Characterization of High-Deposition Polymer Extrusion in Hybrid Manufacturing

Abstract

Hybrid manufacturing processes that include additive and subtractive operations have unlocked many of the design limitations that were not previously available. Additive processes allow increased design flexibility, customization, and complexity. Subtractive processes enable higher production speeds and improved accuracy and surface finish. This paper describes a hybrid system that combines a computer numerically controlled (CNC) milling machine with a high deposition rate polymer extruder to create artifacts using hybrid additive/subtractive processes. Future research plans are described, including possible applications for this system in multimaterial and multi-process manufacturing.
