Very useful guide for many. I have successfully printed and reinforced timing belts with stretch as low as purchased ones. 1. Use your single walled printed TPU belt (thinner the better) 2. Apply a thin coat of rubber adhesive layer on the outside of the belt 3. Wrap the outside of the belt with PE (poly ethelyne, fishing line) or kevlar or fiberglass, or even mult-strand metal wire. Wrap in a continuous spiral loop as much as you need, only cutting once after it's fully wrapped. 4. Coat the wrapped belt with another layer of rubber adhesive. These belts are as good as the real ones but the TPU teeth are not as durable if the friction is high. Also you can experiment with stop-impregnate-resume printing technique of embedding the string inside and melting metal wire into the tpu, both of which are much messier and have not had good results. For me the technique I mentioned above works great for prototyping needs.
@@codeblocks4067 The time and effort it takes to get it right is definitely not worth it unless you need custom belt dimensions on short notice. But great results can be achieved while keeping it as thin/flexible as possible with near zero stretch.
Inspired by this video, I recently printed a 3M timing belt with 140 teeth from PA6/66 (some kind of co-polymer from a local filament manufacturer). Two walls only x 0.45mm width, no gap fill. It was for my parents bread making machine. It came out incredibly strong and runs smoothly for about a month now... I didn't expect this to work this good, this material has extremely good layer adhesion. The best I ever seen...
@@MyTechFun If you decide to try PA, consider soaking the belt in water for a few hours. You will see a result in a very positive direction... Also if your model is with the accurate dimensions, you can add 0.5% shrinkage compensation. Otherwise it will came out smaller... I suspect that polyethylene would be also a suitable material for timing belts, but I didn't have a chance to try it.
All results advance knowledge, so it’s great to see a channel that does thorough testing - even if it helps us to learn what doesn’t work. Liked, subscribed and looking forward to more.
Important update for 2.5.0 PrusaSlicer users: Print Settings / Layers and perimeters / Perimeter generator: turn from Arachne to Classic. Turn off Fill gaps. Cura users: Sorry, new 5.x currently don't want to print those two lines continuously. Can't find the solution so far, except to use older 4.x version.
It's cheating I suppose....but you could build more outside walls to the spine of the belt. It would make a thicker and more stiff belt, but it would also resist elasticity.
Maybe you can wrap the outside of the belt , with silk string or something, and glue it on, maybe a flexible adhesive , can glue it on, and be a protective layer externally! It should prevent stretching,. Or possibly print a smooth outer layer, that can be stretched slightly, before being glued on the inner portion , that is wrapped glued, then glue the outer layer onto the belt! It would be closer to production belts,
Just like anything else this has it's own use too. To me this looks like a very nice way to get a timing belt for cheap to use in diy projects... considering it's limitations of course. Thank you for this idea.
I printed a timing rack and it works perfectly. I even put sides on the design so the belt sits inside the rack (For added strength) and the rack slides inside the aluminium extruded. Ps, the rack only slides when first installed, then fixed firmly before operation.
I tried, vase mode is nice, only when it finishes first few layers. About material, I got several suggestions to try Nylon (or CF Nylon), it is flexible if printed only with 2 walls. We will see soon.
@@MyTechFun You do need to set both top and bottom layers to 0. With only a single wall, PLA becomes surprisingly flexible, although you of course trade in strength somewhat. The extrusion / wall width allows some control over that tradeoff.
Also regarding random seam - stringing can be removed by setting keep head over part during travel/move. 🤓 At least in cura that can be done, but do not recall the settings name. 😕
@@TheStuartstardust That's the combing settings; but the existing print tends to pull material out of the nozzle, so there is underextrusion at restart point.
I’ve had good luck printing traction tires for my model train projects out of TPU. Your project is intriguing as some of my engines use these types of belts in their drivelines. The torque is actually pretty low since these belts are on the motor side of the geartrain. There’s very little shock torque and almost no instant reversing so I’m thinking these could be durable enough for my application.
Carbon fiber tow would be best, as long as you keep it spread flat and thin so it remains flexible. Maybe wind the carbon around the belt and then connect the ends of the carbon to a battery to heat it and melt it into the plastic. Or could try microwaving it for a couple seconds.
Staying on the topic of belts that are easy to print and don't have too much demands on them, you could try(I dont print TPU and don't have it on hand, so at least not this time for me): 1) Printing them counting the elongation under load in. Should imporve stability, long term stability and also the teeth grip, so max torque. Thin segments of walls will elongate more than toothed segments, but a couple experiments should be enough to find out empirically good geometry. 2) The weakest point is obviously thin part of the wall, you could try making it thicker, like having teeth on both sides of belt in a sense, though back side teeth should obviously be not that pronounced. That could keep the belt flexible while making it tougher and should be printable. Might fail due to not enough wall adhesion though.
Super interesting! these diy belts probable need to be used together with larger pulleys, or as you said, with very small loads. But it does mean that you actually could print your own belts, and those belts could actually be usefull enough for something. This technically means that you could print the belts for a 3D printer, which is means that a 100% diy printed 3d printer is closer than ever before :)
Yes, probably there will be a second part of this video, testing Nylon (or even CF Nylon as comments suggested). Bigger pulleys and maybe even different tooth geometry.
Just stumbled across your video and liked the experiment very much. Nicely presented! I don't have a printer so I am less than a novice. But I would be curious to know if those belts would slip less if the teeth were a more square profile rather than round. From what you have said I don't know if this is possible with printer.
I mention in video that if I raise the wall thickness, I don't get holes between lines. In video from 6:00 . (presented in PrusaSlicer, but it exists in Cura 4.? too)
I like your thorough presentation even if I don't know enough to say whether your methodology is appropriate. As an alternative print design, can you please in a future video try printing open loop GT2 belt both upright and flat to the bed for comparison?
I'm thinking of using timing belts to drive the propellors in a rubber band powered model. The tension will be low so I think slightly stretchable belts might work well.
Thanks I have an Alfawise U10 printer that needed a belt like this to tie the two Z axis together. I hadnt figured out how to make this from a length of timing belt….Laurie NZ.
I really enjoyed your video. I don't find these useless. They can be improved. for example: Modifying the pulleys and the belts tooth (make them bigger and wider) and and pause the print a couple of times to insert some kevlar string (or textile fishing line) that was already tied in the length of the belt. Let's also not forget that the commercial belts are not made only of rubber. They would have the same properties if didn't had the reinforcing wire in them..
If it's within the resolution this application is dealing with, I wonder if square teeth would provide any noticeable amount more torque transfer than the sine-wave-ish pattern used.
actually there is belts with square teeth. Those got uneven load on the side of the teeth, which is why HTD and the GT profile is considered better than for example AT or T type belts. There's a lot of information about this when you read the spec sheets of belt manufacturers like Continental or Gates.
I would print that in something like Taulman 230, which is a very flexible but still very durable nylon. You can modulate the elasticity by adding two variable pumps on the backside. I am not sure about TPU, I use TPU for soft bumpers but not for anything durable.
Yes, I got several suggestions already to test Nylon (or CF nylon). I will, if there will be significant improvement I will create a video about it. If not, then only a post on YT channel.
@@MyTechFun I'd give a look at the Taulman 230 Nylon. The typical high strength nylons (I guess all CF variants included) are not that flexible. So they likely will suffer from the bending radius too much. The 230 one is a low temperature Nylon which is the most flexible I have used.
I just made a GT1 (1mm wide teeth/gaps) out of PETG. It's for a photographic printer. It's quite flexible and I managed to tweak the flow and temperature to avoid any gaps, strings or blobs. Will it last? Well, we'll see.
Looks like it would work well enough for an radio controlled car... I have uses o rings on vee (gears that were warn out so I cut v notch into them) and had great success...
Nice engineering. And thank you for wearing safety glasses, I find what a lot of UA-camrs do with now safety scary, especially for the younger folks that watch and learn bad behaviours.
Well done again! Is it possible to print a large belt in a small printer? It would be necessary to fold it a few times, and maybe put some supports to hold it until finished.
Softer nylon should have been tested as well as using thicker backplain on TPU printed belt. Additionally, some stretch assumption could be designed into the TPU belt to account for stretch putting the teeth into alignment instead of out of alignment with the cog pattern.
Filaflexible40 seems like it could be one of the better filaments for this. It's flexible but doesn't seem to stretch much and it also feels more grippy than most flexible materials I've seen.
Regular belts always have a filler of some kind. String or metal wires. If carbon fibre tpu exists, could that work the same? Is there another type of filament that has a single strand of material throughout the fillament?
Hi can you please explain this part of the script in the opencad script ? spiral_spacing = 4; // Distance between spirals spiral_inner_radius = 80; // Radius of the inner loop . thank you very much
Nice experiments. I wonder if it’s possible to pause the print midway so that reinforcements can be added. It might be difficult to get closed loop threads to use as the reinforcement material though.
Excellent as always! Thank you for your effort!.....Just one thought. After I see the experiment design, Its not important for me to see more measurements from each experiment. Id rather hear you discuss the summary results rather than see the measurements being taken. I think in this way the video would be shorter and more informative.

Supposedly TPU is compatible with PETG (for bonding) so perhaps with multi material printer you could embed PETG reinforcement.
It would be better to reinforce it with nylon. But this suggestion may be interesting too. Thx
To avoid seam line, maybe you could use "spiralize the outer counter" mode on cura. Also called "Cura Vase Mode."
Impossible with multiple walls
I tried spiralize, but only with 1 wall. Not good, since first few layers are not spiralized. The transition looks ugly.

results are not surprising because the main part of a timing belt is not a teeth but the stretch-resistant core which your belts are lacking.
