Method for producing graphitised formed parts by means of 3d printing

Abstract

A method produces graphitised formed parts by 3D printing from conventional filaments made of a plastic. It allows producing graphitised 3D formed parts, or another three-dimensional structure made of a thermoplastic material by 3D printing. This is achieved by melting a filament made of a meltable and curable plastic and applying same layer by layer by the 3D printer until the desired structure has been created, stabilising the 3D structure printed from the material of the filament by way of temperature treatment to chemically or crystallographically change the plastic in that pre-stabilisation at ~180° C. is carried out over a longer period, followed by a stabilisation step at ~250° C. until the printed 3D structure is sufficiently dimensionally stable as a stabilised structure and a carbonising or graphitising of the 3D structure, to produce the graphitised structure.
