3D Printed Air Compressor

showing off , assembling my 3D printed air pump , and a quick peek of possible future projects .
this little pump works pretty good , and I plan on some updates to the design shortly .

you could make the cylinder separate from a top and botton cap , or even use a pipe for the cylinder

[@turboprint3d]

This would definately improve things , however the original idea was to make this a project others could replicate. So the tubes not the best for that , the separate caps would likely end up with a better print for the cylinder . Find some long bolts and tie the head to the frame , I might have to do that . Otherwise it does do the intended job which is to replace an aquarium air pump . I made a diaphragm pump as well which makes a little more pressure but it turns out in practice the piston pump is pretty reliable in comparison . I need better diaphragm material . Projects like this I'm doing my best to work within the limitations of the average 3d printing enthusiast , so simplicity was my goal over end performance . Something more end performance oriented would be my supercharger projects .

Thanks for sharing! I just finished making a centrifugal compressor. It moves a lot of air but doesn't produce much pressure. I need more pressure to run an air blast on a CNC 3018 router. I was just about to start designing a piston-style compressor when I came across this. I think I'll give your design a try before I spend the time re-designing the wheel.

you welcome , if you want high volumes of pressurized air under 3 psi take a look at this : czcams.com/video/SJbkrCtAIHg/video.html

Well done man, also thanks for sharing the design

Stainless steel straws is a great idea

Excellent video. Thanks for sharing. Perhaps the starting up can be made easier by coating the cylinder with some type of lubricant. Vaseline or graphite grease should work.
Keep up the good work

[@turboprint3d]

Thanks , and that lag on startup is the valve sticking to the inlet for some reason causing a vacuum for the first few cycles till it starts up . This is the only one that does this and it's likely because I was using it to pump smoke from a laser engraver as a test and everything has a layer of tar like substance on it .

Cool!

awesome keep it up!

thanks

The piston needs a counterweight

[@turboprint3d]

The weighted crank gear is in the files , the unit shown was mostly the first build . Improves the bounce noticeably

[@tejonBiker]

Looks good, what about lubrication?, Is posible to use some type of oil with 3d printing?

[@turboprint3d]

Ya you could , the petg I'm using is good for most oils , so would abs and nylons , bot sure about pla . A little light grease on the rod and crank bearings , and I have tried graphite on the cylinder and I was going to try dipping a piston in hot wax , peeling it off which should leave wax in the pours. The biggest thing is getting the fit correct between printer settings and fitting . So far I use the biggest wear point has been the bottom connecting rod fit , as while running now it has a decent amount of rod knock , but it's a cheap replacement.

Do you know the max psi such a system could reach?

[@turboprint3d]

With the current setup (380 motor ment for 24v on 5v ) I was seeing 1-2. With higher rpm higher pressure could be achieved . My use case was to replace a typical aquarium pump , witch I'd dose rather well . In fact the flow rates seam to be much higher than. The typical aquarium pump . The diaphragm pump in a newer video is slightly higher pressure but doesn't last as long. I would like to use a oring piston and an sturdier rod to increase pressure In the future . Other things could be done but at some point the bottom end will fail rather quickly at higher pressure . I have not tested to the limit tho . If I were to make a compressor that works over 20 psi I would start from scratch .

Video starting like that i am surprise why it has not been banned 😂, my friend you created a good consumers product 😅 you just need to know who xonsumers are 😂
