About This Tool
AMF is an additive manufacturing format designed specifically for 3D printing, capable of storing color, material, and surface information. This viewer lets you open AMF files directly in your browser and see the model's colors, textures, and details instantly, with no software to install. It is a convenient way to check a print before it goes to the machine.
Tips
- 1Drag and drop an AMF file, or click to upload
- 2Display colors, materials, and surface details in real time
- 3All processing is done locally, so your files stay private

- Description:
- AMF (Additive Manufacturing File Format) is an XML-based open standard for 3D printing, developed by ASTM. It extends STL by adding support for color, materials, textures, gradients, and repeating units, aiming to serve as a modern replacement for STL. It supports multiple geometric representations and allows embedding print-related metadata in the file. Despite its technical advantages, AMF's ecosystem is far less mature than STL or 3MF: most slicers have incomplete support, and models may lose color or material information during toolchain transfer. The de facto modern standard in the 3D printing community today is 3MF, while AMF appears more in academic and early color printing scenarios.
Notes:
- The AMF format is widely supported in 3D software and engines
Supported Features:
- Real-time WebGL rendering
- Orbit controls with rotate/pan/zoom
- Wireframe and shaded display modes
- Animation playback (if supported by format)
How to Use
1
Upload Model
Drag your AMF file onto the page, or click to select a file. If you have associated textures, package them into a ZIP and upload together.
2
View Model
Drag with the mouse to rotate the model, scroll to zoom, and inspect the appearance, colors, and animations from any angle.
3
Done
Your files are processed only in your browser. No data remains after you close the page.
Frequently Asked Questions
View all FAQsQ
What is the difference between AMF and STL?
A
STL only describes the surface geometry of a model, while AMF also carries color, material, and curved-surface information. AMF is the better choice when your 3D print needs a detailed appearance.
Q
Can colors and materials inside an AMF file be displayed completely?
A
Yes. This viewer reads the color and material data stored in the AMF file and shows it directly in the preview, so you can inspect how the model will look before printing.
Q
What should I do if an AMF file will not open or looks wrong?
A
Make sure the file follows the standard AMF format. Some software exports AMF with uncommon syntax, so try re-exporting the model and then drag it into the preview again.
Q
Are curved surface details in AMF models displayed accurately?
A
Yes. The viewer renders directly from the surface information stored in the AMF file, producing smooth curved details that are useful for checking the model's appearance.
Q
What should I do if my slicer does not support AMF files?
A
Convert the AMF file to a slicer-compatible format, such as STL, using modeling or slicing software. Keep in mind that converting to STL removes colors and materials, so confirm the appearance in this preview first.
Q
Is AMF still widely used, or should I choose 3MF instead?
A
AMF is an older open standard that supports colors and materials, while 3MF is a newer standard with broader support in current slicers and software. You can preview both here and decide which format fits your printing workflow best.
