Abstract: An additive manufacturing feedstock production system includes a transition roller configured to combine reactive metal foils into combined reactive metal foils with a first combined thickness. The additive manufacturing feedstock production system includes a work roller configured to compress the combined reactive metal foils to a second combined thickness less than the first combined thickness, and a first processing module configured to segment and stack the combined reactive metal foils into stacked reactive metal foils, and feed the stacked reactive metal foils into the work roller. The work roller is configured to repeatedly compress the stacked reactive metal foils into compressed stacked reactive metal foils with a stacked thickness equal to the second combined thickness. The additive manufacturing feedstock production system has a second processing module configured to segment the compressed stacked reactive metal foils into a wire feedstock.

Abstract: An additive manufacturing apparatus includes powder supplies, a preceramic binder supply, and a mixer device downstream from the powder supplies and the preceramic binder supply and configured to generate a powder-integrated preceramic mixture. The additive manufacturing apparatus also includes a nozzle device downstream from the mixer device and configured to output the powder-integrated preceramic mixture, and a heat source configured to heat the powder-integrated preceramic mixture to initiate a self-sustainable ceramization reaction to generate a ceramic matrix composite.
