abstract	Additive manufacturing enables the creation of lighter, stronger parts and systems. To improve the 3-dimensional (3D) printed quality of bio-based composites, in this study, 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. The chemical modification was confirmed by spectroscopic analysis; the hydrophobicity, density, and thermal degradation of the fibers were also evaluated. Afterward, 3D-printed objects were produced using these fibers. First, the printability of these composites was assessed by analyzing their melting flow index (MFI) and glass transition temperature (T-g) values. Next, the enhancement of the 3D printing quality was confirmed by analyzing the morphology of the 3D-printed specimens. The advantage of using treated fibers was reflected in the improved mechanical performance of the obtained 3D specimens.
