3D Printing Forum

Hi Everybody.
Has anyone used TPU filament, I was thinking of trying it.
I am worried about it being flexible and also how well the layer adhere.

Thanks in advance.

I've used Ninjatek Cheetah on my Ultimaker a few times. I printed super slow and got some really nice prints

Thanks Paul.
Any other advice on printing this soft material?
I've just been using PLA for so long I'm out of touch.

Hi LePaul

Lets talk about TPU, did you 3D Printer this with your Creality or another printer.

Thanks for the video Paul.
I'll let you know how I get on with TPU.

I bought a 500g SUNLU TPU 1.75mm.
These are the first samples 1.2mm thick cones. They came out very well.
Settings in Cura:
0.1mm layer 0.8mm wall thickness (no infill)
Temp 220C
Build plate 40C
Speed 20.0
Retraction-off
Retract at layer change-off
Cooling: fan speed 20%
No supports
Skirt.
Thanks to Paul for his video.

Isn't it weird to print without retraction?

Slow definitely works very well with this material.

2nd print.
Well I expected a little bit of stringing. I guess I'll have to do a bit of trial and error.

I did another print enabling retraction. and retraction at layer change.
Retraction distance 2.0
Retraction speed 15.0
Combing Mode, All.
As you can see the prints are a lot better.
I don't think I can get rid of the stringing but there isn't a lot.

Nice job!

Thanks Paul
TPU is a strange material. I'll be doing some more prints in this material when I get time. I'll let you know the results.
It would be better I think with a direct drive printer for TPU. I think that's what my next printer will be.

Yes, direct drive has been my preferred setup for a while now.
