Ultra-fast design and production of custom-fitted reusable FFP2/N95 face masks: combining 3D face scanning and 3D printing technologies (UFM3D)

ActiveCell Technologies是一家位于利兹的初创企业，它正在开发一种颠覆性的产品，用于使用熔融沉积技术进行快速原型制作和制造-这是一种3D打印农场，任何物品都可以立即发送打印并进行远程监控。在UFM 3D项目中，ActiveCell将开发一种创新工艺，用于快速设计和制造可重复使用的N95/FFP 2过滤面罩，以解决1）目前一线工作人员的呼吸机短缺，反应灵敏，规模大2）所述呼吸机的面部拟合问题。ActiveCell Technologies将开发一款移动的应用程序，能够生成用户面部的3D扫描，后端软件自动处理这些数据，将其转换为呼吸器3D打印的模型。它还将根据同行评审的已发表设计开发和测试呼吸器。在全面实施该服务之前，将在6个月内生产100个单位，并在NHS的前线工作人员中进行测试。从长远来看，NHS和公众将可以按需生产完美贴合的过滤口罩。扩展：鉴于最近政府指令要求所有人在公共场所必须戴口罩和面罩，对我们的可重复使用的N95/FFP 2面部贴合过滤口罩的需求预计将高于最初的预期。为了能够满足这一需求，我们需要通过自动化流程来改进和优化我们的生产运营，从接收订单到成品包装和地址标签。我们打算设计和开发一台全自动机器的原型，使我们能够联合收割机将我们现有的两到三台设备结合起来，从而有可能达到每天350到400个口罩的生产率，是我们目前生产能力的两倍。

ActiveCell Technologies is a Leeds-based start-up developing a disruptive offering for rapid prototyping and manufacturing using fusion-deposition technology -- a 3D-printing farm where any item can be sent to print instantly and monitored remotely.In project UFM3D, ActiveCell will develop an innovative process for the rapid design and manufacture of reusable N95/FFP2 filtering masks to address 1) the current shortage in respirators for frontline workers, responsively and at scale 2) the issue of face fitting of said respirators.ActiveCell Technologies will develop a mobile app able to generate a 3D scan of the face of the user, and the back-end software to process this data automatically to convert it into a model for the 3D-printing of a respirator. It will also develop and test a respirator, based on a peer-reviewed published design. 100 units will be produced within 6 months and tested with frontline workers at the NHS, before the full implementation of the service.In the longer term, a service for on-demand manufacturing of perfectly fitted filtering face masks will be available to both the NHS and the general public.Extension: Given recent government directives making face covering and masks mandatory for all in public spaces, demand for our reusable N95/FFP2 face-fitting filtering masks is expected to be higher than originally anticipated. To be able to answer this demand, we need to improve and optimise our manufacturing operations by automating the process from the point of reception of an order, up to packaging and address-labelling the finished product. We intend to design and develop the prototype of a fully automated machine that would enable us to combine two to three of our current devices, making it possible to reach a production rate of 350 to 400 masks per day, twice what we are currently able to produce.
