Very cool! I did something similar when I designed a functional aortic valve dynamic flow TAVR tester. The hardest part about printing in elastic is the valve leaflets. They are thin and susceptible to tearing. Also, they can stick together. It was a tricky print! Mike -
This is a great post Angel. Initially, need for PPE was focused on hospitals. As business start to open up again, I am seeing increasing demand from office-type facilities like dentists and orthodontists. These businesses have high COVID exposure risk, but don't have the infrastructure like a hospital for obtaining PPE. What innovations exist to fill this unique need?

This is similar to carbon fiber reinforced PLA, which is much stronger than regular PLA. This type of material has the possibility to produce very strong parts. And the concept of fibers that run at different angles can create a much stronger material than even pure PLA, sort of how the layers of plywood give more added strength compared to regular wood alone (see below).

Prusa slicer is not hardware-specific and can be used with most Cartesian FDM printers. For example, there are tons of videos in youtube how to set Ender 3, CR-10, Anet, Tevo and similar low-class printer to work with the full extend of features, which comes with Prusa Slicer. The only issue is the retraction speed - the bondtech gears of MK3 are 3x and the retraction have to be set accordingly. I can't run my Rostock max with it, because it's delta printer and I'm using Cura. Btw, our lab with be updated with Form 2, because of this Aortic valve TAVI simulator - I made the 3D model and ordered it to be printed with Elastic resign on Form 2. The model is excellent, everyone is happy, my lab will get a brand new Form 2 for serial printing of those things... -
