Hello @Kava ! Thank you for your interest in SAMSON. As far as we know, no one is currently working on the STL exporter. But this would be a really nice feature. For the efficiency and speed reasons, the Gaussian surface is generated on GPU. Therefore, we don't have direct access to resulting shapes and it won't be that easy to export these shapes. We will see what we can do.
Another possibility is to program the Gaussian surface on CPU yourself and export the resulting shape in the STL file (see Documentation for developers).
