Hello I am a Tech Ed Teacher with access to 6 3D printers and a large laser engraver. I was able to download the stl file for the head band and looking to get access to my machines. Thank you in advance as a teacher I tend to ask a lot of questions. 

1. Which material is preferred?  PLA and ABS 

2. How do I print multiple? Should I stack them?

3. How long does the print take? 

4. Preferred infill percent density? 

5. Is there a preset gcode file that can just be printed? 

6. The shield portion. What material am I using? I have a boss laser 24 by 40 bed, which in the settings says I can cut acrylic.

7. What's the preferred thickness for the shield?  

Any help with this will be appreciated.

This is a link to Prusa's model files. All of the pertinent info is there.

To help with some of the questions;

1. PETG seems to be the preferred material as it can be sanitized more easily and has decent temperature resistance.

2. Prusa has provided a link with stacked versions.

3. Stacked versions are: 4 frames = 5h19m  8 frames = 11h6m

4. 30%

5. Yes, provided by prusa

6. Prusa used 0.5mm PETG sheets. Some people are using transperancy sheets for overhead projectors or A4 acetate sheets.

I hope some of that information helps.
