Convert Your 3D Mesh/Model GLB Files to AMF

Our free and fast tool will convert most 3D mesh or GLB (Graphics Language Transmission Format) model files to a standard AMF (Additive Manufacturing File) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple GLB files; up to 25 files at a time can be converted.

To convert your GLB file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a AMF file and will be ready for download shortly afterwards. For more information about the GLB to AMF conversion process, see the conversion information section below.

How to Convert your GLB to AMF Online?

Here are two simple steps to convert your GLB to AMF.

Upload a GLB

Click the "Upload a GLB File" button and select a GLB to upload. The maximum file size is 100MB.

Download your AMF

Click the download link once completed to receive your AMF file.

Frequently Asked Questions

How can I convert my GLB file to AMF?

First click the "Upload..." button, select your GLB file to upload. Select any configuration options. When the GLB to AMF conversion has completed, you can download your AMF file straight away.

How long does it take to convert my GLB to AMF?

We aim to process all GLB to AMF conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.

How accurate is the GLB to AMF conversion?

We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.

Is it safe to convert my GLB to AMF on ImageToStl.com?

Yes, of course! We do not store the GLB file you submit to us. The resulting AMF file, once created is deleted 15 minutes after upload and the download link will expire after this time.

Can I convert GLB to AMF on Windows, Linux, Android, iOS or Mac OS?

Yes! Our GLB to AMF tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

What if I am using an Ad Blocker, will that affect things?

Yes. Although you can use an Ad Blocker, if you like our GLB conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.

I have several GLB files; can I batch convert my GLB to AMF?

Yes! Our GLB tool supports full batch conversions. You can upload up to 25 and GLB files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the AMF files individually or download them all in a single ZIP file.

Description

The GLB file format, which can also have the GLTF file extension depending on whether the content is binary or text/JSON, is a 3D file format used to describe 3D worlds and, as such, contains geometric data such as vertices, faces, normals, animations, and other 3D scene-related data.

The format, described by its creators as the "JPEG of 3D", has gained in popularity and is supported by a wide range of 3D modeling applications such as Blender and MeshLab. The GLB format is an open standard that is maintained by the Khronos Group.

GLB Notes

If your GLB file contains texture files and other texture-related data, these will be included in the conversion process.

Description

The AMF, or additive manufacturing file format, is an open standard 3D file format primarily used within additive manufacturing processes such as 3D printing. The initial release version of the file was in 2011, and the format continues to be developed today.

As this is a 3D file format, the contents, which are XML-based, describe one or many 3D objects broken down into solid volumes defined with vertices and triangles. The format has support for color and texture materials.

How does it work?

Converting from the GLB file format to AMF can be a complex process, and any tool used for this conversion process needs to be able to handle a variety of data conversion tasks as well as identify any defects within the 3D model and fix them. Here we will explain the conversion process used by our tool to accurately convert your GLB file to a valid AMF 3D model. Let's start with the conversion process, which involves the following steps:

Step 1: Read the Source GLB File

In its simplest form, an GLB file is a binary data file containing 3D data such as vertices, faces, normals, and more. When combined, these make up the 3D model you see on your screen.

When our tool reads this 3D data, all we are interested in are the vertices, faces, and normals, as this is the only data that can be accurately converted into the final AMF file.

The GLB file can contain other data, such as material definitions and textures, that describe how a particular set of 3D geometry should be rendered. As we are creating an AMF file, which does not support materials and textures, we will be ignoring this data if it is present in the GLB file.

For more information regarding the GLB file format, please see this great article that goes into a lot of detail explaining the GLB format.

Step 2: Process File Data

With the GLB file data read, our tool generates an internal representation of the full 3D model and will attempt to fix any geometry issues encountered. Along with repairing any issues with the 3D model, the tool will remove any duplicated vertices and prepare the model for exporting to the AMF format.

Step 3: Saving to the AMF Format

With the conversion process entering its final stages, our tool now needs to take the in-memory 3D model we have created in step 2 and convert it to the AMF format.
