Abstract
(DE)
Die vorliegende Erfindung betrifft die Verwendung einer flüssigen Zusammensetzung, die ein oder mehrere Monomere für die Herstellung eines Polyesters, eines Polyamids oder eines Polyesteramids enthält, wobei zumindest ein Monomer mindestens trifunktional ist, als Bindemittel beim Binder-Jetting-Verfahren. Die Erfindung betrifft außerdem ein Verfahren zur Herstellung eines Formkörpers durch Binder-Jetting.
(EN)
The invention relates to the use of a liquid composition containing one or more monomers for the production of a polyester, polyamide or polyester amide, at least one monomer being at least trifunctional, as a binder in a binder jetting process. The invention further relates to a method for producing a shaped article by binder jetting.
(FR)
La présente invention concerne l’utilisation d’une composition liquide comme liant dans le procédé de projection de liant. La composition contient au moins un monomère destiné à la production d’un polyester, d’un polyamide ou d’un polyester amide. Au moins un monomère est au moins trifonctionnel. L’invention concerne également un procédé de fabrication d’un corps façonné par projection de liant.
