This Ventilator is an Experimental design done by Mitch Bahneman, a student of Mechanical Design at Chippewa Valley Technical College.
The design intent is to offer a mostly 3d printed, simple machine which will function as an emergency ventilator machine. It uses a basic adult sized BVM(bag valve mask), which are readily available and pumps it as a human hand would.
The electronics are simple and can be obtained for less than 100$.
It is printed in 8 parts and will take roughly 3-4 days, using about 1.5KG of filament.
I used PETG for strength but it might be possible to print in PLA or ABS aswell.
To ensure the most strength I suggest Printing with the following settings:
Ventilator Base
layer height .3mm, line count of 5 at the walls top and bottom. 20-30% cubic infill
Arm Split1 and Arm Split 2
layer height .3mm, line count 4 at the walls top and bottom, 30-40% cubic infill
Pump Base and Bag End dont need to be as strong, Layer height .3mm, line count 3, 20% infill.
Plunger layer height .3mm, line count 4 at the walls top and bottom, 30-40% cubic infill
Short Arm V2 and Lng Arm V2 Need to be strong, Layer height .3mm, 100% infill
Electronics List:
As this is still in the testing phase this list will not be fully complete yet.
