TL;DR: In addition to face shields, I’m now producing NIH-approved earsavers. Let me know if you need some!
About two weeks ago, I upgraded my old cloggy 0.4mm nozzle to a great 0.8mm nozzle courtesy of Micro Swiss (https://store.micro-swiss.com/). Making this switch greatly increased my printing capacity—when you go from a smaller nozzle to a larger one, the volume of material you can deposit increases by r^2–you reduce both the travel count within each layer, and increase the layer height at which you can print at. This leads to a huge boost in printing speed, with the drawback of losing details. However, for what I’m mass-producing right now, loss in detail is a very minor concern, so cutting my print time nearly in half on one printer is well worth the trade off.
While I continue manufacturing and delivering NIH-approved face shields on one printer, I’ve dedicated my other to the production of NIH-approved earsavers (https://3dprint.nih.gov/discover/3dpx-013759) for the next week or two. These popular devices are great for relieving pressure off the ears of healthcare workers who need to wear surgical masks for hours on end during their shifts. By the end of this week, I will have delivered over 350 of them (including shipments to South Carolina, Tennessee, Oregon, and NorCal!)
Here’s a snapshot of my life for the past few weeks:
Let me know if you or any of your healthcare worker friends need any face shields or earsavers! I’m happy to ship them out.
Again, hope everybody stays safe and healthy out there!
