As another novelty, the suitability of commercial PCL filaments for producing patient-customized wrist–hand orthoses was also assessed in this study. The 3D printing of PCL and PCL blends is reported mainly for use in scaffold manufacturing or drug delivery applications. UV-B exposure proved to have a significant negative impact on the specimens’ tensile strength. No differences between the failure patterns of the tensile specimens were recorded. The experimental data showed the good repeatability of the manufacturing process, as well as a mechanical behavior independent of the specimens’ infill pattern at full density. Specimens and samples of 3D-printed PCL were analyzed through tensile and flexural tests. gyroid) and ultraviolet (UV-B) exposure over the specimens’ mechanical performances were also investigated to gather relevant data on the process parameter settings for different applications. The influence of the infill pattern (zig-zag vs. In this research, the mechanical properties of 3D-printed polycaprolactone (PCL), a biocompatible and biodegradable semi-crystalline polyester, available as feedstock for additive manufacturing technology based on the material extrusion process, were determined.
