An imported STEP file is converted to a triangle mesh on import (making it much like a typical .stl or .3mf file) which means that slicing all happens as one would normally expect.

Find out what is an STL file and how you can open and view an STL file with .stl extension in Windows 10. It is native to the stereolithography CAD software.

Step 5: Slicing your file with Desired Settings Into a G-code File Slicing a file means preparing a CAD model for turning it into a G-code file that 3D printers can make use to create an object.

If you’ve ever wondered why designers like to work with STEP files and not STL, this video answers that question immediately. A part brought in from a STEP file is closer to the original CAD object.

Stereolithography (STL) is the standard file type for our 3D-printing software. A mesh resolution of 0.01 to 0.03 mm and a ≤0.016-mm chord length produce an optimal STL file.
