Morakana - COVID - PPE Face Shield

Development of the Morakana face-shield design began after we noticed that the designs we found online either took too long to print or weren’t reusable. This design allows for quicker prints and can partly be reused by detaching the front plastic and putting the headband in the washing machine. The process involves printing a pair of clips, sewing the clips into an elastic headband, and attaching the front plastic to the headband.

Advantages

- Comfortable for long periods of time, no hard surfaces contacting the skin - Reusable headband by sterilizing in washing machine - Minimal design for quick 3D printing (<20 minutes) - Minimal exposed 3D printed area outside shield - Easy assembly on location by healthcare professionals - Only 2-4 headbands required per doctor, then production focuses only on shields Disadvantages

- Requires sewing (20 minutes for a novice)

- PET of 0.007" -0.01" only, anything thinner will be too flimsy - No top cover on this design Requirements

- 3D printer - PET-G filament for 3D printer - Anti-fog PET Sheet - sourced from plastic suppliers - Headbands - off the shelf - Basic sewing kit - Vinyl / laser cutter OR pen knife and cutting mat - Packaging bags and sanitary equipment Procurement Guide for US-based Makers
