摘要
A consumable material configured for use in an additive manufacturing system includes a polymeric matrix having polyetherersulfone (PES) in a range of between about 30 wt % and about 85 wt % of the polymeric matrix and polyphenylene sulfide (PPS) in a range between about 15 wt % and about 70 wt % of the polymeric matrix, wherein the polymeric matrix is in a media form suitable for processing in the additive manufacturing system and having a Tg that is about 190° C. or greater and a coefficient of thermal expansion of less than about 30 μm/(m·° C.). The consumable material is suitable for use in 3D printing of composite mold tools.
