Following some requests, we  recommend some print settings (not mandatory) for the 3D production of the Charlotte and Dave components for the assisted breathing mask. For the production of these pieces, since high precision is not required, an FDM filament printer with "basic" settings is more than sufficient;
PLA filament 1.75 mm
Nozzle temperature: 205 - 210 ° C
Builtplate temperature: 35-50 ° C
Layer thickness: 0.2 mm
Supports: only touching the builtplate.
Orientation: Charlotte leaning on the terminal plane (as shown in the images), Dave leaning on the larger diameter vertically.

As for the printing material, we recommend the most common filament on the market, the PLA (polylactic); this for several reasons:
Odorless (remember that patients must breathe air passing through these components)
The least dangerous possible (PLA is not very dangerous and biocomposable)
Relatively flexible (must be elastically deformed to be coupled with other components).
