Hamilton 3D Printing Collaboration

The 4th Floor of Central Library is abuzz with the sound of 3D printers creating face shields, face shield frames and ear savers to protect frontline workers batting COVID-19.

The printers come from the City of Hamilton, Hamilton Public Library, Hamilton-Wentworth Catholic District School Board, Hamilton-Wentworth District School Board and Innovation Factory. Further assistance comes from shop3D.

If you’d like to help with this collaborated effort, here are some answers to commonly asked questions.

Q. What material should I use to print?

A. The recommended material is PLA. This has been tested and is the most sanitary.

A. Here's the list:

  • Units are in mm
  • 100% infill
  • No supports, rafts or brim necessary
  • 0.3 mm layer height (for faster printing)
  • 100 mm/sec or higher print speed
  • No need to wait for the part to cool before removing. Hold it in the desired shape for a few seconds after

A. No. The team at Hamilton Public Library, in conjunction with the City of Hamilton, are sourcing these parts.
