Trying to get a faster print time with a larger nozzle
Trying to lower the print time on this object but when I set up the printer (MK3S) with a .8 nozzle and do the slicing I still get 7 days for this object
Am I doing something wrong or is because that it is basically a hollow cylinder
Thanks

Did you figure it out? I see you responded to your own post.
RE: Trying to get a faster print time with a larger nozzle
Just a guess, but did you ammend Extruder1/Nozzle diameter in Prusaslicer.

Without seeing what it is you're trying to print and—most importantly—seeing your settings (upload a zipped 3mf project file), it's absolutely impossible to help in any meaningful way.

How do I upload the project file?
Do I need to store it on the web somewhere and post a link?
RE: Trying to get a faster print time with a larger nozzle
Compress it (right click on Mac or Windows), then use the Attach file button here below the edit window to upload the .zip file (forum software insanely only accepts zip, not 3mf).

Hopefully this works - could mot find an 'Attach file button' but did find 'Add Media'

Attach file button:
Regarding your model: Well, you're printing TPU, which prints at a snail's pace. This, together with a large object, yeah, that'll take a while. Plus, 60% infill. Absolutely no need for it. With 15% you're down to 4 days. The limiting factor with TPU is maximum volumetric speed. In your profile it's set to 1.8, which feels low. I'd give it a try at 4.0 which brings print time now down to 1d20m, without any other optimization.
And my three tips for printing TPU: Dry the filament. Dry it more. Dry it again and print from the dry box.

RE: Trying to get a faster print time with a larger nozzle
The value that is limiting the speed is the filaments Max Volumetric flow setting. The thing is with TPU it will HAVE a low volumetric flow. Its the nature of the material. But with that big a nozzle and that big a layer height it might be possible to up the volumetric limit. That's one of those things that you would have to do some smaller test prints with your setup and the intended material to test to see what your actual practical limit is before the extruder can't cope. Once you know the limit, knock it back 10% and set that as your new limit value. There are tutorials on how to test max volumetric flow rates.
I am surprised its got a 2mm retraction over ride though for the filament. I would have thought tpu would have minimal to no retraction as it really doesn't like retraction.
What I would comment on is does it really need 60% gyroid infill ? I'd also turn off ensure vertical shell thickness and thick bridges. Personally Id also increase the perimeter count to 3 and reduce the infill %, but that's just me, and more in line with my normal settings for prints. With 3 perimeters and 30% cubic the print time drops to a smidge over 6 days, even with the volumetric at 1.8.
Large objects like you have take LOTS of time. Get used to it as its normal with most 3d printers, especially so with tpu which is one of the trickier materials to print.

Thanks fuchsr and Neophyl for the answers
I'll play around with some of the suggestions
If what we are printing works in the field - 7 days will not be that much of an issue / might just buy another i3 and have my own small small 'printer farm'
