given the sensors and interface hardware is easily controlled via a RAMPS 1.4 setup

So the only other piece that needs to be used is a moth-nose adapter to keep the pressure in

yes, yes. this is a complete spec, soup to nuts, even the particular sensors used in their design

You can fashion a lung ventilator out of an aquarium aerator

It is also gentle enough to not make you choke on all that overpressure

Also silent

meaning it is a simple matter to implement their design in Marlin 2.0

That's a big plus when you have fever

The only issue with lung ventilators is the software to make them go on and off at a breathing intervals

that way ANYONE with a 3d printer can just use the basic hardware from their printer after printing the parts

That may be an issue

hello

I am talking about EXACTLY THAT

I have a 3D printer, but I am out of filament

I have one roll of PLA left

i have a detailed spect of a real world ventilator

i..e how the software functions

everything required to implement in Marlin 2.0

I have researched ventilators for a different project. I know what they are

I wanted to make a DIY ventilated mask for woodworking

then ANY 3d printer using Marlin 2.0 can repurpose their control board for the ventillator

Faceshield with a cloth fitting for the face and a ventilator that pressurises the mask

provided they can find suitable sensors

which was next on my list

I got to the scheme, but then I found a faceshield at an affordable price that was ready-made

they built an industry portable ventilator into a suitcase using custom PCB

but given they included all the specs and schmetics

Arduino, Pi, chip-24 anything can be used as brains nowadays

dead simple to simply redesign for using Arduino or Raspi 3D printer hardware

yeah, especially if the pdf i have is reimplemented in marlin

it would in essence turn the electronics of your 3d printer into the electronics of the ventilator (after printing the nessecary parts)

AT tiny 45/85 chip can be programmed with Arduino/Pi/PC and then used for youtr project

yup

Much more spreadable solution

that's why i am looking at a Marlin implementation

Arduino board is a bit of an overkill for an implementation

You want a lover level electronics there

that firmware already has all the common libraries for various different pieces of interface hardware

AT tiny costs up to 2.5$ for a piece

only thing need is a ventillator rather than 3d printer application
