![]() ![]() Subsequently, the patient wore the brace in a pilot case to compare comfort and mechanical effectiveness. The model was then printed as a single piece and postprocessed by an expert orthotist. The thermoformed brace of a volunteer patient affected by scoliosis was reproduced using reverse-engineering techniques. ![]() Moreover, a cost analysis was carried out for the specific application. Printed samples were analyzed with electronic microscope, tensile, and impact tests and compared with thermoformed polyethylene (PE) and polypropylene (PP) samples. Polyethylene terephthalate glycol-modified (PETG) was selected among the several filaments materials present on the market. ![]() Critical parameters, such as manufacture time, mechanical properties, weight, and comfort are carefully considered. This work evaluates the feasibility of producing orthopedic scoliosis braces by 3D printing, comparing performance and costs with classical thermoforming procedures. In recent years, 3D printing gained considerable attention in the orthopedic sector. ![]()
