ABSTRACT
A
ccomplishing dramatic reductions in the manufacturing cost of composite
structures requires a combination of developments in automated processes,
high speed material application and reduced dependence on hard tooling methods.
To benefit high performance aerospace applications these developments are best
accomplished on processes suitable to continuous fiber composites. The Continuous
Fiber 3D Printing (CF3D®) process, a newly developed technology for additive
manufacturing of continuous fiber composites, offers the combination of necessary
attributes to revolutionize the manufacture of low cost, high performance composites.
This paper provides a description of the technology, ongoing development efforts,
and plans for future improvements and applications. Initial aerospace application is
focused on the USAF Low Cost Attritable Aircraft Technology (LCAAT) program, but
opportunities for exquisite airframe applications, including cost effective fabrication of
topology optimized structures and multifunctional material options is also discussed.
