Practical guides for printable names
STL vs 3MF: which export should you use?
Both formats can carry your printable design, but they suit different slicer workflows.
Choose STL for broad compatibility
STL is a simple mesh format supported by virtually every slicer. Use it when you need one printable surface and the widest compatibility.
Choose 3MF for richer projects
3MF can keep multiple objects and separate colors together. Use it when your slicer supports 3MF and you want a more complete project file.
Check the sliced preview
Whichever format you choose, inspect the sliced layers and dimensions before printing.
