Has anyone been able to, or does anyone know if you can, print the tires “by object” on a Bambu Lab P1S? I have tried, but whenever I place two or more tires on a plate in “by object” mode, I get an error message that the parts are too tall and will collide. I’m hoping someone has found a way to do this on a P1S.
The max I can do on my A1 is two tires and I have to put them front to back. On a core machine think about it, the bed has to raise all the way up to start printing the second tire, so yes the first tire would then be two tall.
Correct me if I’m wrong.

That makes sense. Never thought of it that way. Thanks for the input. I guess I’ll have to keep removing the strings from my tires or print them one at a time.
When you have time, there are a few threads on TPU. There is a very helpful TPU profile on Makerlab, Perfect TPU Profile. That and a little AI help, I no longer have any stringing on my tires printing on my A1, I print 3 at a time in about 20 hours. So I start every morning. Wake up, remove, restart…repeat …lol
I only have one machine, so 20 hours for 3 tires would really slow down making the TMT. I use Bambu Lab TPU 95A HF, and printing one at a time takes 2 hrs 18 mins. with Avoid Crossing Walls turned on, all with no stringing. If I do 8 at a time, it takes 17 hrs. 10 mins. with a lot of stringing that takes me about 1.5 hrs. to clean up. If I do them 3 at a time, it takes 6 hrs 42 mins. with a lot less stringing, but still about 3-5 mins per tire to clean them up.
You can’t do tall objects on enclosed core xy printers because the objects will collide with the top of the printer. print by object is easier to accomplish with bedslingers since you don’t have that limitation.

The most I can do by object on my P2S is 2. But, they come off perfect every time and zero clean up!
I have yet to get a clean one if I print by layer if I do any more than one.

So here’s what I’m doing at this point to get good quality tires with decent speed and not a lot of clean up work. I’m using Bambu Lab TPU 95A HF filament for high speed on a P1S. Because I can’t print “by object” on the P1S, I print 4 tires at a time placing them as far apart as I can in the 4 corners of the build plate (to make any stringing thinner because any excess heated filament gets stretched thinner over a greater distance), with the tire tread sides facing the corner of the build plate and the back side of the tires (which don’t show when the TMT is assembled) facing toward the center of the build plate. I use the standard Bambu Lab TPU 95A HF settings, plus “Avoid crossing wall”. The fronts of the tires come out great. There is some thin stringing for the most part on the parts of the tires that don’t show, and all of which can be removed with my fingers only (because they are so thin) in under a minute per tire. The print time is just under 9 hours, so all 16 tires and clean up now come in at under 37 hours.

Your using the PETG profile for TPU? Just want to make sure that wasn’t a typo. I use the Bambu TPU 95A profile when I print Priline 98A and it comes out flawless. TPU dried for 12 hours in AMS-HT and printed on a P1S.

with that filament try the 95a HF profile. Works perfect for me and 4 times faster!
I’ll try it on the next, I was scared to try it because the regular 95A printed so good lol.

No. The PETG was a typo. I’m using Bambu Lab’s TPU 95A HF for the tires. Thanks for catching this. I’ve fixed it in the post.

I get that for sure. But I promise I have printed a few spools of that and the CHCKX 98a on that profile and it prints perfectly. Oddly enough I messed up and printed some Ziro 95a on it as well and it didn’t miss a beat! So now that brand stays on that profile as well lol. I’m all about saving time when I can!
