Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector

Compositions and methods for the production of multicomponent composite articles using three dimensionally printed sacrificial tooling is provided. In one embodiment, a multicomponent composite article comprising; 1) three dimensionally printing a sacrificial tool from a soluble material, 2) three dimensionally printing one or more additional materials to create a secondary structure, 3) adding a free-flowing material into the sacrificial tool and contacting the secondary structure, 4) curing the liquid material to a solid state, and 5) dissolving the sacrificial tool with a solvent is described. In another embodiment, the secondary structure is orthogonally soluble and provides a voided composite article once orthogonally removed. Articles of this invention have utility in a wide range of industries, including automotive components, jigs and fixtures, tooling, and aerospace components.
