Direct silicone printing has been reported for the manufacture of interim facial prostheses. The recent advancements in printing hardware have allowed for multimaterial simultaneous silicone printing with 4 nozzles. With this technology, an auricular prosthesis was printed with various grades of Shore hardness. A few analog steps, including polishing, sealing, coloring, and relining, resulted in an individualized prosthesis with a thin frontal margin and smooth transition into the adjacent tissue. It was considered a definitive treatment option.

最终硅胶耳廓假体的多材料 3D 打印：一种改进的技术

据报道，直接硅胶印刷可用于制造临时面部假体。打印硬件的最新进展允许使用 4 个喷嘴进行多材料同步硅胶打印。借助这项技术，可以打印出各种肖氏硬度等级的耳廓假体。几个模拟步骤，包括抛光、密封、着色和重新衬里，产生了一个个性化的假体，具有薄的额叶边缘和平滑过渡到相邻组织。它被认为是一种明确的治疗选择。
