The 3D Printed Air Compressor: Will it Work?

Today, I 3d printed an air compressor. Lets see if it works. Compressors are useful as they can store potential energy as form of compressed air. This pressure can be later released as kinetic energy to run something like a 3d printed air engine for example. The idea is to create a 3d printed air compressor, the design is very similar to that from my 3d printed gas engine. The biggest differences include a piston with more o-rings to hold greater pressure and heads with check valves to work without the need of timing devices.

Interesting
I think most dual cylinder high pressure compressors have different size cylinders to increase compression. The "first" cylinder is bigger and the "second" cylinder is smaller (in volume)
Considering I’ve watched many attempts at building similarly scaled milled and CNC’d superchargers and turbochargers out of metal that barely held 4psi, I’d say this is a major major win.
I coupled a single cylinder 2 stroke RC engine with an electric motor and was surprising good at supplying air, obviously in pulses and a little warm but surprisingly good
Might be a little late to the party but i think it would be interesting to hook it up to an airbrush. Compressors made for airbrushing are often quite expensive so to see how well a 3d printed one could do would be cool
I love "practical" 3D prints like this
really cool video! I thought the bearing less crankshaft had no hope of survival but its cool that it stood up to a drill. I am making air powered engines and I have no luck if it doesn't have a bearing, all of mine melt or explode if they don't have a lubricated bearing but yours held up really well.
Ya know the truly amazing part of this is the pressure holding abilities of a simple water bottle. I inflated one (actually many.. we were playing with bottle rockets on a slow day at work) with the air compressor at the shop and had it up to approx 150 psi if memory serves me right. Bottle rockets really do rocket when you chuck 150 at em. lol
I recently found your videos and love them! I wanted to recommend using some graphite powder on your crank shaft connections or any other parts that rub or spin around each other as a dry lubricant. I have used some on projects in the past and it works wonders.
Awesome work bro. Thanks ❤for the bb valves & copper sleeves for my other projects.
i love how simple it is
You always make really cool things this is awesome
Love this! Instantly subscribed
Awesome stuff! Keep up the good work!
I'd love to see this scaled up. The tolerances in 3D printing aren't great for things like this but as you increase the flow volume the compression losses are a smaller percentage of it overall. If you can use teflon seals and proper bearings for the crank you would be able to run it faster more reliably, plus an air tank with proper fittings would be nice also. Copper tube for the cylinders is a great idea to help with heat which is pretty much going to be the limiting factor on performance for any compressor with plastic parts.
great stuff! I learned a lot, thank you!
This sounds perfect for degassing resin for casting dice
I might have to build one for some of my projects 😂, great video bro!
Great video. Love to see a new face with great ideas and well edited video. You earned a subscriber. Cant wait to see more good videos from you.
That’s honestly so cool. I didn’t think this could be done
