Title (EN) METHOD AND SYSTEM FOR 3D PRINTING OF ELECTRICALLY CONDUCTIVE POLYMER STRUCTURES
(FR) PROCÉDÉ ET SYSTÈME D’IMPRESSION 3D DE STRUCTURES DE POLYMÈRE ÉLECTRIQUEMENT CONDUCTRICES
Abstract:
(EN) The present disclosure provides a method for producing electrically conductive 3D structures by immersing a substrate having a build surface into a vat containing a liquid photopolymer resin which includes a conjugated polymer, controlling a thickness of a layer of the liquid photopolymer resin on the build surface so that when the liquid photopolymer resin is photopolymerized a base layer of preselected thickness of resin is produced, followed by projecting a beam of radiation having a preselected pattern down onto a top surface of the first layer of the liquid photopolymer resin for long enough to effect photopolymerization of the layer of liquid photopolymer resin; and repeating step a), b) and c) a plurality of times on top of the base layer such each layer of the 3D object is selectively photopolymerized on top of the previously photopolymerized layer to produce the 3D structure. The presence of the conjugated polymer results in the final 3D structure exhibiting electrical conductivity.
(FR) La présente invention concerne un procédé de production de structures 3D électriquement conductrices par immersion d’un substrat ayant une surface de construction dans une cuve contenant une résine de photopolymère liquide qui comprend un polymère conjugué, contrôle d’une épaisseur d’une couche de la résine de photopolymère liquide sur la surface de construction de sorte que, lorsque la résine de photopolymère liquide est photopolymérisée, une couche de base d’épaisseur présélectionnée de résine soit produite, suivie par la projection d’un faisceau de rayonnement ayant un motif présélectionné vers le bas sur une surface supérieure de la première couche de la résine photopolymère liquide pendant une durée suffisante pour effectuer la photopolymérisation de la couche de résine photopolymère liquide ; et répétition des étapes a), b) et c) une pluralité de fois sur la couche de base de sorte que chaque couche de l’objet 3D soit sélectivement photopolymérisée au-dessus de la couche précédemment photopolymérisée pour produire la structure 3D. La présence du polymère conjugué conduit à la structure 3D finale présentant une conductivité électrique.
