A CLOSER LOOK
Open a 3MF model for a quick visual inspection
A 3MF package can contain model geometry, units, multiple objects, and appearance information. Open it here to rotate and inspect supported model content. Use your slicer to review printer-specific settings, material assignments, and the final print preparation.
Inspect before slicing
Get a visual overview of a 3MF model before preparing layers, supports, or toolpaths in your slicer.
Keep the package local
The selected 3MF file is read in your browser and is not uploaded to ImageTo3DPrint.
Good to know before you open a file
- A 3MF slicer project can include vendor-specific settings or extensions that this model viewer does not display. Linked model assemblies are not supported; export a single self-contained 3MF model.
- A preview does not apply printer profiles, assign physical filaments, generate toolpaths, or certify a successful print. Compressed files are subject to additional memory and safety limits.

A LITTLE MORE TO KNOW
Questions?
Let’s make it clear.
Practical answers about viewing your files.
How is 3MF different from STL?
STL primarily stores a triangular surface. A 3MF package can also store units, several objects, colors, and other printing information, depending on the software that created it.
Will the viewer show all settings in my slicer's 3MF project?
No. The viewer displays supported model geometry. Printer profiles, supports, filament assignments, and vendor-specific project data should be reviewed in the slicer that created or supports the project.
Does opening a 3MF file start a print?
No. This is a visual model viewer. It does not connect to a printer, generate G-code, or send a print job.
