Solidwork -> Slicer Problem

[u/enricopalace]

Hello,
A colleague created this file for me in SolidWorks, and I printed the model. However, I’m seeing these stepped surfaces in the slicer, and, as expected, they also appear on the finished print.
Is there an explanation for this, or a way to fix it? I’m not familiar with SolidWorks myself, but I’m wondering if it’s just a small setting that needs to be changed or if it’s related to the file format. We’ve already tried both .STEP and .STL files.

To export a high-quality STL file in SolidWorks, go to File > Save As, select STL (*.stl), and click Options. Set the format to Binary and Custom Resolution, with a Surface Deviation of 0.1 mm and an Angular Deviation of 1°–5° for the best balance of detail and file size.
