Face shields – Models and variants – analysis

So far have 3d printed 3 variants of faceshields. I’ll try to compare them. If you have feedback please add it to comments section below. So let’s start

Let’s compare them:

Time to print (min)Number printed in 1 runMaterial (g)
Model 1102255.4
Model 2100250
Model 360 233
Comparison between models

So. If need to produce a lot of them Model 3 seems to be the way to go.

Model 3 – verkstan:

Advantages:

  • You can use 0.15 mm transparent A4 sheets ( or A3 sheets ( we had a request for a larger shield to protect also a part of the chest ) )
  • No need for elastic band
  • Easy to make the holes
  • Easy to assemble
  • Fast print

Disadvantages:

  • Less sturdy than M1 or M2
  • Are not adjustable vertically ( this is a strong point for M2 )

Model 2 – Timisoara

If you need to be able to adjust vertical length of the transparent sheet this is the way to go.

Advantages:

  • Easy to use
  • Easy to change transparent sheet
  • No holes necessary
  • Works with both PETG and A4 transparent sheets

Disavantages:

  • Slower print time

Model 1 – Prusa

De facto standard when comes to open 3d printed face shield

Advantages:

  • Very good production standard
  • Easy to assemble

Disadvantages:

  • Requires PETG sheets to be laser cut ( there are some tests to adapt A4 sheets to them but holes are hard to do )
  • Requires elastic bands .

No matter what model is used, they all keep our doctors safer. So far we printed , manufactured and donated around 200 of them. Below some pictures from the field:
