Glowforge laser cutter owners made over one million "ear savers" for hospital mask wearers

I love this story. I work at a University in BC, and after we had collected and donated all of our reserves of smocks, rubber gloves and face masks we went on a 3D printing and laser cutting spree to produce face covers (laser cut from PETG… very smelly/fumey), and lots of ear savers. We had to 3D print those because we couldn’t get our hands on anything thin/flexible to lasercut.

The next round, I want to see instructions for 3D printing moulds.


This is cool. Decentralized Disaster Recovery.


I get what you mean, but I think centralized disaster recovery is a recipe for disaster anyway.


This is a great idea. I can’t wear those masks because they hurt my ears too much.

This is the kind of thing that should be lauded by our leaders. Help your fellow humans!

What should not be congratulated is re-opening your state only to have to shut it down again in two weeks when health care workers (the real heroes nowadays) start getting sick.


3d print a set of positives then use them to create a silicone mold, I think. ( also work with metals: instead of lost wax we use lost PLA method )

Where do the materials for these efforts come from? If everyone is buying styrene sheet stock at retail prices then this is not “mass production” or a rosy Diamond Age future. This is just throwing away all efficiencies of scale and everything would cost 10x more if made this way. Not to mention this would be a gig economy piecework nightmare in any non-pandemic scenario.

It’s great that hipsters with toy laser cutters are able to help out in this crisis, but let’s not lose our heads extrapolating this as a revolution in manufacturing. It’s a desperate move in desperate times and that’s all it needs to be.
