“We’re seeing some really good fits for additive manufacturing in composites tooling,” confirms project engineer Dan Cottrell at Aurora Flight Sciences (Manassas, VA, US). “We’ve been looking at this for years, but now the technologies are getting better,” one tooling expert recently confided to CW, citing the availability of faster, larger and less-expensive AM machines and higher-temperature materials that address some previous issues with rapid moldmaking. Short carbon fiber compounds expand reach of thermoplastic compositesĪlthough AM’s most obvious advantage is direct part production without tooling, the growing trend in the aerospace and automotive sectors at present is its use for fast, on-demand builds of mold tools to keep pace with accelerating composite part design cycles and demand for faster overall part processing speeds.
