Materials (per face shield):
- 40g of PLA Plastic.
- Any glue that can bind both PLA and PET.
- An elastic band.
- An adequately large PET sheet.
- (OPTIONAL) Sandpaper.
- Print the face shield as instructed in the Printing Section.
- Cut the PET visor as instructed in the Cutting Section.
- Assemble as instructed in the Assembly Section.
- The prototype prints were printed on a Creality CR-20 Pro with PLA plastic. Setting changes may be required to print on any other 3D printer.
- 20% Infill
- 0.4mm nozzle
- 0.28mm Layer Height
- 2 Wall Layers
- 4 Top / Bottom Layers
- Supports are required due to the presence of the attachment hooks at the back of the face shield.
- The visor is a 354mm by 200mm rectangular sheet of 1.5mm thick PET sheet .
- It can be Dxf cut however it is not necessary. It can be cut by any means as long as it has the correct dimensions.
- The STL file is to be printed with the groove for the PET sheet facing up.
- It is recommended to sand off the edges of the visor which will not be encompassed in plastic to remove the sharp edges.
- It is not 100% necessary for the PET to be exactly 354mm wide. However, it cannot be any wider as it will not fit in the groove of the 3D printed part.
- The PET sheet may have to be shortened depending on the length of the wearer’s neck.
- Apply glue to the groove on the plastic part and insert the PET visor.
- Wait for the glue to cure completely.
- Apply the elastic band to the attachment hooks.
- NOTE: It may be required to use a longer or more elastic band if the face shield is too tight.
