Introduction: Face Shield for Covid-19 Frontliners | Version 1.1
Due to the shortage of Personal Protective Equipment (PPE) for those working in the front-line amidst the Covid-19 outbreak, we thought it would be best to share a collaborative design for a fast and efficient protective face shield that could be easily replicated and mass-produced. In our search over the past few days we have found that 3D printed parts, although highly effective, cannot be produced fast enough to meet with the current demands globally.
It is our hope that products such as this can be reproduced around the world through rapid prototyping for those who are in dire need of it. This initiative is the result of a request by our friends in the medical sector who have expressed a need of about 30 thousand units per month of this face shield due to the outbreak. Please follow the steps below and make sure to share with others that may have the capacity to build the protective face shields too! Supplies: 1) Acrylic sheets (preferably 4mm or 5mm thickness) 2) A4 sized transparent PVC rigid sheet (0.2mm) 3) Sponge or EVA / PU Foam equivalent 4) Scissors and cutters 5) Hot glue gun + Glue sticks 6) Elastic bands (the kinds used for tailoring) or equivalents such as Household rubber bands 7) Laser Engraving Machine (in our case we use the Epilog Helix 75W)
1) Acrylic sheets (preferably 4mm or 5mm thickness)
2) Di cut PVC Sheet 0.3mm (430mm x 470mm)
4) Hot glue gun + Glue sticks
5) Elastic bands (the kinds used for tailoring) or equivalents
7) Laser Engraving Machine (in our case we use the Epilog Helix 75W)
Step 1: Preparing Materials
1) Laser cut the acrylic piece using our open source design file
2) If you are not provided with the Di Cut PVC, you will have to create a mold using our design and get PVC pieces as they are vital in our design
3) Prepare a hot glue gone (optional) and a cutter
4) Watch attached video alongside to ensure you are following the steps
Step 2: Removing Excess Plastic
1) Remove the plastic sticker from both sides of the acrylic piece
2) Remove excess plastic from PVC, The cut will have created holes for you to take out
Step 3: Bend the Top of the PVC
Using the guided lines, create a bend on the PVC to create a 90% angle
Step 4: Slide Slits Into the Locking Mechanism on the PVC
1) The wider section of the PVC will have multiple slits that will fit into the bent side of the PVC.
2) Connect and lock all slits into their respective holes and ensure you bend the excess slit to secure
4) Here you may choose to use the glue gun to further secure this slit
Step 5: Attach Acrylic Piece to PVC and Attach Foam to Inside of Acrylic Piece
1) The outer part of the acrylic will have multiple extruding pieces that fit into the inside of the PVC. Attach all pieces to ensure a secure fit. Watch the video for clearer instructions.
2) Attach the foam to the slit in the inside face of the acrylic piece.
Step 6: Attaching the Elastic
The elastic can be attached to the hooks at the end. You are able to choose how tight or lose you want the Face Shield to fit.
