Congress contribution by Sepideh Hatamikia Sepideh Hatamikia participated in a research project entitled "3D-Printer Enabling Customized Anatomic Models" presented at the 27th Congress of the European Society of Biomechanics (ESB), June 26-29, 2022, in Porto, Portugal. An emerging technology in additive manufacturing is extrusion-based silicone rubber 3D printing, which allows customizing the mechanical and radiological properties of printed objects. The capabilities of a custom-built 3D printer were investigated. This printer has three printer heads, two of which can print with viscous liquid materials and one with thermoplastic filaments, in the same printing process. It was shown that changing the degree of filling of the printed silicone objects affects the mechanical and radiological properties of each object macroscopically. Therefore, this method could be useful for producing more realistic 3D-printed anatomical models for medical education, research, and preoperative planning.
