I am currently printing in Grey standard resin. The print is around 68 ml (for one complete face shield) so at 160 micron height the print time is around 7 hours. I am able to fit 4 half face shields (https://3dprint.nih.gov/discover/3dpx-013523) on one build platform. That print time for two complete face shields (full build platform) is around 13 hours. I have been looking at possibly switching to draft resin, if I did that the full build platform print would be around 5 hours.
This design was made for entry level FDM printers. I am printing the design being it was approved by NIH. By printing with the Form 3 the part cost way more than if it was made with FDM filament but it is also smooth and completly solid so it can be cleaned and sanitized. Whereas the FDM can be harder to clean and sanitize.
Being the face shield bracket, that is being 3D printed is not a biocompatible resin it is not advised to be in contact with skin. To produce this part without having to use Dental SG (double the cost of Standard resin) I am using a thick closed cell foam in the brow area. This will hold the bracket away from skin contact as well as being closed cell foam will be able to be cleaned and sanitized.
