Emergency mask for hospital respirators
thingiverse
Following some requests, we provide suggested but not required print settings for 3D production of Charlotte and Dave components for the assisted breathing mask. For producing these pieces, since high precision is not necessary, an FDM filament printer with "basic" settings is more than enough. 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, PLA (polylactic); this for several reasons: Odorless (remember that patients must breathe air passing through these components) The least hazardous possible (PLA is not very hazardous and biodegradable) Relatively flexible (it must be able to deform elastically to couple with other components).
