Abstract
This study explores the transformation of beer bagasse, a byproduct of the brewing industry, into a biodegradable composite material for 3D printing. The focus was on developing filaments by blending dried and milled bagasse with polylactic acid (PLA) and epoxidized soybean oil (ESBO) as a plasticizer. Multiple compositions were tested to evaluate the influence of bagasse and plasticizer ratios on the mechanical properties and printability of the final material. The optimal filament (80% PLA + 20% BG) was printed using a Creality Ender 3 V3, demonstrating the potential of upcycling agricultural waste into functional additive manufacturing materials.
