The artistic techniques necessary to fabricate facial prostheses mainly depend on individual skill and are not a resource easily reproduced. Digital technology has contributed to improved outcomes, often combining analog and new digital techniques in the same workflow. This article aims to present an innovative workflow to produce a final colored 3D printed and facial prosthesis by UV-map color translation into colored resin 3D printing. A modified +ID Methodology was used to obtain 3D models with the calibrated 3D printable patient's skin color. No hands-on physical molding, manual sculpture, or intrinsic silicone coloration was used. The outcome resulted in acceptable aesthetics, adaptation, and an approximate color match after extrinsic coloration. The patient reported good comfort and acceptance. A direct resin 3D printed prosthesis may be a viable alternative, especially for rapid delivery as an immediate prosthesis or an option when there is no experienced anaplastogist to manufacture a conventional prosthesis.
制作面部假体所需的艺术技巧主要取决于个人技能，并非易于复制的资源。数字技术有助于改善效果，通常在同一工作流程中结合模拟和新的数字技术。本文旨在介绍一种创新的工作流程，通过将UV映射颜色转换为彩色树脂3D打印来制作最终的彩色3D打印面部假体。使用改良的+ID方法获得具有校准的3D可打印患者皮肤颜色的3D模型。未使用手工物理成型、手工雕刻或内部硅胶着色。结果在外部着色后具有可接受的美学效果、贴合度和近似的颜色匹配。患者报告舒适度和接受度良好。直接树脂3D打印假体可能是一种可行的替代方案，特别是对于作为即时假体的快速交付，或者在没有经验丰富的整形修复师来制造传统假体的情况下作为一种选择。
