TPU90A Grippy Tire CAD published (Finally)

Yes hub material matters dont use straight up PLA, use PLA carbon .ix. or better yet if available print on MarkForged with black onyx. If you print using PLA Carbon make sure you are using a steel printer nozzle or a highly harden nozzle

I tried to cast a mould to pour copies of the original wheelā€¦ Didnā€™t turn out well. :frowning:

Oooo photos please

I tried to find it for photos, but no luck :disappointed:

Would 95U work? Namely
SainSmart TPU Filament 1.75mm, GT-3 Flexible 3D Printer Filament for High-Speed Printing 500mm/s, UV Resistant, Blue, 2.2 LBS (1KG) Spool, Dimensional Accuracy +/- 0.04mm Amazon.com

It would work, but i donā€™t think you would be happy with it. In my experience, high flow tpus tend to have some additive that makes then horrible for these kinds of wheels

Thanks for the info. I have printed one out of 95 because thatā€™s what I had for a test. I will buy some 90 and give that a print.

What sort of accuracy did your friend get?

Printed the @MrJacksDad5090 version on my BambuLab A1 mini. Took about 11 hours and print quality seems pretty good. Excited to test on our robot this offseason.

We had great results running just the tread version of that wheel this season since there were no field bumps to worry about. We do plan on running that design this year if the field has any bumps

printing some of the tread version right now to test out. itā€™s nice that itā€™s a lot faster print.

What filament are you using? We actually found the recycled tire made by Treed. Itā€™s kinda expensive but found it to be worth the cost. We found that a set of tread would last through qualifying and probably would last a little longer but would switch to a fresh set for playoffs

Gonna test with amolen tpu since itā€™s relatively cheap. Might check out the stuff from treed tho.

We only found one place selling it in the US and that is Hartland. Weā€™ve been ordering it from Filament2print located in Spain. The price is cheaper but shipping is more. We figured out as long as you order 2 or more rolls from the place in Spain that it works out cheaper and arrives pretty darn quick too. The only thing with that filament is it is very stinky, actually smells like burning rubber so we relegated to the mentor printing at home so the school wouldnā€™t complain

do you happen to know what flow rate and speed settings were used? and yā€™all printed them on an X1C, right?

I think the generic tpu bambu setting were used. @MrJacksDad5090 would know for sure.

Thor was right - just the generic TPU settings on an X1C using the engineering plate.

what times were you getting? currently iā€™m at around 5 hrs for the tread and like 11 hrs for wheel with suspension. i think iā€™m doing like 4 walls and 30% gyroid infill for tread.

Iā€™m getting an access denied error with these links. Could you re-share?
