Both face masks were tested on the same two volunteers. The customized 3D-printed face mask presented a higher adaptation compared with the conventional face mask. The area of facial contact matched the one digitally designed in the software.
The 3D-printed grid could clip exactly into the filter, which in turn could be precisely screwed into the body of the face mask. Within the limitations of this technical report, the present findings suggest that customized 3D-printed face masks with enhanced adaptation can be digitally designed using face scans and free CAD software. Rationale and Objective: 3D printing allows innovative solutions for personal protective equipment, particularly in times of crisis.
