyde de graphène, graphhyne, graphdiyne et des combinaisons de ceux-ci. L'invention concerne également l'utilisation d'une composition thermoplastique.
