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)
Thank you! I was struggling with how having two equally sized stages would compress more, since it is still the same volume of air just being re-compressed.
I was about to type this, the second cylinder should have a volume smaller than the first, and the factor between the two should be the compression ratio of the first cylinder
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.
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 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
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.
I'll definitely need to look into graphite powder! I've heard it works wonders. I forgot to mention it but after I assembled it I did put some grease on the crank shaft and it certainly helped
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.
I forgot to mention but I did add some grease to the connecting rods and the crank, otherwise I am certain under that sort of force they would have melted apart lol. I used high grit sandpaper to sand the parts down as smooth as I could before assembling as well
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.
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
There is no way the second cylinder would add any substantial performance, you probably had a leak and fixed it during reassembly of the 2 cylinder assemblage. When you compress the air in the first cylinder, as soon as you exhaust it into the second, it not just has enough room to expand in the blue line, it also decompresses again 1:1 in the expanded piston of piston nr 2 because the total volume of the first cylinder is the same as the second one. In other words, since the second cylinder can only draw in as much air in an open piston as the first one exhausts in a closed piston, you are in essence compressing it, decompressing it, then compressing it the same. What you need is a smaller piston as piston nr 2 but with a higher leverage advantage to compress pre-compressed air even more. Due to compressor 2 then being able to move less air in 1 cycle, the air between the compressors will get pressurised, making it so piston 2 starts with already pressurised air, and compresses it some more with its increased leverage. Love to be proven wrong.
If the valves were the issue, it would be interesting to see different materials tried for the ball valves or forced valves used. It would be pretty cool to have a 3d printable air compressor that can actually be used for air tools. Particularly if it was turned by a 3d printed dc motor run off of solar panels, so that the compressed air acts as a solar battery
A suggestion on what you could do with it? Use it for an airbrush, most dont need a lot of compressed air and i wonder if it can be consistent enough and give out enough for that to work!
@@swandonovan I'm sure FDM would struggle quite a bit, but Resin would have a much better fit and finish to help keep friction down. It would likely be more of a prototyping piece than a true workshop compressor though and would almost definitely fail over time.
To make a proper 2 stage compressor the volume of the first piston should be bigger than on the second. Either with a bigger diameter or a bigger stroke.
This is so cool! I didn't realise multiple cylinder compressors are a thing haha! I want a V16 fridge compressor just to flex now. Also would have loved to see a vacuum demo by connecting the bottle to the intake. It's kinda funny/crazy to me that engines, compressors and vacuums are all doing the same job of pushing fluids around for us. Another cracking vid Camden you're on fire! Also very nearly at 20K subs, I commented a few days ago that you'd hit 20K soon but I didn't realise how fast the growth rate is. I commented at 17.5K (ish) and now it's 19.2K! insanity!!
Awesome idea! I think I’m going to give it a try, but I’m going to utilize some TPU for gaskets. I’ve worked as a compressor mechanic in the gas fields here in Texas for about a decade.
Suggestion: make a double head in one cylinder. The bottom head is larger with a smaller head attached to the larger head, as one piece. The discharge from the larger head goes into the smaller head suction & that discharge goes to a second set of cylinders set up as in the first set. Your pressure would be increased.
I think if you want higher pressure you might want actual valves. Also I'd suggest a steel pin and maybe some sort of bearing on the crankshaft with lubrication if you want it to last. Though at some point the cooling becomes the issue. I wonder how well you could seal a compressor like this to make a small ac unit, filling it with a butane lighter recharge. (With a small system you'd want probably something like 3g of butane, which would make it about as safe as an almost empty lighter.)
a fix for your pressure problem is to enlarge the cylinder length or widen it but, you might be able to get away with more pressure if you switch your printing style to resin printing or making a check valve system that uses a heavier spring.
I would consider resin printing to get more precise tolerances and maybe increase maximum PSI output. also maybe redesigning slightly to accommodate more or different cylinders (bore and stroke): hitting 40 psi could prove useful in making a printable car tyre filler (if prolonged runtime is possible!) I enjoy the concept
@@CamdenBowen The post processing is definitely annoying, at lease compared to fdm, however the extra work is worth it when you need the precision. I only use my resin printer about once every other month, and it’s still been worth the time, effort, and money.
The drill is likely to cause a heat related failure - keep the temp low with low rpm. The epoxy also isn’t likely to hold onto PTFE tubing for long - recommend pneumatic fittings for that. Cool design though - I really enjoyed it, especially the BB valves.
Wow, awesome! And what about the vacuum pump? They r pretty expensive, and possibility to have a 3d-printed one in a lab or in a chem-class will be outstanding! 🎉
I could be wrong and am in no way even a novice, but I would think you'd be able to attach a hose to the intake and create a vacuum to some degree that way(?)
If you are looking for a reasonable vacuum pump on the cheap (or free) you may consider salvaging a compressor from a fridge or AC unit. The high pressure side can also be up to several hundred PSI on them too. This thing would pull a modest vacuum but it would be limited by the headspace above the cylinder and the volume of the inlet valve body. It also might overheat if run continuously due to lack of gas flow.
You should use a one way valve between the engine and the tank that way you can prevent leak and store the air in the tank without exploding the engine!
2 suggestions a V8 compound with 4 pairs of 2 stage cylinders, I would suggest to make the second cylinder smaller so you actually get much higher compression or a inline 4 cylinder version, but all 4 connected in series, but decreasing piston diameter by 20% each step for the last 2 stages you may need an alternative to O-rings tho, maybe a combined compressor with 2 O-ring pistons and 2 membrane style pistons or something
Cool. I made completely printed hydraulic gear pump that made about 10bar of pressure. And because of the hydraulic oil it even survived continious test of 12hours.
There is a tip making this way better and it's a simple law of pressure: greater the surface, better the pressure. Make another cylinder have 2 times greater diameter.
I added some grease between the con rods and the crankshaft, usually I wouldn't since it creates more resistive forces because of the greases thickness but since this isn't an engine the grease stopped the crank from exploding lol
I like the shelf outro continuation, definitely something you should do every time. Also this video is really one of the best ones yet. Maybe include more one piece memes
@@CamdenBowen Can't wait to see! My engine finally runs (kinda). I can run it off of my breath, but on the compressor, it takes about 12psi to force the piston down, but anything above 10psi makes the valves leak. I have already made some fixes, and I haven't tested it off of the compressor for some days, so hoping it works tomorrow!
@@CamdenBowen How do you get your poppet valves to seal against high preassure? Mine are leaking like crazy. Even after using much stronger springs, they leak after around 15psi
@@hayden3928 Is this regarding the gas engine or the compressor? Silicone was used to glue the O-rings down to the head, and I made sure the surface of the O-ring that will be contacting the BB was clean so it could seal tightly. Hope this helps!
Air compressor for a 3d printer part cooling. We have used air compressors instead of fans for the Hevort. This 3d printed compressor is about 1/10th of the cost of what there using 👌👍.

@@CamdenBowen perhaps i was thinking to connect a 3D modeled airbrush module at the end of the bottle, this bottle ofcourse can be changed in future with better option.
id love to see you send both the 3d printed designs to a 3d printing metal fab see if 3d printed made of metal is strong enough the v twin design id love to see how durable and strong it would be made of 3d printed metal
My apologies, I forgot to include the files in the description. I may make a short tutorial on how to assemble it, but it's simple enough that following the video closely you may get an idea as to how it comes together!
Very cool Maybe make it in to a real air compressor with a air tank from a paint bal gun and a small motor with a case around it to make it look like an industry motor
Maybe add another 3 stages and make it into a radial air compressor? Also I wonder, how much air pressure can a 3D print stand. I've seen a video of 3D printed air tanks, but they leaked like sieves under any pressure without being sealed with epoxy or ABS/acetone slurry.
Not a bad idea, but too many cylinders on one 3d printed crank will be catastrophic, even just the two was pushing my luck a little. Maybe one day I will see just how much pressure this can really do with a high scale gauge and assess any failure points!
@@CamdenBowen, I would suggest printing the crank assembly as a set of disks. First one has a thicker shaft with bigger bearing between it asnd front cover of crank case, with metal bolt in the middle to increase the strength. It also has a hole for another bearing. Back disk is exact copy of this. Then there are two more disks that form the eccentric part of the crankshaft, to which connecting rods are connected. These also have a bigger hole in the middle. The last part is a cylindrical separator piece. The diameter at the ends is the same as diameter of the holes, but the middle part is a bit bigger. It also has a hole for a bolt that connects it to the eccentric bearings. You print all the parts flat, and bolts would reinforce them against layer separation. Increase the number of perimeters/walls and use 25-50% cubic infill, and it should be tough enough. Stefan from CNC Kitchen says so. ;) I'd actually do it myself, but my budget for hardware parts and filaments is very limited, and the parts themselves are a bit expensive in my country...
Recently glass clear PETG print profile on Printables has been making the rounds, and CNC Kitchen covered and dissected it. It is obvious that those prints are about as airtight as can be, so that might be a valuable approach. It's basically a continuous monotonic fill so it evicts the air from the print during printing and fills it with plastic.
I was looking for a small pneumatic vain pump to compress air and push them through a filter that is attached to a helmet. I have a beard so a gas mask doesn’t make a great deal. Instead of shaving I wanted a positive pressure helmet JUST in case we have another pandemic. Thank you for the leg work.

This could be used to launch a series of bottle rockets. If a manifold was designed with pressure gages that would release at the appropriate pressure and then seal and move to the next rocket
Make it so u can put oil in the crank case and then make the compressor water cooled so u can get more rotation and make it 4 cylinder I have never seen one like that that has four cylinders I don’t know if it’s going to be better but it’s worth a try
How was your angle for the twin compressor? Because if they compressed at the same time you would have to add an buffer tank in between them because if not the first compressing Stage would have wanted to press the compressed air into an zillinder which is also compressing. If you did it right they are in an 180° offset that the first stage compresses when the second stage is sucking air in. But you probably did it right I guess but I could not see it in the vid.
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)
I would come to realize this after I had made the final design. I'm thinking of doing a redesign to include this detail

For compound compressors to be more effective, you need a lower displacement on the second cylinder.
You should make a sequence of several compressors hooked up to eachother and see how much psi you can get then find a practical use
Add more cylinders to the compounding setup!

It is obvious that those prints are about as airtight as can be, so that might be a valuable approach. It's basically a continuous monotonic fill so it evicts the air from the print during printing and fills it with plastic.
@@CamdenBowen make multiple twins but use something like a timing belt to run them together instead of a a single crank
I was looking for a small pneumatic vain pump to compress air and push them through a filter that is attached to a helmet. I have a beard so a gas mask doesn’t make a great deal. Instead of shaving I wanted a positive pressure helmet JUST in case we have another pandemic. Thank you for the leg work.
I would like to see you turn it into an air conditioner! That would be cool... so to speak!
Awesome stuff! Keep up the good work!
Thank you sm man!
Make it bigger with more cylinders and try a bigger bottle as a tank. Have a great day/night:)
Thank you! I will see how well it fills up a 4L water bottle if I get the chance!
plz chain multiple of these together and see how high a pressure you can get
now a vacuum pump !! well done sir !
Try to run an airbrush with it. That would be a good test for a compressor that size
Can you attach a motor and use it on an airbrush... just to see how it does with providing continuous flow?
Can you spin backwards to make it vacuum? Would it work that way?
Print many of them and hook them up in series to create the most unimaginable pressure possible.
V8!
Probly needs a metal crankshaft, to reduce friction with the main bearings & connecting rod.
I was watching this thinking "Damn, this fella reminds me of the VinWiki guy Ed..."
Sorry to ask, but what size pneumatic tube should I use?
The OD is 6mm and the ID is 4mm I think, it's easy to find online
You should connect this to your air powered engine
Man your editing is getting really good! I like how you tell the story in the voice over. Keep this up and your channel will grow fast! nice haircut btw
Thank you so much man! I'm glad you appreciate the editing style as I've been experimenting alot with different things to see what works!
very nice! 👍 what would you think of a tutorial? I would really like to have a 3d-printed air compressor. so if you are bored, that would be pretty nice. I am actually also surprised, how well it worked. I think you are a pretty underrated channel, because your projects are fantastic. Please keep up the good work.
Thank you so much! I can surely do a more in depth tutorial on how to assemble it along with a list of parts!
@@CamdenBowen @Camden Bowen Yes! that would be great! I already downloaded the files and now I'm taking a closer look to identify what I'll need, but a tutorial with parts and 'how it works for Dummies' would be awsome!
Just foud you channel and I'm loving it! good Work!
This could be used to launch a series of bottle rockets. If a manifold was designed with pressure gages that would release at the appropriate pressure and then seal and move to the next rocket
last week I printed a O-ring with tpu and its still holding up. it can resist at least 6 bar
I would love to see this connected to a wind turbine storing energy in the outdoors
Make it so u can put oil in the crank case and then make the compressor water cooled so u can get more rotation and make it 4 cylinder I have never seen one like that that has four cylinders I don’t know if it’s going to be better but it’s worth a try
what about running it in reverse?
can it be a vacuum pump?
you can try using a harder bottle like a coke bottle. i would love to see a compressor with 4 cylinders :D nice projekt. keep it up
Can you make a vacuum engine out of 3d printing filament
How was your angle for the twin compressor? Because if they compressed at the same time you would have to add an buffer tank in between them because if not the first compressing Stage would have wanted to press the compressed air into an zillinder which is also compressing. If you did it right they are in an 180° offset that the first stage compresses when the second stage is sucking air in. But you probably did it right I guess but I could not see it in the vid.
I did a simple 90 degree angle for the compressor, it seemed to work fine and be space efficient
have you tested to see how well it will pull a vacuum?
Love this! Instantly subscribed
What is the flow rate? Could you make the cylinders smaller and have more stages to achieve ultra high psi?
