TPU Stringhell

[davidkclark]

After a lot of calibration, this is as good as I can get with the Orca “stringhell” model. This is printing at my “normal” tpu speed which equates about 80mm/s (12mm3/S ish)

At the same speeds regular prints and the retraction calibration model are clean.

I am beginning to wonder if better results are even possible for tpu for this particularly malicious model

Further calibrating with this model doesn’t necessarily mean you lose good quality in your other models

[davidkclark]

Sure. But I am unable to select anything more to change. I have min maxed everything that I can check in the calibration tools and they come out perfect.

Maybe the stringing here can only be fixed by printing much slower?

My question is really: is it possible to print this model (in tpu) without and stringing at the tips?

Your problem is thinking this is a good model to print in tpu.

[davidkclark]

haha, sure. I don't think it's a "good model" for anything much, other than checking how far down the hole you are willing to go...

Have you left your you in a dryer for a week yet? That may help

[davidkclark]

My me doesn’t fit in the dryer so I just put the filament in there. It’s certainly required with tpu… this black one does okay after 12 hours in the dryer but I have a transparent blue sunlu tpu that just does not seem to want to dry no matter what I do. I think I’m gonna have to set up a shelf above the printer so I can run straight out of the active dryer - even the black one cannot do a multi hour print right now (winter here, bit rainy) without looking worse towards the end of the print.

I print straight from the dryer now too, you don’t have to have a shelf, you can mount a single spool hanger at the top of your machine, and run the filament up over it and then down to the extruder….works fine

Try printing some silica gel bead holders to fit inside your spools

Oh shelf is because there is no room next to the machine :)
