Document Type and Number:
WIPO Patent Application WO/2021/134433
Kind Code:
A1
Abstract:
The invention relates to a method of additive manufacturing an object using a 3D printing apparatus, in which at least one layer or part of at least one layer is formed by an addition-crosslinking electro-conductive silicone composition comprising : (A) at least one organopolysiloxane compound A comprising, per molecule at least two C2-C6 alkenyl radicals bonded to silicon atoms, (B) at least one organohydrogenopolysiloxane compound B comprising, per molecule, at least two hydrogen atoms bonded to an identical or different silicon atom, (C) at least one catalyst C comprising at least one metal from the platinum group or the compound thereof, (D) at least one reinforcing silica filler D, (E) at least one thixotropic agent which is selected from compounds having epoxy group, (poly) ether group, and/or (poly) ester group, organopolysiloxane having an aryl group and mixtures thereof; (F) at least one electro-conductive filler F, which is selected from nickel coated carbon, preferably graphite, graphene or mixtures thereof; (G) optionally at least one crosslinking inhibitor G.
