VERFAHREN ZUM HERSTELLEN VON FORMTEILEN AUS CARBON ODER GRAPHIT MITTELS 3D-DRUCK
A process for 3D printing articles made of carbon or graphite includes producing a flowable polymeric mixture from a UV permeable and polymerizable polymer or cellulose and a UV crosslinkable resin, admixing the polymeric mixture with sugar and/or cellulose until the mixture has a consistency such that it can be filled into a 3D printer and processed thereby, homogenizing the mixture at room temperature or elevated temperature, filling a 3D printer with the mixture, layerwise printing a shaped article with simultaneous exposure to UV radiation for layerwise crosslinking of the UV crosslinkable resin, cleaning the shaped article, introducing the UV precured shaped article into a furnace and stabilizing the UV precured shaped article in air at a predetermined stabilizing temperature until all volatile constituents have outgassed from the prefabricated shaped article and subsequently high temperature treating the shaped article for carbonization or graphitization in a furnace under protective gas.
