| Abstract Scope |
Despite growing industrial demand for high-performance materials, most ceramic and refractory metal additive manufacturing routes are limited by process constraints. This work outlines a ceramic hybrid additive manufacturing platform (CHAMP) that integrates paste extrusion, green-state machining, and process monitoring within a single system. CHAMP has been proven for a range of technical ceramics, and we now demonstrate its ability to produce cemented tungsten carbide (WC-10Co-4Cr), a material traditionally considered extremely challenging to additively manufacture.
Using CHAMP followed by thermal consolidation, components were produced with ~25% linear shrinkage, sintered densities of 12.35 g/cm³, flexural strength of 573 MPa and Vickers hardness of 1430 HV10, without mechanical post processing. These properties enable application in high wear, high temperature environments, with improvements expected with further densification such as using HIP. This work demonstrates the CHAMP technology as a flexible and scalable route for transitioning additive manufacturing of high-performance materials from prototyping to production. |
