This paper explores developing sustainable 3D printing filaments using organic soybean hulls mixed with polylactic acid (PLA). The study experiments with various particle sizes and mixing ratios, examining the physical and mechanical properties of the resulting filaments. Results show that smaller soybean hull particles and specific mixing ratios enhance the filament's quality while maintaining PLA's characteristics. This research signifies a step towards environmentally friendly 3D printing materials, offering a viable alternative to conventional filaments and addressing ecological concerns in the industry.
