Who says that you can’t make anything useful on a desktop 3D printer? Sure, there are plenty of designs that you can find on 3D printing repository websites which make you question the motive of the designers — but at the same time, there are engineers and designers creating things that make you just stop and say, “WOW!”
One of these latter instances comes in the form of a 3D printed 5-speed transmission for a Toyota 22RE engine, created by a mechanical engineer named Eric Harrell of Santa Cruz, California. Not only does it look legitimate, but it also is completely functional.
You may recall a story that we did back in January about a 3D printed Toyota Engine. It was also designed by Harrell, after he completely reverse engineered a real Toyota 22RE engine. It received such a great reception from both Thingiverse users and the national media, that Harrell decided to take his creation one step further, providing this latest 3D printed transmission to complement the engine.
The two actually can be combined to create the ultimate piece of 3D printed machinery.
“I made the transmission due to the the success of my first upload, the 4 cylinder Toyota engine,” Harrell tells 3DPrint.com. “The overall number of people that were interested was overwhelming. I never thought that many people would be interested in it, yet actually print and build it, due to the shear complexity and print time involved. So far 8 people have made the engine and many more are in the process.”
In all, it will take about 48 hours of print time to print out all of the individual pieces needed to assemble the transmission. Once the pieces have all been printed, they will need to be assembled using the diagrams that Harrell provides. He admits that it’s not an easy task to put the transmission together once the parts have been printed, but welcomes questions from anyone who has difficulty doing so.
“If one was to build either my transmission or engine, they would have a pretty good idea of how to put an actual engine together since these are modeled after real parts,” Harrell tells us. “Which is great, because most people that are interested in 3D printing would never get the opportunity to actually rebuild an engine or transmission.”
While the majority of the transmission is 3D printed, there are some smaller parts which can not be printed on a desktop 3D printer, such as the 3mm rod, (18) 623zz bearings, (20) 3mm washers, and a few other small odds and ends like screws and bolts. At the same time, Harrell doesn’t ensure that all the parts will be ready to go off of the transmission4printer. Depending on the 3D printer used, some of them may need to be scaled up or down in order to fit together properly. Rather than scaling the parts, he also suggests that you could simply file them down where needed.
“The transmission works exactly like most manual transmissions found in any car or truck,” explained Harrell. “However, I can barely explain how it works. It’s fairly hard to grasp unless you assemble one or see an animation of one opened up.”
Regardless of the time required for printing and assembly, this has to be one of the most incredible designs that we have come across yet on Thingiverse. Most incredibly, Harrell tells us that it could absolutely be used in a real vehicle, since it is a scaled down version of the real thing.
What do you think about this incredible 3D printed Toyota transmission? Have you, or will you be 3D printing your own? Discuss in the 3D Printed Toyota Transmission forum thread on 3DPB.com. Check out the video below of the 3D printed transmission in action.
From one Chrysler to another and you are worrying about saving money?
But the gist is that the 3d printer can make metal parts as well.....................
FIAT..........................Fix It Again Tony!..................
Socialism is a hundred grand....................and then some..............
The Visible V8 (by Revell models) is still available.
50 bucks or so (a bit higher than I paid back in the 60s I’d say for certain.)
Still has a carburetor too.
The Visible rotary (Minicraft) is available for $60 with a transmission.
Mass production may be infeasible, but theoretically, I see potential here for print-on-demand production of rare and unavailable parts for vintage vehicles that are no longer in production.
That’s already a market with the Scan-print gig.
Takes some effort to scan complex parts but eventually you can get there.
Harrell essentially did just that. Guarantee you he does not have the geometry for those gears except as a scanned surface.
I think he really means that a working unit made of metal would be feasible and economical to manufacture. It’s coming..................
...
Jet engine parts are being made with a different kind of 3d printing. Spacex is making parts including small rocket motors with printing also.
Great! 3D printing enthusiasts should use that engine and transmission in their vehicles.
Metal Gears that don’t need to be finished?
You'll get pretty lonesome and hungry waiting on one of those engine/trans to come in for a swap. The word "bombproof" was invented to describe both.
While you were building that engine, I was building the Visible Woman kit.
It came very handy a few years later when I started dating.
Very very cool, but I don’t think they will quite come in with the tolerances required of mesh gears that will be needed any time soon.
Now 3D printing the diecast molds to make them out of metal and post grinding the parts, that is another story...
There may be 3D printers coming along that can make “metal” parts but I doubt the metal will be of high enough quality to function as gears, cylinders, pistons, even engine blocks any time soon.
You were way ahead of me...
Mine has 250k on it. He’s still investigating.
Not if its for your own use i guess
Yes there’s no prohibition on building substitute replacement parts for OEM parts unless the part incorporates patented technology.
Manufacturers of commercial aircraft went down this road 2 decades ago, prototyping mockup components; and, working out issues before tooling up for actual parts. Now actual parts are fabricated to shed +10% weight over results obtainable with traditional machining/ fabrication techniques.
NASA needed a fuel injection assembly for an F-1 returned from museum storage. Traditional supply operations forecast delivery of +1 year. Printing a working unit was achieved in a abbreviated time frame.
