![]() ![]() During these tests, the plaster cast had the biggest relative change (-79.7%), compared with -4.8 % for the 3D-printed materials. Variable load cyclic tests showed that traditional casts cannot hold the same load at the same deflection after a higher load has been used. In the fatigue tests, the plaster cast and the fiberglass cast did not show normal fatigue curves only the 3D-printed materials did so. The measured values for tensile strength and flexural strength decreased with the increase in CaCO 3 concentration. In addition, cost-effectiveness was evaluated and compared. The materials were characterized by tensile, flexural, Charpy impact, Shore D hardness, flexural fatigue, and variable load cyclic tests, as well as an absorbed water test. The aim of the study was to examine and compare the traditional materials (plaster cast and fiberglass cast) with Polylactic Acid (PLA) and PLA-CaCO 3 composite materials printed using Fused Filament Fabrication (FFF) technology and to produce a usable cast of each material. Three-dimensional printing is a dynamically developing technology which can potentially replace the traditional casts. Traditional cast materials commonly used for treatment have certain disadvantages, including a lack of mechanical and water resistance, poor hygiene, and odors. A total of 17.5% of these fractures occur in the distal radius. Bone fractures pose a serious challenge for the healthcare system worldwide. ![]()
