Universal Covid-19 Face Shield

3D model description

NEW version!

  • Optimized for faster production. Can fit 4 units in a 20x20x20 bed or 6 units in a 21x25x20 bed (Prusa models).

  • Use it as a ruler: measure de size of an A4 sheet with the marks on the model to use any piece of bottle or acetate you have. Also, we've marked were to make de cut for the acetate/bottle to hold in place.

New version!

  • Optimized for increased production. Can fit 4 units in a 20x20x20 bed or 6 units in a 21x25x20 bed (Prusa models).

  • Use it as a rule: you can measure the size of an A4 sheet with the markings on the model to use any bottle or acetate part you have. Also, we have marked where to make the cut so that the acetate/bottle stays in place.


Universal Face Shield optimized for maximum production. Easy to print, no supports needed, ultra-fast print ( with nozzle 0.6mm in 12min), adaptable to aný cut bottle/acetate sheet/Xrays/etc you can find, for day-to-day use (only for those who fulfill NECESSARY services #stayhome . 3dprints are not particle proof. Covid-19 can live in the plastic surface up to 4 DAYS)


Universal Face Protection optimized for maximum production. Easy to print, no media, ultra-fast printing (peak 0.6mm in 12min), adaptable to any trimmed bottle/acetate sheet/radiography/etc you can get, for day-to-day use (only for those who fulfill NECESSARY services #stay indoors. 3d prints are not particle proof. Covid-19 virus can live on plastic surfaces for up to 4 DAYS)

IMPORTANT

As we all know, 3d prints are NOT particle proof, so, the less material, the easier to sterilize, and less probability to carry the covid-19.

Also, we need to optimize production: this means optimizing processes and eliminating unnecessary logistics. For example, one version of a face shield can require 60-120min of 3d printing (depending on the remake), 30min of laser cutting + logistics + 10min assembly. This is:

70 x week x Maker (16 hours working) vs 224 x week x Maker


IMPORTANT

We all know that impressions are not particle-proof, so the less material, the easier it is to sterilize, and the less likely it is to transport the covid-19.

In addition, we must optimise production: this means optimising processes and eliminating unnecessary logistics. For example, a version of a face shield may require: 60-120 minutes of 3D printing (depending on the new version), 30 minutes of laser cutting + logistics + 10 minutes of assembly. That is:

70 x week x Maker (16 hour day) vs. 224 x week x Maker


IF YOU HAVE a laser cutter or CNC, etc, there is NO NEED FOR a 3D printing part. Fully functional model available below!

IF YOU HAVE a laser or cnc cutting machine, etc., THERE IS NO NEED for a fully functional model available below!
