Yup, I use Tinkercad and awful lot, mainly because it's web based, free, and not blocked by our work firewalls when I'm on this long tedious calls listening to knobjockeys who like the sound of their own voices and licking the piles of their bosses...

All looks cool, guess once you have it and learn its capabilities you find uses very easily.

You're limited by your imagination, and the limits of the machine and materials you are using.

For example, most FDM and resin printers create prints that are weak in the plane the layers are printed, as with force, you can separate the layers.  Sometimes you can reorient the model before printing to overcome, sometimes you have to redesign it with that in mind if you need the strength in that plane.  Sometimes, it just won't work.

It is fair to say Creality's latest and greatest is utter shite with TPU.

*sigh*

Do I get a cheap, small printer just for TPU?

Is it the printer, or the slicing SW? If it would print ok on you old machine, maybe use that?

I'm shooting in the dark really as I've never used anything other than pla.

Its the printer rather than the slicer, and seems Creality have done some serious messing with slicer profiles to help, but none quite work.  Seems I'm not alone either!

Fortunately, taken inspiration from some extruder mods (which then preclude other materials without adjustment), I've printed some easily removed shims, and initial testing is looking promising, along with some profile tweaks.


The old printer  - K1 Max - had to go sadly, due to space issues at TB Towers.  It was great when I had both of them here, I really caught up with the backlog of stuff I had to print!

Fair enough, I'm yet to find a use case for TPU (good job really, considering I also have a Creality machine)- do you use it for RC stuff?

[TheBoy]

I have lots of uses for TPU.  Yes, great for camera mounts that are going to hit walls and drops at 50mph, but also make good lids for boxes printed in PLA as they tend not to come off when upside down in backpack.  I get a feeling our suitcase labels are TPU as well, with our initials and phone number on.

I did buy a pack of 5 rolls from Amazon back during that strange 2 years when the chinky sniffle was rife, and 4 of the reels still have some left on, though I've got through many more rolls of black since.

Pretty certain the Ender series support it well, except the Ender v3 and v3 Plus (which are sort of CoreXY, turned on its side). Other Ender 3's officially do list as being compatible, including SE's and KE's, but there are so many variants, I can't keep up! Can't remember which one yours is?
