A closer look at your 3MF.
Inspect geometry, check dimensions, and explore every placed object.
Model files stay in your browserHow local processing works
01
Open your model
Choose a 3MF or try our two-instance sample. Your file stays in this browser.
02
Explore the geometry
Drag to rotate and scroll or pinch to zoom. Check the size and placed instances.
03
Continue when you’re ready
Move to the converter with your current model, or clear it to start again.
Geometry first. Project settings stay behind.
| IN YOUR 3MF | IN YOUR STL |
|---|---|
| Triangle geometry | Preserved, with transforms applied |
| Object positions & scale | Preserved as millimeter coordinates |
| Colors, materials & textures | Not included |
| Slicer settings & project structure | Not included |
The preview uses a neutral blue material. It does not reproduce the project’s original colors, textures, or toolpaths.
Understand the format differences →A few things to know
One file at a time. Up to 50 MiB compressed, 200 MiB expanded, and 1 million expanded triangles. Device memory can impose lower practical limits.
This tool checks readable geometry and dimensions. It does not repair meshes or certify a model as printable.
