An efficient 3d printed face shield for the covid 19 effort. Designed to prove a distributed model. Batch.works is a sustainable 3D printing designer and manufacturer, based in London. One of their products is the Batch.shield visor, designed in 2019 and distributed widely during the coronavirus pandemic. Batch.works came about because founders Vaissieres and Mcloughlin-Greening wanted to develop an alternative to centralised manufacturing, by using 3D printers. Batch.works abide by the ethos of producing locally, so that materials can be easily tracked as they enter and leave the factory. They also repurpose materials, avoid landfill and generate minimal waste. The Batch.shield project has become an exciting flagship for distributed manufacture moving from theoretical ideas directly to a working example. Batchworks have proven that an inner city manufacturing hub can pose a realistic alternative to imported mass manufacture.
