Abstract
(EN)
A method for producing an additively manufactured article, comprising a powder material layer forming step of using a powder material for additive manufacturing containing a base material and a resin containing a reactive functional group to form a powder material layer and a cured product forming step of applying, onto the powder material layer, a curing solution containing a curing agent capable of forming a covalent bond with the reactive functional group to form a cured product, wherein the curing agent contains an aliphatic compound having two or more isocyanate groups at the ends of a molecule.
(FR)
L'invention concerne un procédé de production d'un article fabriqué de manière additive, comprenant une étape de formation de couche de matériau pulvérulent consistant à utiliser un matériau pulvérulent pour fabrication additive contenant un matériau de base et une résine contenant un groupe fonctionnel réactif pour former une couche de matériau pulvérulent et une étape de formation de produit durci consistant à appliquer, sur la couche de matériau pulvérulent, une solution de durcissement contenant un agent durcissant apte à former une liaison covalente avec le groupe fonctionnel réactif pour former un produit durci, l'agent durcissant contenant un composé aliphatique ayant deux groupes isocyanate ou plus aux extrémités d'une molécule.
(JA)
