Title (EN) METHOD FOR MANUFACTURING A THREE-DIMENSIONAL OBJECT USING DIMENSIONALLY STABLE AND WATER SOLUBLE POLYAMIDE SUPPORT MATERIAL
(FR) PROCÉDÉ DE FABRICATION D'UN OBJET TRIDIMENSIONNEL À L'AIDE D'UN MATÉRIAU DE SUPPORT EN POLYAMIDE DIMENSIONNELLEMENT STABLE ET HYDROSOLUBLE
Abstract:
(EN) The invention pertains to a method for manufacturing a three-dimensional object with an additive manufacturing system comprising providing a support material comprising more than 50 % wt. of a well-chosen polyamide. The polyamide can be a semi- crystalline polyamide having a melting point (Tm), as determined according to ASTM D3418, of from 100 °C up to less than 250 °C, which, when immersed in water at a concentration of 250 g/l, is soluble in water, is dispersed in water or is swollen by water with a water uptake at saturation of at least 25 % by weight, based on the initial weight of the polyamide. An exemplary polyamide is the condensation product of adipic acid with a diamine commercialzed by Huntsmann Chemicals as Jeffamine® EDR-148.
(FR) L'invention concerne un procédé de fabrication d'un objet tridimensionnel assorti d'un système de fabrication additive consistant à obtenir un matériau de support contenant plus de 50 % en poids d'un polyamide bien choisi. Le polyamide peut être un polyamide semi-cristallin ayant un point de fusion (Tm), tel que déterminé selon la norme ASTM D3418, allant de 100 °C jusqu'à moins de 250 °C, qui, lorsqu'il est immergé dans de l'eau à une concentration de 250 g/l, est hydrosoluble, dispersé dans l'eau ou gonflé par l'eau avec une absorption d'eau à saturation d'au moins 25 % en poids, par rapport au poids initial du polyamide. Un exemple de polyamide est le produit de condensation de l'acide adipique comprenant une diamine commercialisé par la société Huntsmann Chemicals sous l'appellation Jeffamine® EDR-148.
