Abstract
The present invention relates to a method for manufacturing a 3D item () by means of fused deposition modelling (FDM), the method comprising the steps of: a) providing a shell component (') comprising a thermoplastic 3D printable shell material having a shell melting temperature (Tms) and/or a shell glass transition temperature (Tgs); b) providing a core component (′) comprising a plurality of thermally conductive wires () and a flexible mantle () enclosing the plurality of thermally conductive wires (); c) feeding the shell component () into a nozzle () of a 3D printer, the nozzle () having a nozzle temperature (Tn) being equal to or greater than the shell melting temperature (Tms) and/or the shell glass transition temperature (Tgs); d) a layer-wise depositing of the 3D printable shell material and the core component () to provide the 3D item () comprising a core-shell layer (′) of 3D printed material, wherein the 3D printed material comprises a core () comprising the core component, and shell () comprising 3D printed shell material, wherein the shell () at least partly encloses the core ().
