在大流行危机情况下，可能会出现严重缺乏防护材料的情况，例如卫生保健专业人员的防护口罩。提出了一个概念验证(PoC)和原型，展示了一种基于材料和技术(3D成像和3D打印)的可重复使用的定制3D打印面罩，可在全球范围内使用。该个性化3D防护口罩由两个3D打印可重复使用的聚酰胺复合材料组件(面罩和滤膜支架)和两个一次性组件(头部固定带和滤膜)组成。计算机辅助设计(CAD)被用于生产基于个人面部扫描的3D面膜的可重复使用组件，这些组件是使用带有两个摄像头和面部扫描应用程序的新一代智能手机获得的。世界各地的CAD设计师可以通过免费下载软件轻松完成3D建模。一次性非织造布熔喷滤膜可在全球范围内从生产FFP2/3防护口罩的工业制造商处购买，用于油漆、建筑、农业和纺织业。使用容易获得的尼龙搭扣作为一次性头部固定带。提出了一种清洗消毒方案。在一个或几个消毒周期后，尚未对3D面罩的可重复使用部件进行泄漏和病毒学测试，这在其在现实生活中使用之前是必不可少的。这一POC应该允许读者考虑在全球范围内制造和/或病毒学测试所描述的定制3D打印口罩。本文描述的两个可复用部件的原始虚拟模板的表面镶嵌语言(STL)格式可以使用超链接(在线补充材料)免费下载。
In the case of pandemic crisis situations, a crucial lack of protective material such as protective face masks for healthcare professionals can occur. A proof of concept (PoC) and prototype are presented, demonstrating a reusable custom-made three-dimensionally (3D) printed face mask based on materials and techniques (3D imaging and 3D printing) with global availability. The individualized 3D protective face mask consists of two 3D-printed reusable polyamide composite components (a face mask and a filter membrane support) and two disposable components (a head fixation band and a filter membrane). Computer-aided design (CAD) was used to produce the reusable components of the 3D face mask based on individual facial scans, which were acquired using a new-generation smartphone with two cameras and a face scanning application. 3D modelling can easily be done by CAD designers worldwide with free download software. The disposable non-woven melt-blown filter membrane is globally available from industrial manufacturers producing FFP2/3 protective masks for painting, construction, agriculture, and the textile industry. Easily available Velcro fasteners were used as a disposable head fixation band. A cleaning and disinfection protocol is proposed. Leakage and virological testing of the reusable components of the 3D face mask, following one or several disinfection cycles, has not yet been performed and is essential prior to its use in real-life situations. This PoC should allow the reader to consider making and/or virologically testing the described custom-made 3D-printed face masks worldwide.
