Low energy mass manufactruing of PPE using visible light 3d printing

covid - 19危机表明，缺乏个人防护装备和合适的医疗设备如何导致全国性的卫生危机。这个项目的目的是创造一个可持续的和通用的解决方案，以解决过去6个月经历的制造业短缺。这将使英国拥有自己的国内制造业弹性，完全由可再生能源制造。最近大量使用个人防护用品正在造成生态问题，因为数以千万计的一次性塑料正在以惊人的速度被丢弃。该项目旨在解决短缺和可持续性问题。英国一家名为Photocentric的公司发明了利用LCD屏幕制造3D打印物体的技术，利用低能量可见光选择性地固化光聚合物。这一概念已成功商业化与制造大幅面工业3D打印机在彼得伯勒制造。Photocentric现已通过为NHS生产近200万个面罩，验证了在这场危机期间大规模生产个人防护装备的有效性。该项目将优化这一过程，使其能够在需要的时候转移到无限数量的不同项目。该过程将实现自动化，可以作为移动3D打印工厂在集装箱中交付，用于在需要时制造个人防护装备和医疗设备。该工艺中使用的3D打印树脂将在英国开发和制造，使用100%可持续资源，其中包括30%的回收材料。综上所述，该项目采用低能耗LCD屏幕3D打印技术，采用英国制造的100%可持续材料，实现了PPE和医疗设备的低成本、快速和多功能制造。

The Covid19 crisis has shown how the lack of PPE and suitable medical equipment can lead to a national health crisis. This aim of this project is the creation of a both sustainable and versatile solution to the manufacturing shortage experienced in the last 6 months. It will enable the UK to have its own domestic manufacturing resilience, which is entirely made from renewable sources. The recent large usage of PPE is creating an ecological problem as tens of millions of single use plastics are being thrown away at an alarming rate. This project will aim to address both problems of shortage and sustainability.Photocentric, a UK company, invented the using LCD screens to create 3D printed objects using low-energy visible light to selectively cure photopolymer. This concept has been successfully commercialised with the manufacture of large format industrial 3D printers made in Peterborough. Photocentric has now validated the mass-manufacture of PPE during this crisis by manufacturing nearly 2 million face shields for the NHS. This project will optimise this process to enable it to be transferred to make an unlimited number of different items at a time of need. The process will be automated and can be delivered in a shipping container as a mobile 3D printing factory for the fabrication of PPE and medical devices at the point of need. The 3D printing resins used in this process will be developed and manufactured in the UK, using 100% sustainable resources including 30% recycled materials.In Summary, this project enables low-cost, rapid and versatile manufacturing of PPE and medical devices using low energy LCD screen 3D printing with 100% sustainable materials form UK derived technology, made in the UK.
