3D Printing an RC Car for the First Time
Тәжірибелік нұсқаулар және стиль
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 4 and there is also a version 5 (rear transmission only). 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 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. It takes only a couple of hours to be on the streets again.

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.

@@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.
Super satisfying to watch! I'm impressed by how easily all parts fit together. Great video and design! Have fun😀

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?
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.
@LeandroLinares

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.
Nice build and good work. I am sure it must have taken some time to design and build. 👍👍

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

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.
Bro u are so underrated...😭😭😭😭
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.
