Title: SYSTEMS AND METHODS FOR ADDITIVE MANUFACTURING OF HYBRID MULTI-MATERIAL CONSTRUCTS AND CONSTRUCTS MADE THEREFROM
Abstract:
A simultaneous thermoplastic and thermoset deposition system is provided that includes a substrate holder, a thermoplastic molten-material extruder, photo-polymerizing light source, a prepolymer vat, and a controller, where the controller controls the thermoplastic extruder to deposit a thermoplastic layer according to a thermoplastic pattern on the substrate holder, where the controller controls the substrate holder to immerse the thermoplastic layer in the prepolymer vat for coating the thermoplastic layer with a coating of the prepolymer solution, where the controller controls the substrate holder to position the prepolymer coated thermoplastic layer for exposure to the photo-polymerizing light source, where the controller controls the photo-polymerizing light source to cure the prepolymer coating according to a thermoset pattern on the thermoplastic layer, where the controller iteratively controls the substrate holder, the thermoplastic molten-material extruder, and the photo-polymerizing light source to form a thermoset structure that is integrated to a thermoplastic structure.
