3D Face Shields: Improving printing time and quality

A collection of posts about DIY/Open Source PPE is here.

You can help support this, even with no money.Thanks


There are two videos here at present. I will continue to add references when I can. No one is endorsing me nor sponsoring me.I get no percentage of anything bought through these links;I am sharing them for efficiency only.

The bottom line is that once a face shield is on the face of someone, it can be a life or death situation. Brittle shields, shields that can fall off, shields that are uncomfortably tight: these issues and more we want to avoid.

Faster printing times are counterproductive and dangerous if they break.

Cheaper filament may allow for more to be made, but QUALITY CONTROL must be a constant.

Would you wear your faceshield in a situation where it was needed most?


The following are notes that will be better organized in the future. My hope is that these fragments can answer questions, save time and prevent problems. THANK YOU


The Jai14 mask is flexible and has been tested. 14 minutes printing time.


(For the very first time, the time to make one mask is 3 hours, meaning loading of models, setting up profiles etc. Once these are done for the first time, the following prints will take much less time to make. USEFUL INFO STARTS 2 minutes into the video.)

In this video I'll go through what settings to change to really speed up your 3D Printing. This is particularly aimed at newcomers to 3D printing who are starting to 3D Print face shields to battle the COVID-19 outbreak. Please note that Maximum speed isn't always optimal! Make sure you provide good 3D Prints that are accepted. - - - - - - -

COVID-19 has halted my consulting services and I have little to no work, which is very bad when you're self-employed and can't take part of regular social services.

The following are condensed from the comments:

  • this is a CURA version. I have a 0.8mm nozzle and came here struggling to make it print with cura at 0.6mm layer height. From your video its evident that the most I can push it is 0.5mm. My challenge is the seam line. It raises between layers at higher layer heights.

  • Got 25min on MK2.5S with 0.4mm nozzle on 0.35 layer
  • We print stacks of them at 17min a piece with just a 0.4mm nozzle. We redesigned them to make them stronger (chambered walls to stack the layers like a brick wall), faster (smaller top and bottom surface) and better stackeable/splittable (also due to the smaller top/bottom surface). On top of that, PrusaSlicer does a better job at faster/more logical gap fill. Our remix of the faceshield is downloadable at MyMiniFactory (A better and faster stackeable visor/faceshield)
  • I just print your model and is great! 19 min, now going to test 36x stack Thanks.
  • Ender 3s can get issues trying to push out large volumes of filament at once. If you see too little is coming out, dial back on speed and/or increase temperature on extruder 5-10 degrees (c)
  • How would I use the Prusa Slic3r software to get the same time savings? Start with changing layer height, as it affects much. Depending on the model you're printing, maybe you can adjust infill/shells/walls as well, but dont "overdo" it. Make sure your model is acceptable before pushing it too far! When you say change layer height, would you change it up or down? Up.So as standard with a stock Prusa I3 (for example) you have 0,4mm nozzle. The general rule is that you can go up to 0,3mm layers with that nozzle. If you're printing at 0,15 or 0,2mm today, try test it in 0,05mm steps. So start with 0,2 or 0,25 before hitting 0,3 and see the difference in results. Sometimes you can have difficulties getting first layer to stick with higher thicknesses, so just monitor your printer when it starts.
  • Increase the Travel speed to 300 mm/s most machines can easily do it.
  • To visualize color: When you press slice (or if you have auto-slicing on) you can select in top-right corner of the 3D-view and choose Layer view. As default, it should say "Solid View".

I started printing face shields for a local initiative. This is the workflow that I used to optimize the printing speed. I was able to reduce the printing time from 5 hours with my standard parameter to less than 1 hour with the optimized one!
