| Abstract Scope |
This study investigates the development and printability of novel natural carbon-enhanced filament materials. Directly integrating carbon waste (reclaimed coal from mining wastes) as a filler material seeks to reduce the environmental load and cost of fused deposition modeling (FDM) filaments while providing a sustainable and embodied end-use for coal. Carbon filler content ranging from 20 – 50 wt.% was compounded with base polymers of polylactic acid (PLA), polyethylene terephthalate glycol (PETG), polyamide 12 (PA12), and high-density polyethylene (HDPE) to produce natural carbon-plastic composite (NCPC) filaments for use in commercially available FDM printers. As-printed composite structures and carbonized structures provide an environmentally friendly and economically viable alternative for existing materials used in building/construction, tooling, and metal casting applications. The influence of different types and loading of natural carbon fillers on the thermal, physical, and mechanical properties of the resulting composites in traditionally and additively manufactured states will be discussed. |
