About this 3D viewer
Read the XML metadata inside a 3MF package locally before printing or sharing. This inspector checks model units, object and build counts, package resources, texture files, color resources, and thumbnails without uploading the source file.
3MF files from Cura, PrusaSlicer, Bambu Studio, and CAD workflows
Use a current browser on Windows, macOS, or Linux to visually inspect compatible 3MF packages from Cura, PrusaSlicer, Bambu Studio, Microsoft 3D Builder, or a CAD export. Use the target slicer for printer profile, materials, supports, and final production validation.

3MF viewer FAQ
What does 3MF Metadata Inspector show?
It reads compatible 3MF XML and package paths to report units, objects, build items, resources, textures, color resources, and thumbnails.
Does it validate printer profiles or slicing settings?
No. Use Cura, PrusaSlicer, Bambu Studio, OrcaSlicer, or your target slicer for printer, material, support, and production validation.
Is my 3MF uploaded to a server?
The metadata report is generated locally in your browser after the one-time format unlock.
Can I preview a 3MF file from Cura, PrusaSlicer, or Bambu Studio?
Yes, for compatible geometry and available color data. This browser preview does not replace the slicer’s printer-profile, support, material, or print-preparation checks.
What file extension does 3MF use?
This tool accepts the compatible 3MF extension shown in the upload area. Use the dedicated format viewer when a file has a related extension or an application-specific variant.
Can I use this 3MF viewer on a phone?
The page can be opened on mobile browsers, but a desktop browser is usually more practical for large files and detailed orbit, zoom, and inspection work.
Do I need to create an account to preview a 3MF file?
Yes. Sign in first, then unlock this 3MF tool once for $1.90. VIP members can also access the viewer.
