鉴于当前新冠疫情大流行，使用高质量口罩是必不可少的。这项研究提出了一种全自动技术来设计面部特定的面罩。通过使用立体摄影测量、计算机辅助设计和三维（3D）打印，我们描述了一种完全适合个人面部特征的制造面罩的协议。将面部专用面罩与通用设计的面罩进行比较，并将不同过滤容器的设计与面罩主体合并。对面部专用面罩的主观评估表明，鼻子、嘴巴和下巴区域紧密闭合，并且允许正常佩戴眼镜。建议使用螺丝驱动锁定系统，以便轻松组装过滤器组件。该过程的自动化可以实现大批量生产，但仍然允许设计师进行足够的互动来满足特定要求。与一次性标准化面罩相比，建议的方案可用于提供更舒适、有效和可持续的解决方案。后续对印刷材料、灭菌技术和国际法规合规性的研究将有助于将面部专用口罩引入临床实践和一般用途。
The use of high quality facemasks is indispensable in the light of the current COVID pandemic. This study proposes a fully automatic technique to design a face specific mask. Through the use of stereophotogrammetry, computer-assisted design and three-dimensional (3D) printing, we describe a protocol for manufacturing facemasks perfectly adapted to the individual face characteristics. The face specific mask was compared to a universal design of facemask and different filter container’s designs were merged with the mask body. Subjective assessment of the face specific mask demonstrated tight closure at the nose, mouth and chin area, and permits the normal wearing of glasses. A screw-drive locking system is advised for easy assembly of the filter components. Automation of the process enables high volume production but still allows sufficient designer interaction to answer specific requirements. The suggested protocol can be used to provide more comfortable, effective and sustainable solution compared to a single use, standardized mask. Subsequent research on printing materials, sterilization technique and compliance with international regulations will facilitate the introduction of the face specific mask in clinical practice as well as for general use.
