| Abstract Scope |
To progress toward a circular economy of thermoplastic polymers using distributed recycling by additive manufacturing, the mechanical degradation of polymers through multiple recycling cycles must be quantified. This work presents a procedure and benchmark dataset of tensile property degradation for polylactic acid (PLA) feedstock in multiple recycling passes with the fused granule fabrication process. To establish recycling with minimal processing (shredding and sieving but not pelletizing from a filament), modifications were required to the granule feeding hopper of the GigabotX 2 XLT printer. Tensile test coupons are die cut from machined sheets from a vase-like 3D printed tube shape. Tensile properties are presented for 3D prints of the virgin material and one, two, three, and four passes of recycling by additive manufacturing. |
