Emergency mask for hospital respirators

Following some requests, we indicate recommended but not mandatory print settings for the 3D production of 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;

Filament: PLA 1.75 mm

Nozzle temperature: 205 – 210 ° C

Top temperature: 35 – 50 ° C

Layer thickness: 0.2 mm

Supports: only resting on the printing bed.

Orientation: Charlotte resting on the terminal plane (as in the images), Dave resting 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 (it must be able to deform elastically to be able to couple with other components).
