3D Printing and COVID-19, April 28, 2020 Update
28 Apr, 2020A German firm called LMD Innovation GmbH is 3D printing protective face masks using LUVOSINT TPU from the LEHVOSS Group that meets Europe’s FFP2 and FFP3 filtering standards. FFP2 and FFP3 ratings designate masks that filter at least 94 and 99 percent of particulates, respectively, which can be compared to N95 and N99 standards representing filtration of 95 percent and 99 percent of particulates in the U.S. LMD’s 3D-printed masks fit tightly to the face, as required, and filters can be swapped out. Most interestingly, the masks can be cleaned in the dishwasher. Like WASP’s 3D-printed face mask, these can be tailored to a user’s face using a smartphone app. Unlike WASP’s mask, this device has been certified by the FDA, with the laser sintered TPU capable of meeting the necessary requirements. Once a user’s face is scanned, LMD manufactures the mask to fit.
