How durable is it
@robaki-dev6 ай бұрын
Crashes are inevitable when you push the speed, and yep, parts will break. But, if the car is built correctly, with 3D printed parts that match the design tolerances, using the right settings and materials, it can absolutely handle jumps. It's all about finding the right balance between being strong and not too heavy, so it's tough where it needs to be without breaking the bank on metal drivetrain parts. Every build is unique. Some folks get better results than others. There's always room for improvement, and most of us keep tweaking our builds to make them as good as they can be. It's a process of iteration, finding what works best for your specific needs and driving style.

How about 3Dgears, are they though?
@robaki-dev7 ай бұрын
Yeah, printed pinion and spur gears definitely do the job. The real challenge lies in getting the printer dialed in just right; paying close attention to your slicer settings, maybe having to reprint a few times, and tweaking things until you get the gear mesh perfect. I went with PA12 for these gears since it's supposed to be really good for this use, but I've seen people get great results with PLA+ too.

Hi I'm planning to 3D print an rc car soon. I'm worried about the 3D printed gears, like does it shatter when it fails? Like flying shrapnels hitting your eye.
@robaki-dev7 ай бұрын
I usually avoid looking closely at it while it's running and always keep the body on when driving. It's true that the gears can fail, but they typically don't shatter into sharp pieces like glass or metal. The failure often results in the part deforming or delaminating, rather than producing dangerous shrapnel. For added safety, designing a 3D printed protective cover for the gears is a good precaution. There's one available for Robak. It's great to hear you're planning to 3D print an RC car. It's a lot of fun!

Hi, I was looking at trying to design an RC car aswell although I'm very new to this. Did you buy the parts and measure them before designing around them or did you just work off of online datasheets. For example, I was looking at the HSP drive shaft and I could not find the radii for where it connects to the wheel at 2:30 in the vid, the Aliexpress page for them likewise has no information on it except stating it was suitable for 1/10 size RC cars, I'm not sure if there is a standard size. Would appreciate your help and love your video.

Ideally, the motor mount should be made of the most rigid material possible (metal). This will ensure a constant gap between the spur and the pinion and thereby extend the life (mileage) of the pinion.@@robaki-dev
@robaki-dev8 ай бұрын
@@Евгений-и1т8ь Totally agree, if only my printer could print metal or diamond! At the time, PA12+GF was the most rigid material I had available, capable of handling temperatures above 60°C without melting. The loose fit on the shaft and spur gear cause much more wobble. Guess I should fix that first, but the setup is still good enough to provide many hours of enjoyable driving.

@robaki-dev9 ай бұрын
Hey, thanks! They're made with PA12 nylon. Just read up on this - nylon and acetal are both awesome for gears. Nylon's easier for printing and acetal for machining. Printing helical gears is no sweat, just like spur gears, but machining them is a whole different level. They're holding up pretty well so far, too! Plus, I kinda like the sound of plastic gears more than metal, haha. Cheers! 😀
@carlbModels9 ай бұрын
@@robaki-dev you are so right about the sound, steel is noisy and sometimes rougher. Oddly plastic spur and steel or brass pinion is longer lasting as the plastic absorbs small particles rather than getting worn by them. I saw a spur eat dirt, then sort of reformed itself back to proper shape. Steel sometimes gets damaged and keeps harming itself. Keep on inventing stuff, it's great to see someone actually doing stuff for themselves rather than just ordering it online!! 👍🍺🇬🇧🖖

Indeed, but the other gears in the drivetrain are just cast steel, not top-notch. If I had high-quality machined steel gears, then sure, these PA12 nylon printed gears might be the weak link. Right now, though, they're performing quite well. I'm happy with their performance, and the beauty is, if they ever break, I can easily reprint them 😅

Kits are available from @rcprinter, who prepares them based on the original BOM for various 3D printed RC vehicles. Printed parts are not available for purchase, as owning a 3D printer is highly recommended. The main advantage of this project is the ability to reprint parts at home, so you don't need to buy new ones when they break. I gave one of the cars to a young relative who doesn't have a 3D printer. No worries though, I've got them covered with a lifetime of help with the parts they need. 😄 I recently experimented with a BeagleBoneBlue SBC with Ardupilot and GPS installed and the waypoint navigation worked wonderfully. However, I've temporarily removed it due to the snowy conditions here, as I'm concerned about the electronics 😀. On the Discord channel, I've noticed some attempts at integrating FPV cameras, which is quite interesting. Additionally, there's a reduction gearbox modification available on Printables that I'm eager to test soon to enhance climbing capabilities. I'm really fond of the Robak community and its innovative spirit. ☺️
