# 3MF Viewer

Free online 3MF viewer. Open and preview 3D manufacturing files (.3mf, .amf) directly in your browser — no upload, no 3D software.

- **Category:** 3D Models

- **Supported formats:** .3mf, .amf

## Overview

This 3MF viewer renders 3D manufacturing files directly in your browser using WebGL. 3MF (.3mf) and AMF (.amf) are XML-based formats designed for 3D printing, offering richer data than STL — including color, materials and metadata. Pick a sample model or choose your own .3mf / .amf file to preview it in an interactive 3D viewport, with no upload.

## When to use

- You received a .3mf file from a 3D printing slicer and want to preview it.
- You need a quick, private preview of a manufacturing model.
- You want to inspect a 3MF model's color and material data.

## How it works

- Select a built-in sample model or choose your own .3mf / .amf file.
- The viewer loads the model with WebGL (three.js) in your browser — nothing is uploaded.
- Rotate, zoom and pan to inspect the 3D model.

## Use cases

- Previewing 3D printing models with color.
- Inspecting 3MF and AMF exports.
- Checking manufacturing models before slicing.

## Samples

- **Sample 3MF Model**: A 3MF 3D model sample for in-browser preview

## Frequently asked questions

### What is a 3MF file?

3MF (.3mf, 3D Manufacturing Format) is an XML-based 3D file format developed by the 3MF Consortium (Microsoft, Autodesk, Dassault and others). It is a ZIP archive containing XML model data, supporting color, materials, slices and metadata — richer than STL.

### What is the difference between 3MF and AMF?

Both are XML-based 3D printing formats. AMF (Additive Manufacturing File Format, ISO/ASTM 52915) came first in 2011 but had limited adoption. 3MF (2015) was created as a more practical replacement with broader industry support and richer features.

### Are my 3MF files uploaded?

No. Models you open from your device stay on your device and are rendered locally with WebGL. Only the public sample model is requested from the server.
