Title
(EN) A SYSTEM FOR OBTAINING A PHOTOPOLYMERIZED PREPOLYMER
(FR) SYSTÈME POUR OBTENIR UN PRÉPOLYMÈRE PHOTOPOLYMÉRISÉ
Abstract
(EN)
A system for obtaining a photopolymerized prepolymer for use as a component of a material suitable for manufacturing buildings or building components by 3D printing processes. The system contains a flexible closed loop conveyor stretched between a precursor loading station and a prepolymerization material receiver from which the product is unloaded to a construction 3D printing machine. The conveyor carries a plurality of flexible trays capable of looping around the pulleys of the closed loop conveyor. The trays are shallow troughs that have open tops and carry dosed portions of the precursor, which is photopolymerized on its way from the loading station to the unloading station by sequentially passing under light sources of two photopolymerization stations. When the trays pass through the unloading position, they are turned upside-down and allow the precured material to fall into a receiver.

L'invention concerne un système pour obtenir un prépolymère photopolymérisé destiné à être utilisé en tant que composant d'un matériau approprié pour la fabrication de bâtiments ou de composants de bâtiment par des procédés d'impression 3D. Le système contient un convoyeur à boucle fermée souple étiré entre une station de chargement de précurseur et un récepteur de matériau de prépolymérisation à partir duquel le produit est déchargé vers une machine d'impression 3D de construction. Le convoyeur transporte une pluralité de plateaux souples capables de former une boucle autour des poulies du convoyeur à boucle fermée. Les plateaux sont des auges peu profondes qui comprennent des dessus ouverts et transportent des portions dosées du précurseur, qui est photopolymérisé sur son trajet depuis la station de chargement jusqu'à la station de déchargement par passage séquentiel sous les sources de lumière de deux stations de photopolymérisation. Lorsque les plateaux passent à travers la position de déchargement, ils sont retournés et permettent au matériau prédurci de chuter dans un récepteur.
