▎ 摘  要

NOVELTY - Additive manufacturing system 10 comprises build platform 14 configured to support the portion as it is formed, additive manufacturing material reserved that retains an additive manufacturing material 16 including fluorine-containing polymers, that are electrically conductive and static dissipating and supplemental material including graphite, graphene, and carbon. The system also comprises a functional material reserve 18, which retains functional material set to promote mixing of the fluorine-containing polymers with the supplemental material when added to the additive manufacturing material. A mixer downstream of additive manufacturing material reserve and functional material reserve, where mixer is configured to selectively add functional material to additive manufacturing material to form additive manufacturing material mixture. A material depositor downstream of mixer, and a material depositor is set to deposit additive manufacturing material mixture onto build platform. USE - Additive manufacturing system for forming portion via additive manufacturing, where additive is stereolithographic additive (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of forming a portion via additive manufacturing, involves: (1) Depositing additive manufacturing material onto a build platform, where additive manufacturing material include fluorine-containing polymers are one of electrically conductive and static dissipating; (2) Cross-linking portions of the deposited additive manufacturing material; and (3) Curing the selectively cross-linked portions such that the portion is one of electrically conductive and static dissipating. DESCRIPTION OF DRAWING(S) - The drawing shows perspective view of an additive manufacturing system. Additive manufacturing system (10) Build platform (14) Additive manufacturing material (16) Functional material reserve (18) Feeder (22)
