Method & Evidence

AimTo develop and evaluate a method for in-envelope hybrid additive and subtractive manufacturing of multi-material components, specifically addressing the interface challenge between metal and polymer.
MethodExperimental research and prototyping
ProcedureA five-axis mill was integrated with a polymer additive manufacturing system. A mechanically interlocking root structure was designed to create an interface between machined aluminum and printed carbon fiber reinforced acrylonitrile butadiene styrene (ABS). The performance of the polymer deposition, including overhang geometry reproduction and the relationship between structural performance, cooling, and material flow rate, was assessed. Tensile strength of the resulting metal-polymer objects was measured.
