To improve the 3-dimensional (3D) printed quality of bio-based composites, bamboo fibers were chemically modified via a two-step reaction. In the first step, NCO groups (of a diisocyanate) were grafted onto the surface of fibers, which were subsequently reacted with a polyol. Afterward, 3D-printed objects were produced using these fibers. The advantage of using treated fibers was reflected in the improved mechanical performance of the obtained 3D specimens.
