Nowadays, the clinical use of 3D printing technology is of relevant interest. As confirmed in literature, the applications of 3D Fused Deposition Modeling printing technology in medicine - such as anatomical models and surgical guides - help the clinician in the operations of preoperative planning and surgical simulation. Moreover, the use of 3D printed orthopedic prosthesis/orthosis has been demonstrated to be promising. Albeit the advantages of 3D printed devices, there are still some issues which limits its clinical use, such as the relevant printing and post-processing time. In this regard, the aim of this work is to show how it is possible, thanks to optimizations of the technology and of the process itself, to reduce the printing and post processing time. This can led to a current use of 3D printed medical devices in the clinical courses.
