I print at 50mm/sec (fairly low jerk settings though), 0.3mm layer height with a 0.8mm nozzle. Even with ABS (at 260C) layer adhesion is great. My kids tried it on and roughandled the shields in the process, and they stood up to all the abuse.

This is ingenious! I love how you utilized complaint mechanism to maintain tension on the face shield as opposed to using elastic or velcro! This would significantly lower the cost, and speed up production!

Thanks! Given that my printer, an Ultimaker 2, can print one in 11 minutes, a group of volunteers with 50 printers between them can make over 250 of these an hour, or 2,500 in ten hours. It's not a lot, but useful for a local hospital who wants disposable face shields.

Wow that's awesome! Yes 2500 in 10 hours isn't a lot compared to the demand, but still that's amazing for additive manufacturing! 1 in 11 min is pretty impressive too! What layer height would this work up to? Guess draft quality (0.3 mm) could still work with good layer adhesion yet boost production?
