摘要： Proposed are a composition for an eco-friendly filament using soybean hulls and a 3D printing eco-friendly filament manufactured by using the same. A manufacturing method of the 3D printing eco-friendly filament by using soybean hulls includes a first step of manufacturing soybean hull powder by grinding the soybean hulls, a second step of manufacturing a composition for an eco-friendly filament by adding biodegradable plastic resin to the soybean hull powder and mixing the biodegradable plastic resin with the soybean hull powder, and a third step of manufacturing the 3D printing eco-friendly filament by cooling the composition for an eco-friendly filament after extruding the composition for an eco-friendly filament through an extruder for filament formation. The composition for a safe and eco-friendly filament while discarded soybean hulls are used for resource utilization and the 3D printing eco-friendly filament manufactured by using the same are provided.
