Fusion 360 - How can I increase the polygons on a cylinder?

cwalsh561 — Tue, 18 Oct 2022 18:34:22 GMT

I've designed a smokebox for a model locomotive which looks great in Fusion but the cylinder has flats. Is there a way I can increase the polygon count to make a smoother print?

Hi @cwalsh561

Did you create a polygon sketch or circle sketch?

It was a circle sketch which I extruded over the inner shell.

Hi,

unfortunately the download was not allowed or you are using a personal license that does not include this option.

Please share the file this way:

Thanks for sharing the model.

Are you using Fusion 360 for printing or some other software?

Hi,

These are the results in Prusa Slicer at different resolutions.

I usually export an obj or an stl file and then slice it in Lychee slicer for the resin printer.
The Prusa settings on the Fusion file are there just because there is no setting for Lychee slicers or, indeed, ChituBox.
Best regards,

Hi,

The result in the slicer depends on the quality of the exported file.

The exports as 3mf (STL gives the same results) were made in Fusion in the specified resolutions.
Any slicer should accept these formats.

Thanks Gunther,
I've increased the resolution as you suggested and the results in the slicer look great.
Best regards and thanks again.
