Abstract

The recovery, recycling, and reuse of large format additive manufacturing composite scrap material as a secondary feedstock material is essential for large-scale additive manufacturing sustainability. To best understand the feasibility and limitations of recycled feedstock materials for large format additive manufacturing, an assessment of their printability must be completed. This study uses rheological characterization techniques in support of a viscoelastic printability model to evaluate the printability of recycled carbon fiber acrylonitrile-butadiene-styrene (rCF-ABS). The four main conditions assessed to determine the printability of rCF-ABS are: pressure driven flow, bead formation, bead functionality, and component functionality. This study found a 97.1 % decrease in the complex viscosity of rCF-ABS when compared to virgin CF-ABS and found that rCF-ABS satisfied the conditions necessary for pressure driven extrusion flow.
