Printed on Prusa i3 MK2S

Reference Model 

We have successfully printed headbands on the Prusa i3 MK2S printer in both PLA and PETG.  At 0.25mm layer height, printing two face shields takes 6hr30m.  Adjusting the layer height to 0.35mm reduces the print time to 4h15m, but there is some sagging in the top of the visor.

Recommended Material: PLA or PETG/CPE
Alternate Materials: ABS, ASA or Nylon

  • Part Parameters for 3D Printing
  • Layer Height: 0.25mm
  • Wall Thickness/Shell Thickness = 1.2mm minimum (3 perimeters or shells)
  • Top/Bottom Layer Thickness = 0.8mm minimum
  • Infill Density = 30% minimum (commnet should it be 100% infill, less risk of absorbing chemicals if we do have to soak frames, build time increase is minimal)
  • Infill Type = Line or Grid
  • Platform Additions /Build Plate Adhesion: Raft or brim as needed. Note: Do not use commercial grade bed adhesives like “MagiGoo” since skin contact reaction/sensitivity is unknown. PVA/Glue stick may be used, residue shall be washed off part during post processing
  • Support: Not Needed

Additional Notes:

  • Regardless of the printer or slicing program you are using it is always recommended to be using the most up to date firmware on your printer and the most recent version of your slicing program.  This will only help if you need the community to troubleshoot any printing issues/questions you may have.
