3MF Validator
Check a 3MF package for readable model entries, supported build items and mesh data before using it in a viewer or converter.
Workflow type: 3MF package validation report. Status: Functional. Expected result: Inspection report. Available action: Validate 3MF package.
What this 3D tool provides
Validate a local 3MF file online, inspect readable package resources and supported build items, and identify issues before conversion or printing.
- 3MF Validator brings 3MF input and the listed JSON report outputs into one review sequence.
- Use the before-and-after labels for orientation, then confirm the selected file with the result guidance and format notes below.
- Accepted input: 3MF.
- Available controls: Include build items and transforms in report, Include supported resources in report, Include supported mesh geometry in report.
- Review the readable package entries, model resources, build items and supported geometry conditions before printing, converting or sharing the file.
How to use 3MF Validator
- Choose a supported file — Choose 3MF from your device.
- Review settings — Review the available controls: Include build items and transforms in report, Include supported resources in report, Include supported mesh geometry in report.
- Review and download — Review the measured result and preview before downloading an available export.
Preview and result review
A multi-part build package makes resource, transform and supported geometry checks useful before it is sent to another tool.
- Before example: A selected multi-part 3MF build package
- After example: A validation report listing readable build items and supported package resources
3MF package validation report: Review the readable package entries, model resources, build items and supported geometry conditions before printing, converting or sharing the file.

Frequently asked questions
What does 3MF Validator do?
It reads the package entries, supported model resources, build items and transforms so structural problems are visible before a conversion or visual review.
Which files does 3MF Validator support?
Local .3mf manufacturing packages are checked and summarized in a JSON report.
Is my 3D file uploaded?
Supported file contents stay on this device while the selected tool runs; site analytics and the assistant are separate. The selected file is not uploaded for the supported processing workflow.
What should I review after using 3MF Validator?
The report does not certify printer-specific settings, material behavior, collision clearance, wall thickness or print success. Confirm those details in the intended manufacturing workflow.
