Title (EN) BLOCKING GROUPS FOR LIGHT POLYMERIZABLE RESINS USEFUL IN ADDITIVE MANUFACTURING
(FR) GROUPES DE BLOCAGE POUR RÉSINES POLYMÉRISABLES PAR LA LUMIÈRE UTILES DANS LA FABRICATION ADDITIVE
Abstract:
(EN) Provided herein is a method of forming a three-dimensional object in which the polymerizable liquid includes a mixture of (i) a light polymerizable first component, and (ii) a heat polymerizable second component; the heat polymerizable second component comprising (i) a first blocked reactive constituent that is blocked with a volatile blocking group, and optionally (ii) a curative. Upon heating a formed three-dimensional intermediate sufficiently, the volatile blocking group is cleaved and vaporizes out of the three-dimensional intermediate, to form the three-dimensional object. Also provided is a three-dimensional object produced by the method. Further provided is a polymerizable liquid composition useful for carrying out the method, and prepolymers and monomers useful for the polymerizable liquid composition.
(FR) L'invention concerne un procédé de formation d'un objet tridimensionnel dans lequel le liquide polymérisable comprend un mélange de (i) un premier composant polymérisable par la lumière et (ii) un second composant polymérisable par la chaleur ; le second composant polymérisable par la chaleur comprenant (i) un premier constituant réactif bloqué qui est bloqué par un groupe de blocage volatil, et facultativement (ii) un agent de durcissement. Lors du chauffage suffisant d'un intermédiaire tridimensionnel formé, le groupe de blocage volatil est clivé et vaporisé hors de l'intermédiaire tridimensionnel pour former l'objet tridimensionnel. L'invention concerne également un objet tridimensionnel produit par le procédé. L'invention concerne en outre une composition liquide polymérisable utile pour la mise en œuvre du procédé et des prépolymères et des monomères utiles pour la composition liquide polymérisable.
