3D printed Toyota 22RE engine

Printed on a homemade RepRap Prusa 3D printer.

Completely reverse engineered Toyota 22RE 4 cylinder engine. Can completely print a fully rotating model. Working crank, pistons, and valve train. The valves open and close!!!. It may not be the most exciting engine but its the only one I had in my garage. Great if you want to learn about engines and how the moving parts in them work. All parts are printed except for a few bearings and fasteners.
More than 3 days of total print time.
The block alone was 34 hours. So make sure you have a well calibrated and reliable printer.

Some print times calculated in Cura at .2mm layer height
Engine Block - 40 hours
Head - 23 hours
Valve Cover - 10 hours
Oil pan - 14 hours

See Thingiverse for all the info and part files.

My 17 year old son just has the engine block left to print. This is awesome and it really inspired him. Thanks for taking on this project!

This is awesome. I went to a technical college for automotive maintenance and having not grown up with access to cars to pull apart, it's models like this that made understanding and learning possible for me. With that said, this model was probably much cheaper and did just as well if not better job at demonstrating part movements than anything I had in college. I have yet to mess with 3d printing, but I truly admire it's capabilities and the work and time every creator puts into each print. Thanks for sharing.

I had this motor in my Celica but with a auto trans. I had no complaints about it. It would burn first and chirp 2nd and 3rd. It was the best 500 dollar beater I ever bought in my early 20's

I dont usually comment on videos, unless something exceptional! As an ex mechanic i will understate that This is pretty exceptional!

One of the best 3D printed models i have ever seen.
Very good work !!

Absolutely awesome! I've built a Miata engine in Blender - down to the nuts and bolts. I can appreciate how much extra work it would be to then optimize it for print and to finish each part. Incredible work.

Very cool. The 22RE is a fantastic engine too! Can't beat the old pickups with 22RE (and 4WD if you're in snow areas).

I printed all the parts but putting it together is a pain haha. It woulda been awesome if you did an assembly video - or a complete assembly guide. However, with a lot of troubleshooting, it IS going together. You are awesome for reverse engineering this! I really hope I can get it to run on its own... So far the parts move manually all together. I hope you continue to post more files for different engines! These are fantastic, you are super talented.

I don't like people losing their shit over a 3d printed things that could have easily been done with other technology but this thing is actually pretty cool

[Gunshot]

Wow, that is really incredible. Just being able to model something like this is incredibly educational. Great video :)

[YotaMan]

YESSS! One of my favorite engines, this is AWESOME!!!

I wonder if 3D printing can become the future for remanufacturing old parts.

[bennyturbo]

WOW that's amazing! looks great and I'm a big fan of the 22 RE.

OH. MY. GOD.

Eric, you're a GENIUS!!

Thanks for posting this on thingiverse.  I will definitely have one of theses running on my desk one day.  Great job!

Awesome work. This would be lots of fun for a cad class.

The gear that drives the Cam Gear is called the Crank Gear, it sits on the Crank Shaft underneath the Oil Pump and Timing Chain Cover. The Crank Gear rotates the Cam Gear buy meshing the Timing Chain to the teeth of the gears. I Imagine if you can do all this so far, you wouldn't have a problem making it more detailed. Also a Cap-less Distributor would be neat with a couple Dizzy Gears, one being on the Cam Shaft.

favorite engine, thing is indestructible and so friggin simple.

That's amazing! It is very good quality for a diy 3d printer
