Default Awesome!

Super cool stuff! If anyone has any tips or tricks for settings and getting good prints, please share them!

You guys are awesome. I was sick (just a cold) last week and wore a mask when I had to go meet someone. I only had it on for a couple of hours, and I thought my ears were going to fall off. This is a wonderful idea.

I've got a batch printing now. I can do five, maybe six at a time on my printer. I've got ABS in there now, but I'll try PLA tomorrow just to save the time it takes to print the brim I have to use to keep the ABS stuck down. As soon as I have a few more done I'll drop them off at a couple of doc's offices and see how many they need.

We reduced cycle time from 17 to 11 minutes by extruding more plastic. changed print width from .6 mm to .9 mm. the straps are fully functional and just as strong. material is ABS. bed temp = 100C. nozzle = .5 mm. no glue on the bed to keep the parts clean.

probably the most important thing you can do is have a calibrated machine. make sure these two things are calibrated before each print or at least at a material change: feed rate from the nozzle (the 100mm test), compensate feed rate for filament diameter (measure filament diameter and set parameters to compensate flow volume).

The variables are near infinite; just as much art as science. Settings will vary with your choice of filament, hardware, software, firmware, and the phase of the moon.

If anyone is running into specific issues I'm sure one of us can help.

Default Laser cutted !!

I can cut this face mask clip very fastly with my laser. One clip take 38 sec. if I use ABS plastic, and only 15 sec. if I use 0.040 cardboard !!

Steve, our group redesigned the ear saver to reduce print time to 6 minutes... I can do 7 in 42 minutes or 10 in an hour (depending on the layout, i'm having better success with the 7-item layout) on my Prusa Mk2.5.

Here's the pattern: https://github.com/bccovid-19/printf...small_V004.STL

The recommended settings we're using in the BCCOVID-19 site seem to work really well: https://github.com/bccovid-19/printf...er/Ear%20Saver

As much as I like the intent behind the "branded" ones (the VA one looks pretty cool in two colours like that), it's been pointed out that it takes longer to print them (so less get made), makes the center of the strap more rigid and less comfortable, and as this is about freely supporting the community nobody should be using it as advertising space. Our group is asking printers to not apply branding.
