- I was disappointed by the durability of my new RC Car. I solved this issue by 3D Printing some flexible TPU parts for it and did some durability testing - I wasn't able to break them! Car is a Wltoys 124019.

Next one I'm making is about a super durable 3d printed rear wing for my Arrma Kraton :)
Dude teach me!
I want to hire you for a experimental rc vehicle procedure.subscribed man.we want more.
You just revolutionized the rc industry.
The secondary benefit of this is this is where the energy is being absorbed now into the flexible TPU so hopefully any of the weaker plastic parts may stay intact with this mod
yes, that's also true :)
Looks like a good compound for basher car’s! Well done! it’s probably too pliable for competition though, reducing weight and adding rigidity is critical
True :)
I’ve printed same 3 months ago with TPU and it was really very very strongly!
Very cool 3d print! Thanx for sharing the link with the rest of us! Thumbs up! New sub here! Cheers!😎
No problem, thanks for the thumbs up and sub! :)
I was hoping for the actual 3D printing process video in action 🤔
You mean like a timelapse of the printer printing the part?
If so, I'll be including that in my next 3d printed parts video :)
@@ValRC1 yes 🙂
And we need more information about plastic, slicing and printing
@@Artemon-yl5ze Thanks for the suggestion, I'm working on an upgraded version of these parts right now and I'm gonna include that in the video!!
Nice video, I like all the testing (:
Thanks, appreciate the feedback :)
I'd print the body of the part with more density and the ends with a bit less since theyre more prone to breaking and still keep the rigidity of harder plastics for predictability
Yup, I've actually even got a video in the works showing how I made them stiffer in the middle and even more durable at the ends!
@@ValRC1 nicee
I'd thought about TPU for arms before, my only concern is that the flex will put too much strain on the camber and steering links, as well as the driveshaft. Awesome to see it worked out though!
Works great! I just don't recommend it for racing or speedrunning as it does make control a slight bit more imprecise because of the flex
Awesome
grüezi ! das is echt hammer ! muss ich gleich mal ausprobiere !
Unbedingt, viel Spaß dabei! :)
Thank you very much for this video, you got me interested and will buy a 3d printer now, I have a lot of rc cars so this should be interesting , in general where do u get the models of that you want to print , is there a 3d scanner to scan the original item and then print or you find it online?
I either download them off a website like thingiverse.com or 3d model them myself in CAD programs like Fusion 360.
3d scanners exist but are expensive and the cheaper ones don't work very accurately
Also: no problem, glad you enjoyed! Consider subscribing if you want to see more like it
Interesting, I wanna try 3D printing too and fascinated by it. looks like the part behaves like hard rubber and has nice flex. I wonder if you can use carbon fiber as material to 3D print, that would be awesome. cool vid, 👍
Thanks for watching!
You should definitely give 3d printing a try, it's pretty cool! Yeah I'm thinking about trying some carbon fiber infused nylon filament, only issue with that is it's pretty expensive..
@@ValRC1 Expensive and it absorbs tons of humidity out of the air and needs to be kept very dry. Nothing worse than spending $100 on a roll of filament only to have it print poorly due to moisture!
@@GeddyRC true, the moisture thing is an issue with nylon as well. Especially since the basement I print in frequently has humidity levels over 70%
Great fix, man! I guess it was brittle because of the low temperature. But the printed piece should last way longer!
Thanks man! I'm actually working on an improved version on it rn :)
The plastic on this one is still brittle, even now in summer - my guess is still that they messed up the plastic composition
its also brittle so it will break so they can sell more parts. They could make more durable plastic but theyd also make less money.
@@mech0p it's so weird because with wltoys it's hit or miss. I've had 2 that are pretty durable and then this one that just shatters when you look at it the wrong way. My guess is bad quality control
Wow very flexible, looks like rubber almost
Yeah they are! The material is TPU (Thermoplastic Polyurethane) and many people also use it for fpv drones, usually survives high speed impacts into hard objects with them!
Oh and thanks for watching! Appreciate the comment too :)
Interesting.!!!
I love this! What 3D printer did you use? I’m looking to do this myself and wondering what printer I could get to make something similar.
I used my Prusa I3 MK2.5S, but you could use any 3d printer that's able to print out 95A TPU well :)
@@ValRC1 lol, I ran into troubles with a printer I won’t mention here, but now happily printing away. Thank you again, this is such a good idea
@@peterwatkins671 nice, glad you got it running by now
Had the same car it was a blast actually sold it for more than I paid for it new
Damn, how did you manage to do that?
Either hub or arm pins will tear it or come loose upon impact. You might have to beef up those areas
Haven't had that issue yet. If it does happen I will, thanks!
Not gonna have any issues, the way you dive, anyway lol. Send it with these arms, then talk.@@ValRC1
What would be really interesting is to print the core from PLA and then outer side from TPU. Might as well embed some carbon fiber rod as a core :)
Hmm, to be honest I think the PLA code would just break 😂
Would make sense to beef the TPU arms up a bit more so they're a little bit stiffer though, thanks for the idea
Good stuff. I would have thought tpu would be too flexible. Maybe if it was hot outside it would flex too much. In cold weather I bet it's perfect though.
Actually, in summer with the stock brushed system it was fine. Once I upgraded to brushless though (100kph on 3s..) I did notice it a little bit. I now made new arms, still out of TPU just a little beefier, which made them stiff enough to be used with brushless as well :) video is coming somewhat soon
@@ValRC1I printed one with pla at 80% infill and so far it hasn't broken. I crashed it hard enough that I broke the diff case instead of the 3d printed part. I'll have to see how well the 3d printed diff case holds up.
@@joacimlopez9735 oh that's crazy, means the wltoys parts are sometimes weaker than pla!! What a shame really
i like this... strong but flexible..
Yup, works very well
What did material of 3D print you used?
I used Sainsmart 95A TPU material! Thanks for watching :)
@@ValRC1 thank you 🙏
What kind in terms of Shore hardness is your tou, If I could ask. Regards
It's 95A Sainsmart TPU :) thanks for watching!
Thanks@@ValRC1
What filament did you use
I used Sainsmart 95A TPU filament :)
This is very cool i wonder how it would work on a big car like e revo maxx or xmaxx mabby some kraton 6s or 8s just a heavier car
Hmm yeah, it could work, but i think TPU is a little to soft for that. I might try it with some Carbon TPU or Carbon Nylon though! Thanks for watching and for the feedback, appreciate it :)
what filament did you use to print the parts?
I used Sainsmart 95A TPU :) thanks for watching!
more flexible like classic PLA no ?@@ValRC1
@@xavierledieu3406 yes, it's a lot more flexible than pla. Pla is very hard and brittle
Soooooo, what did you use exactly? Most of the 3d printed stuff I've encountered has been brittle and its put me off getting one, I'm just learning tbh excuse my ignorance its probably a stupid question.....
Nah not stupid, I used Sainsmart TPU Filament, flexible super tough stuff, but can be a bit finicky to get printing on some printers, especially those with a Bowden extruder.
There are different non-brittle options that are a bit stiffer as well, like for example Nylon or PP.
The most typical and also most brittle Plastic used for 3d printing today is PLA.
@@ValRC1 cheers bud very helpful.....👍👌😁
@@EZ-D-FIANT np!
Here is another comment to tickle the algorithms biscuits because I liked the video
lol thank you
Hello, I would like to buy the bumper that you made in 3d, it looks good. Is it resistant?
It's been pretty durable for me, just make sure you secure it with all 4 screws and it should last a while. I don't have an official shop or anything yet but if you're comfortable with it I could sell you one privately.
@@ValRC1 I don't mind as long as it's a good price. Sorry for the late reply.
@@andrealves1250 all good, I could sell you one for $5 + shipping. where are you located btw? So i can look up the shipping costs there
I like to ask i know hobbyking sabertooth 1/8 scale parts are no longer available do you make spare parts for customers
Which part(s) did you break? Not all are good to be printed out in TPU filament, but some might work well
It's the front and rear control arms
Interesting. Thanks. How much infill did you use for the arm and the bumper?
The arms are 100% infill, I'm not sure how much infill the bumper has but as you can see it doesn't have and top or bottom layers in the front part..I'll check real quick
so the bumper has 100% infill in the back where it mounts to the car and 15% infill in the front with no top or bottom layers, to absorb and dampen impacts :)
Btw I'm thinking about doing a video with a few 3d printed mods/upgrades for these wltoys cars, do you think you'd be interested in that?
@@ValRC1 Thanks for your answer. 3d printed mods for wltoys are always interesting. 😉
@@jochenweisel8612 No problem, thank you lol
I've made a few parts for my cars with a 3d pen. But I just use PLA. I wish they made a pen that could extrude that material. Might be worth it to make my own.
Damn, didn't think of a 3d pen but I'm guessing 3d printed parts are stronger due to being solid?
@@ValRC1 using a 3d pen the parts are nearly 100% filled. For a swing arm like you did I would ink out the part on paper and just trace it with the pen until I had enough layers to reach thickness. There are a lot of 3d pen sculpting videos on TH-cam that show you how. For me, I can't justify buying a printer if I can't model my own stuff and I don't have the motivation or time to learn blender.
If you want to decrease the amount of flex on that particular part, increase the number of perimeters or a harder shore TPU material.
Thanks for the suggestion! I printed these with 100% Infill, so I guess adding more perimeters wouldn't make a difference? I bet a harder shore TPU would work great though
@@ValRC1 it will make a difference, because you have to understand how the layers are put over each other. You can experiment this by printing a simple rectangular piece with PLA, lets say a 10mm wide by 50mm long, And 3mm thick.
Print the first one with only 2 perimeters and a second one with 5 and try to bend them and feel the difference.
Anyway, if you use the car for bashing it won’t make much of a difference but it’s something useful to know for future projects, sometimes you can also get sufficient strength with this method without using 100% infill and save some plastic.
@@ripmax333 oh okay, well guess I learned something new today! Thanks, will definitely make use of it for future projects 👍
wow amazing man my wltoy is going through a rebuild and I'll definitely be down to use your arms if you sold them hope to see a online shop maybe soon 😄
Yeah we'll see, probably not very soon but maybe sometime, if there is enough interest for them!
Where are you located btw?
@@ValRC1 Singapore!
@@shivasaravanan3032 oh dang, i was thinking I could just send you a pair before doing a shop or anything but I think shipping from Austria to Singapore would be pretty expensive...
@@ValRC1 it's no problems I can cover the cost
What is the shore hardness of this tpu?
I used Sainsmart Brand Shore 95A TPU for these arms! Thanks for watching btw :)
Cool

Amazing !!!👍
I can’t see a link to make these parts…👀 i would like to print it myself cause i have that car aswel and there are some parts already broken. Could you send me the link please. Thanks😎
If you have time…. Maybe a hole car in this material would dramaticly change the world of safety aswell 😂💪💪💪
Oh sorry, I forgot about the link! I added it to the description now so you can print it out as well :)
Maybe if I have time for it at some point I'll 3d print a whole car ;)
Thanks for watching, by the way!
What kind of motor is there?how many kv?
In this video I was using the stock brushed motor
For bashing, this is perfect !
Yep, btw I already uploaded a video on an updated version of these!
damn this is smart, im going to save so much money
Awesome, glad I could help! I actually have a video of an upgraded version of them coming up :)
COULD YOU LINK THE FILAMENT YOU USED?
Sure, it's Sainsmart 95A TPU

Thanks for watching btw!
@@ValRC1 Thank you for making cool RC video.
@@m0neez np, more are coming!
What other parts can you make for other RC cars?
All the parts where it makes sense for them to be flexible :) I can take a part off a car, create a 3d model of it in fusion 360 and print it out!
hey what kind of 3d printer do u have
I have an Original Prusa I3 MK2.5S, but you could do this with any printer that can print TPU material
Hi,
welches TPU von welchem Hersteller hattest du bei dem Arm verwendet?
Sainsmart 95A TPU, habe ich schon viel verwendet und ist echt super 👍
was für solche Sachen auch noch interessant wäre, ist das Carbon-TPU von Extrudr, da es etwas steifer ist, aber vielleicht trotzdem so widerstandsfähig wie normales TPU ist? Müsste man aber ausprobieren
@@ValRC1 Tja, Extrudr ist ja auch aus deiner Heimat. Machen sehr gute Filamente.
Grüße aus Deutschland.
@@lutsifer5847 einer der Standorte ist tatsächlich sogar bei mir um die Ecke im Industriegebiet des Ortes, wusste ich bis vor kurzem gar nicht
@@ValRC1 Ist auch von mir ca. 90 Km weit weg. Also auch quasi um die Ecke.
@@lutsifer5847 nice!
Would you be able to share the file for the bumper?
Not sure how I would do that tbh - the STL of the bumper is solid and then, with some modifiers and infill trickery i made it the way it is in prusaslicer
Specs on your printer settings and filament type
It's an Original Prusa I3 MK2.5S, using the SainSmart TPU preset in Prusaslicer and with speeds reduced to 20mm/s, Material is 95A TPU
Can you make the design for the rear arm pleaseeeee
www.thingiverse.com/thing:5335779 it already exists on thingiverse :)
I wish I could do that for my fix vantage.its chassis keeps braking.But I don't have a 3d printer or the money for one. Also does anyone know the song used for this vid.
Oh, that sucks. Maybe you could trim and fit a metal plate or something to stiffen the chassis up a little?
And which song do you mean? (At what minute in the video, there are multiple)
@@ValRC1 I've had to replace it 4 times
@@ValRC1at 1:08
Nice man, you should start selling them I would buy from you!
Thanks man, yeah I've been thinking about doing my own rc car upgrade onlineshop. Maybe I'll get around to it sometime soon!
Where are you located btw?
imagine that TPU A-arms make an RC drive and turn better due to more 'flex' and maybe dampening in a way giving more grip e.g. more ground time for the tires.
i could absolutely believe this but this theory isn't tested as far as i know?
Maybe this can be true in some cases, but I actually noticed with these super flexible ones that the handling got slightly worse once I switched to brushless power. I made some new and improved arms to fix that, new video is out on my channel already!
hey, can you tell us what's your 3d printer setting?
Sure, I just used the default Sainsmart TPU Profile in Prusaslicer and reduced all the speeds to 15mm/s. Thanks for watching!
@@ValRC1 tyvm for the fast reply!
@@FeraAlfian-vu1wy no problem, glad i could help
What category of TPU did you use?
I used Sainsmart 95A shore hardness black TPU!
@@ValRC1 Thank you so much... very very very interesting test.
@@josemariaferriazorin9930 no problem, feel free to subscribe if you want to see more videos like this one!
This is a sure way to bend your dogbones/CVDs. Since those arms absorb, virtually nothing, all the impact is transferred to those metal parts, and surrounding plastic parts. This much flex, is just too much.
Nah they're fine, the wltoys CVDs are usually very weak anyways but I didn't notice any changes with that once I put these on. I did make a stiffer version in the meantime though
Neet, what car is that I have one that looks similar.
It's a wltoys 124019 - they make a few pretty similar ones
@@ValRC1 ok what I have is a WLtoys A959-A and Im upgradeing it to A959-B which is more powerful. I got the car for free but I have already probably put more in to it than its worth
What material is that
Sainsmart 95A TPU!
Clearly the part you made is going to last longer as it is not as brittle but since it is fexible, it cannot work properly as a suspension arm. Suspension arms need to be stiff to allow the shocks/springs to do the work. In saying that, for just a fun car to play with, why not!
It seems to have worked pretty well and I didn't notice too many suspension or handling differences. That being said, the suspension on this car isn't very good to start with so there's that. I'm currently testing a new version of these arms that are beefier and stiffer, btw!
What RC car is that? It is pretty quick!
It's a wltoys 124019! Thanks for watching :)
How come that part was on thingiverse?
Because someone designed it and uploaded it there
I must have missed it but what filament is that part made of?
It's made of 95A TPU
@@ValRC1 PETG would probaly also work pretty good i guess. atleast allot better than plain pla probaly
@@DiyNuke honestly, Petg isn't as impact resistant as most people say. TPU is waay more durable if it doesn't matter that the part is flexible. A more impact resistant alternative to PETG is PCTG, or if you have a good printer and an enclosure Polycarbonate (probably the most durable stiff material)
Send it to the moon!
I don't have the money to replace half the car lol, maybe in a later vid
Can you find the 3d print thing that holds up the front wheel
Which part exactly are you talking about?
Maybe you could send a link if you don't know what it's called?

Not sure if there's a 3d file for the a959? I'd need that to print them
What type plastic did you use?
95A TPU!
@@ValRC1 thank you,would this be better than nylon for thinner type bumpers for a trx4?
@@bud1lite Nylon would probably optimal since TPU might be a little bit too flexible I'd think
Whats the point if you can't break it
The point is to take the bad stock part that breaks easily and improve it so it can't be broken anymore
You should make a full upgrade set like the aluminium upgrade sets that you can buy for these cars . I wood buy them we have 4 of these cars 2 124016 1 124018 1 124017. I am sub no 20.I live in canada.
That's a great idea but honestly, I think it would make more sense to make the arms out of this flexible plastic and then the c hubs and stuff from Aluminium. The bulkheads (a major weakpoint of these cars IMO) also can't be from a really flexible material like this, as that would make the screws rip out even more easily and maybe even make the gears not mesh correctly under load due to the flexibility
@@ValRC1 That is a good point . The a arms and a bumper like the lc racing one with the foam in it but without the foam would be hot sellers .
Hi what would be the best cheap printer to get for making parts like this thanks. Wont be long and you will be up to 200 subs way to go.
Not sure about the current 3d printer market as I've had this one for like 7 years and am happy with it, but you should look for one that can print TPU Filament well (Filament used in this video is Sainsmart Blue 95A TPU)
@@ValRC1 Thanks looking at a ender 3 pro but not sure
'Thermoplastic Polyurethane'
yes
It that a sweet amazon willpower rc?
Not sure what exactly you meant, but the car in the video is a "Wltoys 124019". Does that answer your question or did you mean something else?
@@ValRC1 no sir, thank you, i confused the wltoys with willpower, thats what i meant. Bang for buck, theyre rippers.
@@dondagy9109 np, yeah they're great for the price, I have a 144001 I converted to brushless and this 124019 that's still on brushed :)

@@dondagy9109 yeah definitely. What happened to mine was that the motor broke, so instead of getting a replacement I just threw in an old brushless combo I had :)

Iirc I downloaded that one from thingiverse
@@ValRC1 how much the part you've printed weight?
I need 😢
Amazingly durable but now to make it rigid so it has no flex but remains unbreakable??? 🤔
The flex is what makes it so durable, but for Version 2 i could fill in all the gaps to make it stiffer and more rigid
@@ValRC1 Yes I completely understand, but flex in suspension other than from the shock is not good. If you are not racing and you are just bashing you came up with a very good way to have fun and not break arms ✌🏼😎👍🏻
@@mikesrcgarage Yeah that's true. I'm only a basher atm, but i think some type of carbon fiber infused nylon filament could work for racing. That's expensive and difficult to store tho. (absorbs moisture easily)
@@ValRC1 Yes that is the key and very expensive. On a very light car the flex is not a real issue and as long as you're having fun that's all that matters. My 1/5 scale breaks arms just by looking at it! Lol! Keep up the good work and the WLtoys you were running looked like it ran great with those arms! ✌️😉
@@mikesrcgarage thanks man, appreciate it :)
Are your 1/5th scale arms very stiff? Or from nylon like typical on 1/8th scales?
If you can make them that tuff why can't the manufacturers or is that too obvious
Probably because it's cheaper this way, making them out of cheap hard, super brittle plastic

I'm glad you like it! Greetings from Austria :)
Love the video but please clean your camera!
Thank you! Unfortunately it's broken and what you see in the vid are glass particles on the lens under the cover which can't be taken off :/
I've raced alot of rc cars, I even went to the nationals. There is no such thing as unbreakable.
True
Pretty sure the new models are aluminum.
I'm pretty sure they're still plastic, but you really don't want aluminum for these specific parts anyways. That would just transfer the impact force further into the car, breaking parts that are harder to replace.
You want these to either break or absorb the impact.
Yep, just like Val said, its almost like a real car with crumple zones
Yet im running upper and lower aluminum arms on my udr😄
