3D Printing an RC Car for the First Time
ฝัง
- เผยแพร่เมื่อ 6 พ.ค. 2024
- I enjoyed building and driving this fully 3D-printed RC car in the last couple of months. Even the gears are fully printed in PLA, and they work smoothly (if I keep the power on a decent level). I found this fantastic project called Tarmo on Reddit. This is currently version four and the engineer is working on the fifth one. I was immediately impressed by the community around it. They have a ton of hacks and many people who are continuously helping each other.
The car itself has a crazy torque. I had to limit the power to 25% to stop breaking the gears, and it still pushes like a horse. I made a couple of jumps, only breaking a few pieces. I'm glad it takes just a couple of hours to be on the streets again.

I hope you enjoy the video!
I'd really appreciate it if you consider subscribing to my channel :)
I subbed! More sick builds to come, I hope.
3d printed monster truck
Subbed! Am I right by saying you used prusament PLA Galaxy Black? Also, if you have parts that break easily, a good CoPA such as from the likes of Polymaker will make really durable parts. I like Polymaker's CoPAs because they are designed to be a lot more easy to print than others, although it is expensive.
@@lio1234234 That's correct! It's Prusament PLA Galaxy Black! Never tried CoPA before but I keep it as an option. I'm tempted to try the new Prusament PC Blend Carbon Fiber as well.
@@LeandroLinares true that one does sound good, I imagine it's very rigid, not sure of its durability though. Also, nylon is a great one for gears due to its naturally lubricating properties 👍
i stumbled upon this video.. i really love the concept behind 3D printing rc parts.. it has inspired me to replace some parts on my rc truck with 3d printed parts.. love the video.
That is impressive; I look forward to the continuing refinement of 3D printing.
omg, using threaded rods througg the length of the body is absolutely genius, applying pre-stressed construction to small scale projects
Leandro, realmente TE FELICITO! Que lindo ver que has crecido en todo sentido y llegado tan lejos. Te mando un saludo enorme. Aunque no hablamos mucho, alguna vez fuimos vecinos en la vieja Villa España.... Abrazo!!
Super satisfying to watch! I'm impressed by how easily all parts fit together. Great video and design! Have fun😀
Thank you so much! Yes, for my surprise everything went smoothly
@@LeandroLinares On my side I've to sand every parts before assembling them; the screws and bearing are not fitting well.
Did you print parts @100% scale ?
I printed everything at 100% scale, yes. The screws were ok-ish during the assembly. Now all of them are not fitting well. I wish I shrank the holes or something beforehand.
@@LeandroLinares thanks for your feedback. BTW your video is awesome ! Continue !
Loved the break down and the creativity. Enjoyed it very much.
AWESOME video, of a cool project! The rate that I manage to break my RC cars, I'm anxious to try 3D printing one of these cars. This way I can simply print a replacement part when they break!
Amazing build. Love it
We have a lot of similarities in our printed RC designs. We even have the same dumborc receiver 😆. Good work man nice build
So cool! I plan to do something like this, because I’m tired of ordering parts after breaking them on my old rc car, and if I do this I’ll already have parts!
One of the best build videos I've ever seen! Well done!
Super cool!
Hopefully I can get around to posting a video of my (mostly) 3D printed RC car soon.
I had such a blast designing it and you really get that sense of satisfaction when it just shreds!
I found that printing select parts in TPU can actually prevent breaks from small hits on curbs and whatnot.
Can't wait to see the video! You made me realize I never mentioned in the video that the white parts are actually printed in TPU (Ninjatek Cheetah). The one on the front below the differential gearbox absorbs any hit to the front transmission.
I made the video if you want to check it out.
@@dadsfriendlyrobotcompany saw it and I can't believe the wheelies 🆒
I like the little editing trick you did with reversing the servo + servo mount mating xD
Looks like a great design. I'm definitely thinking about building one. Thanks for sharing
It's so much fun. Not only driving it but also fixing it after breaking something
@@LeandroLinares I found the model files on Thingiverse. Thanks for sharing them with us
Impressed! So Clean!
That was pretty cool. I love the simplicity of the whole build, but great ingenuity on how they were to fasten together. This video has inspired me to try and create my own car. Lol! wish me luck!
If you make your upper suspension arms adjustable, like the rods for your steering, you can adjust your camber and make the car drive much better
beautiful work.
Wow, so clean looking!
GJ! Thanks for the beatifull video!
I just ran across this... Its so cool to randomly see my design out there in the wild! Awesome build and thanks for sharing!
Thank you so much for this amazing project! 🙏
That is awesome , i love the build!
Mind-blowing! Looks like so much fun! Also, your videos are amazing :)
Thank you so much :) :)
So amazing job!
Really REALLY cool! Gonna try to make one here in Brazil.
I would love so much seeing a full and complete tuto how to an RC car from design to final, this can be so dope
YES! In this case it's not my design, but my print. I've been following the designer while he creates the next version of this rc car instagram.com/engineeringns/
Insanely precise prints.
Hey, thanks! I'm always amazed by the quality of prusa printers
Super cool!
Wow It was stunning! I will try to make it based on your instructions! It seems it wil take a week at least...
i love your channel thanks for making this video because i love rc cars
good vid. i just came up on it and have been working on the 3. Would of did the 4 but didnt find it in time lol. will try it. Thx for the vid
Hey! Nice to hear you have the 3. I almost built that one and then the 4 came out so I started gathering the pieces and building it. Now waiting for the 5 that hopefully will come out soon :D
Great Project!!!
Nicely made car and video😀 small channel that needs more recognition. Great work !!!!!!
Hey, much appreciated!
That's REALLY cool!
This is awesome!
You buddy, are a top-notch tinkerer... Very, very nice work 😁🍻👍
Really high-quality videos! You def deserve some more subscribers. Would love to see you tackle a drone!
Thanks a lot!! A drone is on the list of projects, for sure :D
Cool idea hope it holds up
This is relaxing to watch
I am always amazed by these
I hope you can build one soon!
Hi Leandro, this is cool. We were solving problem with PLA melting in our project. Solutiotion is to use ASA or CPE for the parts with friction. And also use brushless motors. They dont heat as brushed.
I was thinking to try PETG for those parts and if it wasn't enough maybe some PC blend (carbon fiber). I hope that's more than enough haha. About the motor: I'm using a brushless motor and I agree it doesn't heat up as much as a brushed one.
Epic video
Respect!
Awesome Build !!! 😎👍🏻👍🏻👍🏻
That's dope!
Fantastic video really enjoyable too watch
Thank you so much. Glad you enjoyed it 🙌
One thing about steering: in center position, servo arm should be perpendicular to link that goes to steering.
Also, I can recommend using PLA+ on arms etc, it'd less brittle than the standard one. And PETG for gears
Every rc build I have done, I have used pla+. It is indeed much less brittle and works well for this type of project. Sometimes it even surprises me on it's strength
But petg is more heat resistant
@@davper8619 that's not needed for majority of parts apart for some around the motor - and PETG might be too soft there. PLA is much easier to print with uniform strength - lthough it's more brittle overall. PETG can be also printed with good layer adhesion, but it takes more effort to nail it.
@@Papinak2 well that good to hear. So I got
His manual and the approx bill for parts besides 3D printing was around 600$ euros, am I looking at it wrong or is that normal for rc cars
@@davper8619 its to much. You can buy good rc car for 300$
the way the music is in time when he cuts the m3 rod👍👍👍
Woow, incredible
I'm building my own rc car from scratch for a school project. With full suspension aswell, any tips?
Hey, nice to hear! The most tricky part for me were the screws and how they fit into the printed parts. It mostly depends on each printer, so pay attention on the size of the holes and change their size if you need to.
For things like the motor mount use a nut on one side not just threading into the plastic
Also don't use 3d printing when it's not necessary for things like the diffs as they could be much weaker then metal ones
Remember to use bearings as well
@@joshuaprescott2930 This is what I've made so far : th-cam.com/channels/5oHQos7H0swedore93KJCA.html
@@wisty0819 looks awesome
The only thing I'd add is some none 3d printed wheels with proper tyres or add tyres to 3d printed ones
And use some oil filled shocks for a better dampening effect
@@wisty0819 I should post the one I've made but it uses a lot of non 3d printed parts
Great work mate
Thanks a lot 🙏
im impressed
Woooooooow!!!! So cool!
Awesome
Thanks!
I'll build my one!
Good job
very nice and cool
you are really very good!
Un proyecto excelente
Very impressive.....
It’s a thing of beauty
9:30 A note on those bullet connectors: Without any soldering, you can place the wire in the connector and hold it in place using some helping hands. Then you can heat up the connector with your iron and feed solder into the connector using that hole in the side which is its intended use. This way the flux in the solder will clean everything and produce a nice solder joint. Cheers!
Oh, and then at 9:50 with the heat shrink, you can have heat shrink cover the whole female connector so there's no exposed conductor to short with the other connectors when everything is plugged in.
Ahhhh, that makes WAY more sense. Thank you so much.
Also, plenty of thick gear grease should have been addded to all the gearsboxes, espcially the main reductor gearbox.
Is there a reason why you would not simply crimp them? I crimp every connection similar to those and never had any problems.
@@sebastianbottger1044 They are not designed to be crimped.
Crimp connectors are terrible, they have high resistance and over time get worse until you have glitching etc
Super well made video!
the prints do be looking hella clean. cool build
Props to Prusa printers. I can't believe the quality they have just out of the box.
6:05 this excites me....... what a beautiful stuff
Absolutely underrated
Muy profesional el trabajo, una maravilla .
Very nice Leo yes that's very time consuming I was just buy one new 😆 great job on making your own RC car that's very creative. Great channel. Just subscribe 👊
Well this was a pleasant surprise ! Nicely done and thank you for including everything. Now if i only had some time. ...
Thank you so much! Yeah, it took me most of my weekends during a few months :D
@@LeandroLinares You are very weclomed.
I did sub, gladly !
awesome!
woah nice project :D
2:46 brilliant idea for pinion!
nice job!!
wow did not think you have so little subscribers, when your videos are super high quality
+1 subscriber
Very nice bro..you have my support after looking at this
🤜🤛
Nice build and good work. I am sure it must have taken some time to design and build. 👍👍
Not my design but my print. It took months to print and get all the parts. I can imagine designing it, and iterating it can take some time, yeah
Good job. Looks really impressive. :)
Thanks! It means a lot
Cool video and this was one of the better ones as it's a quick overview with the backing documents if you want them. I am looking at doing something around 1/10 or smaller scale so this gave me some good tips and confirmed ideas I already had. I did notice the infill for the parts is only 10%? I had to admit I was expecting a high %age or sold fill for any load bearing parts? Are the wall thickness for these quite thick?
Amazing!!!!
Thank you so much! :)
0:39 Por um momento achei que fosse fazer um churrasco! Hahaha Excelente vídeo, edição incrível!

This is so cool. I shared it a few times with friends and family. I love the aspect of 3d printed cars that you can just re-print whatever breaks. awesome!
Quick question: how long does the battery last on this set up?
Thanks for the nice words! I realized I've never used an entire battery charge because I always tried to use the car to the limit and break it haha. I think it's like you said, it's awesome that you can just re-print it. So, I guess I've been trying to test its limits. I don't know how long the battery last ¯\_(ツ)_/¯
Amazing
Thanks! 🙏
Welcome
very nice
I love your camera
You production is very nice. It took alot of time shooting all this stuff. Car is also cool :)
Yeah, in fact it took me so long that you can see after the first half of the video I started learning and experimenting more about lighting in photography :D
very cool project 👍👍 if I can give you a few tips: use threaded inserts, so you are much quicker to assembly. I attached the engine directly to the tire, which makes many mechanical parts unnecessary.
Yeah, that would definitely improve the assembly. With all the vibrations and hits, now a bunch of screws are losen ¯\_(ツ)_/¯
Nice work :)
sooo cleaaan man its satisfying I dont know why you just have 11k subribers
lubricate the gears with a liquid lubricant that doesn't penetrate and that should allow for higher speeds. I tried something similar and that worked pretty well.
Thanks
I love 3D printed stuff, but it's always super clear that it lacks the strength of molded parts. Would be amazing to find some way to have the best of both worlds.
The Prusa just spits out gorgeous surfaces, can't deny
Right? I'm always amazed by the quality, and it's printing relatively fat layers in there (0.20)
@@LeandroLinaresNot bad! I've actually been using 4 Ultimaker 3s commercially for quite a while. And now that ne new Prusa XL is about to debut, I preordered it and I'm seriously thinking about swapping all my UM3s for Prusas as soon as the XL proves itself (my first printer also was a Prusa Mk3). Ultimaker has quite a reputaion for high quality but the 780€ Mk3 still got me nicer results than my UM3s with excessively tested print profiles... The one big mistake that Ultimaker did in my opinion is to not use direct extrusion.
hi, is the car you made in this video still working fine ?
Just wondering if the motor or anything else broke at some point.
so so Kull
I cannot believe the drivetrain didn't explode when you drove it! Amazing print!
Oh, it exploded when I jumped and when I hit the wall indoors. And it's fun to rebuild it as much as driving it!
1 minute in: ok, you know what you're doing! (Unlike too many other 3d printing vids I see).
I've been wanting to print something like this for a while... I'm too lazy and impatient 🤷♂. it took me a week straight for a 70mm delta wing I printed.
I RESPECT IT!
Hahaha, yeah. I tried to print everything while waiting for all the electronics to arrive so I had plenty of time. I don't see myself waiting to print all the pieces now :D
It's a genius to do so far! I want a 3D printer.
Save $150. Wait for an ender 3 to be on sale for $100 (be patient), use $50 for some starting pla and such. Hardest part is finding out how to make the $150 lol. Just depends on your age
@@dollarbutt Be patient and wait!
Nice video
Can you send the solidworks designs of the parts please??
