This is version 2 of my 3d printable face shield design. Please see version 1 here https://www.cgtrader.com/free-3d-print-models/science/other/covid-19-3d-printable-face-shield-by-modesigns

The Key Features are

21 minute print time at 0.20mm layer heightStack-able design meaning ability to print 100+ masks in one print Strong lattice design requiring minimal print materialPrinted successfully in PLA

This new and improved version has more support, whilst being even quicker to print. It only take 21 minutes per print and this can be reduced to around 18 minutes per print when printing on mass.

Part 1 - The main visor part Made of a lattice structure, which has been designed with the ability to be 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 & Creality CR-10 Printers myself). Please see this videohttps://www.youtube.com/watch?v=MHKBvk8IAc0 by Devin at Make Anything, to see how this is done!

Part 2 - This part is now stackable, but only when setup correctly with both the flat piece and then stack-able version above. (both files are available within the stl, fbx, obj and blender files. Just make sure that there are 2 layer gaps between each, so 0.4mm)

Print Settings:

**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: 2Top & bottom solid layers: 2

IF STACKING PRINT MAKE SURE TO APPLY ACCURATE LAYER GAPS AND TEST PRIOR TO PRINTING A LARGE AMOUNT. PART 2 ESPECIALLY NEEDS TO BE SETUP EXACTLY RIGHT AND WILL STILL BE A LITTLE CHALLENGING TO SEPARATE

Part 2Layer Height: 0.2mmInfill: 0%Perimeter Shells: 2Top & bottom 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 Part 1 could be printable on average in far less time 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 printed design, be sure to change both part sizes equally in order for them to fit together. Also you will need to take into account the position of the holes will also be different
