Appreciation towards Nagami Design for providing the following description:
专门从事3D打印技术的西班牙设计品牌Nagami design目前正在领导一项旨在加快生产个人防护口罩的计划，以保护当地和全球的医护人员免受COVID-19的侵害。自疫情爆发以来，引起世界震惊的冠状病毒大流行已有超过40万的确诊病例。其中，中国、意大利、美国和西班牙均遭受了最为严重的打击。而在西班牙，尤其是马德里及其周边的省份（如Nagami设计公司的所在地Castilla y Leon），目前也处于十分紧急的状态。
Spanish design brand Nagami Design, which specialises in robotic 3D printing, is leading an initiative to accelerate the production of personal protection masks to protect local and global medical staff against COVID-19. Since its outbreak, the Coronavirus pandemic that is shaking the entire world has registered more than 400.000 cases to date, hitting hardest in China, Italy, the USA, and Spain – in particular Madrid its surrounding provinces such as Castilla y León, where Nagami Design is based.

全球各地的医院都在以超出最大能力的速度运行，在过去几天中，各国对安全医疗设备的需求更呈指数级增长。为了加快口罩和生命支持设备等基本物品的供应，制造商使用3D打印机和其他数字制造工具，通过逐渐形成的全球网络，开始在本地按需进行着生产。Nagami Design目前将其家具生产暂停，转而专注于制造基于Prusa模型的机器人3D打印COVID-19口罩。这种口罩的模型是开源的，可以由台式3D打印机来复制。通过设计一个特定的机器人版本，并借助其挤制加工技术，Nagami Design每天可打印约500个COVID-19口罩（或每五分钟一个），速度比台式3D打印机快约七倍，且能与整个本地社区全天候合作生产。
Hospitals across the global are running at beyond maximum capacity and their need for safe medical equipment has grown exponentially in the past few days. To speed up the supply of essential items such as masks and life support machines, manufacturers are using 3D printers and other digital manufacturing tools, and are forming a global network where on-demand production can be actioned locally. Nagami Design has put its furniture production on hold to focus exclusively on the production of robotic 3D printed COVID-19 Masks based on the Prusa model (www.prusaprinters.org/prints/25857-prusa-protective-face-shield-rc2), which is open source and can be reproduced by desktop 3D printers. By designing a specific robotic version of the model and thanks to its extrusion technology, Nagami Design is printing around 500 COVID-19 Masks per day — or one mask every five minutes — around seven times faster than a desktop 3D printer, and jizhijiagongthe company is working around the clock in collaboration with the entire local community.

“这是迄今为止我们从事过的最重要的、但也是大家希望永远不必开始的项目。我们这一代人拥有真正有意义的知识和数字工具。这种没有产品可以出售、没有市场可以参与竞争的情形，对所有人都是一个挑战。我们希望鼓励所有人使用任何种类的工具来伸出援助之手，为让安全的生活重返世界作出贡献”， Nagami Design的创始人Manuel Jimenez García，Miki Jimenez García和Ignacio Viguera Ochoa说道。
Nagami Design其将目前的工作重点放在工厂所在城市的阿维拉省立医院，并计划在本周扩展到马德里和拉里奥哈等地区。公司收到的订单咨询还来自包括美国、意大利、法国、阿联酋、印度、英国、丹麦在内的其他国家。这些口罩是通过熔融沉积成型法（FDM）来进行生产的，采用的聚对苯二甲酸乙二醇酯（PETG）材料耐用、坚韧、100%可回收，具有很强的抗化学性和抗冲击性。
“This is by far the most important project we’ve ever worked on, but also one we wish we’d never had to start. Our generation has knowledge and digital tools that have become truly meaningful. There is no product to sell, no market to compete in. This is a challenge for all of us, and we’d like to encourage everyone with tools of any kind to reach out and contribute to helping bring safety back into our world”, assert Manuel Jimenez García, Miki Jimenez García and Ignacio Viguera Ochoa, the founders of Nagami Design.
Nagami Design is currently focusing its efforts on Hospital Provincial de Ávila, in the city where its factory is located, and is planning to expand this week to other regions such as Madrid and La Rioja. Inquiries are arriving from various other countries, such as the USA, Italy, France, UAE, India, UK, Denmark, and many more. The masks are produced through robotic extrusion in a layer-by-layer FDM (fused deposition modelling). The material used is a PETG (Polyethylene Terephthalate Glycol) which is durable, tough, 100% recyclable, and has robust chemical resistance and high-impact strength.

“能将生产链减少到最低限度的3D打印已成为本地制造的终极工具。在COVID-19的紧急情况下，该技术为有效生产提供了可负担的工具，而这些工具现在对于挽救生命至关重要。毋庸置疑，这是我们作为设计师和制造商所面临的重要挑战，同时也是对设计直觉和技术的最佳利用时机。” Nagami Design的创始人评论道。
“3D printing has emerged as the ultimate tool for local manufacturing, reducing the production chain to the bare minimum. With COVID-19 emergency, this technology provides the opportunity to efficiently produce affordable tools, which are now essential to help save lives. This is indisputably the most important challenge we have faced as designers and makers, but also the best use of design intuition and technology.” affirm Nagami Design’s founders.
