Update: Here's Version 2 https://www.cgtrader.com/free-3d-print-models/science/engineering/covid-19-face-shield-print-in-just-21-minutes
I have created a face mask that's easily printable on mass scale through stacking and in a very quick time scale. My idea was simple, the main section made in a lattice structure, to save on print time and materials, whilst still retaining the required rigidity for the job.
My design is made up of two simple parts & printable in standard PLA Filament:
Part 1 - AKA the main visor part Made of a lattice structure , which has been designed with the intention of being able to printed one on top of the other, and therefore having the potential to be mass printed even on the smallest of 3d printers (I have used the FlashForge Finder Printer myself). Please see this video https://www.youtube.com/watch?v=MHKBvk8IAc0 by Devin at Make Anything, to see how this is done!
Part 2 - The head forehead support/stabiliser Now this part will not be stackable due to the slight curve for the forehead support, however due to its size can still easily be mass printed and in a very short time (Please Note depending on how accurate your printer is you may need to adjust the notches that fit into Part 1). This part could also be expanded further to provide more support, so feel free to test and adapt.
Part 1: Layer Height - Either 0.2mm, 0.4mm or 0.6mm (Making sure z axis height of part is 3.6mm) Infill: 0% Perimeter Shells: 2%
IF STACKING PRINT MAKE SURE TO APPLY ACCURATE LAYER GAPS
Part 2 Layer Height: 0.2mm Top solid layers: 2
Please note these are the settings for my Flashforge finder printer with a relatively small nozzle, for people with larger scale printers with larger print nozzle setups please feel free to push the settings to its limits, as I believe this could be printable on average in less than 2 minutes with the right settings
I have included as many file types as I can to hopefully mean the most amount of people can edit, improve and print my design. I believe if printed on mass this design could really help cut down on the materials required and time taken to print a face mask. Any questions about my design, just ask and any feedback is appreciated!
Please note. If changing the size of the Visor, be sure to change both part sizes equally in order for them to fit together.
Lastly I'm now currently working on Ver2 of this design, which I hope could be even quicker to print on mass scale, with part 2 being made stackable. I am no expert on stacking prints though, so if anyone has any further ideas or tips, please just let me know.
