I have a model that has a short section where the wall thickness is .523mm from Fusion360:

When I go to slice it, S3D will not print that wall.

Here are my Thin Wall Behavior settings.

I am printing with a .6mm nozzle. But even if I switch to a .4mm nozzle, it still will not print.

Only if I reduce the Extrusion with to .25mm will it print that wall, but even then its printing it as 2 shells and not a single extrusion.

What am I missing?

Here are all my settings. I tried added each as a separate pic inline, but apparently the limit is 3 for attachments:
(Sorry, I misspelled Width in the 04mm photo)

Thank you for posting this! Can you please post a Factory File so we can look into it further?

It's easy!

You have a wall the model with a front and a backside. And both together have ~ 0.54 mm or 0.27 mm each one.
Undependend of your nozzle of 0.6 mm the perimeters will be printed when Layer Width is max 0,25 mm.

In this point S3D is sensitiv and will not print this area because in sum the bottleneck will have twice Layer Width.
The bottleneck is a doubling of the perimeters where only one perimeter is needed - mission impossible!

The front and the backside of the model is inevitably. Thats the same with news papers, as thin as possible it has 2 sides. The only solution to print it in a simple way is to interrupt the wall and set a only one strip with 0,5 mm width between the ends. But it needs to print with a Layer Width of also 0,5 mm imperatively.

I'm sure that further versions of S3D could print it but version 4.0 and later are not able for this .

I'm sorry, Version 4.0 and higher is also able to print it!

Attached is a factory file of just that section. I can't post the entire file because its not a public model. But I think this should be enough.

Thanks!
