Abstract:

Large-scale thermoplastic extrusion-based 3D printing, also referred to as additive manufacturing
(AM), has shown promise for a multitude of applications in civil infrastructure. Advancements in this
technology have led to increased usage and a subsequent increase in generated waste. Recently, the
opportunity to recycle this material has contributed to lessening this waste. Presented in this work are
established baseline thermo-mechanical and physical properties of carbon fiber acrylonitrile
butadiene styrene (CF-ABS) and wood flour amorphous poly lactic acid (WF-aPLA). Additionally,
this work is to be used in comparison with subsequent recycling cycles in evaluation of the
mechanical recycling process for large-scale 3D printed CF-ABS and WF-aPLA with intended
applications as formwork for precast concrete.
