Convert Your 3D Mesh/Model FBX Files to 3MF

Our free and fast tool will convert most 3D mesh or FBX (Autodesk Filmbox) model files to a standard 3MF (3D Manufacturing Format) 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 FBX files; up to 25 files at a time can be converted.

To convert your FBX file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a 3MF file and will be ready for download shortly afterwards. For more information about the FBX to 3MF conversion process, see the conversion information section below.

Frequently Asked Questions

How can I convert my FBX file to 3MF?

First click the "Upload..." button, select your FBX file to upload. Select any configuration options. When the FBX to 3MF conversion has completed, you can download your 3MF file straight away.

How long does it take to convert my FBX to 3MF?

We aim to process all FBX to 3MF 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 FBX to 3MF 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 FBX to 3MF on ImageToStl.com?

Yes, of course! We do not store the FBX file you submit to us. The resulting 3MF file, once created is deleted 15 minutes after upload and the download link will expire after this time.

Can I convert my FBX to 3MF on Windows, Linux, Android, iOS or Mac OS?

Yes! Our FBX to 3MF 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 FBX 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.

What version of FBX file is supported?

Our tool can read binary FBX versions 7.0 and above and text formatted FBX files version 6.4 and above. Please ensure your FBX version meets these requirements before uploading.

I have several FBX files; can I batch convert my FBX to 3MF?

Yes! Our FBX tool supports full batch conversions. You can upload up to 25 and FBX files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the 3MF files individually or download them all in a single ZIP file.

File Format Information for FBX to 3MF

Extension	FBX
Full Name	Autodesk Filmbox
Type	3D Model
Mime Type	application/octet-stream
Format	Text & Binary
Tools	FBX Converters, 3D Model Voxelizer, Create FBX Animation, FBX Asset Extractor, Text to FBX, FBX Viewer

Description

The FBX format by AutoDesk was originally developed by Kaydara in the 1990s as a means to store 2D or 3D content with motion data. It has evolved over the years to become a widely used format by 3D modeling applications such as Blender, 3D Studio Max, and others due to its 3D animation capabilities.

The format is used to contain 3D models, which include vertices, faces, and other 3D geometry along with animation data. The format is proprietary; however, there is a publicly available API to use for development purposes. The file contents can be either text or binary, and work has been carried out by the Blender Foundation to document the format.

FBX Notes

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

Description

3MF files are a modern 3D file format designed specifically for use with 3D printable models (additive manufacturing). It was designed to be the successor to the popular legacy STL format (also a common format in 3D printing) to overcome the limitations of that format.

The format of 3MF files is XML-based and compressed with standard Zip file compression, resulting in small, easily transferable files. The format supports 3D meshes along with associated materials and textures, all contained within the Zip file.

3MF Notes

3MF files support material and color information. If your uploaded model contains color information, our tool will attempt to save this in the 3MF file at the end of the conversion process. Textures are supported and will be included in the final 3MF file.

Converting Your FBX File for 3D Printing

Software used to prepare a 3D model file for printing, which is also known as 3D slicer software, cannot usually open FBX files. This is because slicer software authors will support the most common formats used for 3D printing, such as STL and 3MF and do not have the resources to implement 3D object parsers for all the possible 3D formats that are out there.

Slicer software can, however, handle files formatted to the 3MF standard. This is because the 3MF format was specifically designed as a medium of storage and exchange for 3D printable models. Our FBX to 3MF conversion tool can convert your FBX file into a 3MF file suitable for loading into most 3D slicer software. As 3MF files support material colors and textures, our converter will convert these if present, resulting in a single 3MF file suitable for use with most 3D slicer software.

How does it work?

Converting from the FBX file format to 3MF 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 FBX file to a valid 3MF 3D model. Let's start with the conversion process, which involves the following steps:

Step 1: Read the Source FBX File

In its simplest form, an FBX file can be either a plain text or binary 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, normals, materials, and textures, as this is the only data that can be accurately converted into the final 3MF file.

The FBX file can contain data such as material definitions and textures that describe how a particular set of 3D geometry should be rendered. As we are creating an 3MF file, which supports both materials and textures, our tool will attempt to load any materials and textures present in the FBX file.

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

Step 2: Process File Data

With the FBX 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 3MF format.

⇪

Step 3: Saving to the 3MF Format

The 3MF file format is relatively new and its primary aim is to become the standard for storing and distributing 3D models for 3D printing applications. Most modern 3D printing software can open 3MF files.

Our tool will now take the in-memory 3D model we have created in step 2 and convert this to the 3MF format ensuring it is compatible with any 3D printing software that supports 3MF.

Along with the completed 3MF file, any textures that were present in the original FBX file will be saved in either PNG or JPG format, depending on the original image format. If the original format was neither of these, for example, if your model contained a texture in the TGA format, it will be converted to a PNG.
