A method for manufacturing a fiber-reinforced ceramic matrix composite article is provided. The method includes additively manufacturing a carbon fiber-reinforced thermoplastic article via fused filament fabrication (FFF). The article is then thermally annealed to yield an non-meltable article. The method further includes pyrolyzing the non-meltable article to yield a pyrolyzed article. The pyrolyzed article is infiltrated with an infiltration agent to yield a fiber-reinforced infiltrated matrix composite.
