WTCC’s 3D Printing Initiative
WTCC’s 3D Printing Resources
For those who want to join us on our 3D printing initiative, we’ve prepared a packet to outline our guidelines for printing PPE:
Once you’re ready, we encourage you to use the following submission form to join our team on our efforts to bring PPE to hospitals and medical clinics across Wyoming who have an urgent need for PPE:
And finally, don’t forget to track where you stack-up to the rest of the WTCC 3D printing team by seeing where you line up on the WTCC 3D Printing Dashboard!
Requests for PPE
Among the projects supported by donations to WTCC are our volunteers’ efforts to create Personal Protect Equipment (PPE) for hospitals, medical clinics, and other organizations throughout Wyoming. Costs associated with the 3D printing of PPE include:
- Purchasing 3D printer filament, PETG sheets, laminate, and similar materials
- Shipping expenses related to the procurement of PPE assembly materials
- Shipping expenses related to the delivery of completed PPE to hospitals, clinics, and other organizations throughout Wyoming
A Few Words on 3D Printing
Some interesting facts on 3D printing PPE:
- Most of the machines used for 3D printing cost a few thousand dollars each.
- Prior to printing, 3D models of the PPE masks are arranged in such a way that multiple masks can be printed at the same time within one 3D printer.
- Before printing the actual mask, a “raft” must be printed onto the build platform of the 3D printer. This is an initial layer of printed filament which forms a horizontal mesh that supports all additional layers of the filament which are printed to form the mask itself.
- While printing, a machine operator periodically reviews progress ensure there are no issues with the printer or the spool of filament feeding into the printer.
- Once a mask has been printed, it must go through a general review for accuracy as well as an extensive post-processing stage. Typical post-processing steps include:
- Removing the raft layer from the base of the mask
- Removing bits of filament that may be causing undesirable rough edges
- Smoothing of the material on the mask surfaces and edges
- For some special requests, mask surfaces are washed with acetone prior to delivery to ensure a smoother surface.
