Select File(s)

Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.

Please note: Your AMF file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted AMF file before this time.

Our 3D model AMF to 3MF tool will load your AMF file and, where supported, attempt to extract all the relevant 3D features, such as geometry, textures, and animations. To access the 3D conversion configuration options, click the button when you have selected your files. The current options support the ability to voxelize your 3D model and more.

First, click the "Upload..." button and select your AMF file to upload. Your AMF file will be uploaded to our servers. When the AMF to 3MF conversion has completed, you can download your 3MF file right away.

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

We aim to process all AMF to 3MF conversions as quickly as possible; this usually takes around 5 seconds; however, this can be longer for certain files, so please be patient.

How accurate is the AMF to 3MF conversion?

We aim to provide the best conversion experience. Our tools are under constant review and development, with new features being added every week.

How does converting AMF to 3MF work?

In order to successfully convert an AMF formatted file to the 3MF format, our converter tools will perform several initial checks to ensure the file provided is indeed an AMF file. There are many files out there where the file type extension does not match the data contained within the file. Along with these file type checks, our tools will do additional checks to ensure the file is correctly formatted to match the provided file type. There are many tools out there that do not always create AMF files to the exact specification.

Take your AMF file

The AMF file format is a text-based format, meaning its contents are human-readable, making AMF files easy to edit in simple text editors. Within this text-based format are the core elements that make up the 3D model, including vertices, faces, and more. To ensure efficient conversions, our tool will check all data that is contained within the AMF file and remove any information that is duplicated. This not only ensures the conversion completes more quickly, but also the generated 3MF file size is smaller.

Convert the data from AMF to 3MF

Now that the data from the AMF file has been processed, our tool can apply any conversion specified options, such as enabling Voxel mode, and with these applied, prepare the data to be converted to the final 3MF file format. Part of this process ensures checking the capabilities of the 3MF format and removing any data that cannot be represented.

Save to the 3MF format

At this point, the AMF to 3MF conversion tool will have the 3D model in a state that is ready to be transferred to the 3MF format. Our tool creates the 3MF file, ensuring all the model data is present and is formatted to match the 3MF file specification to ensure the file opens in compatible 3MF file editors.

File format information for AMF and 3MF

Extension	AMF
Full Name	Additive Manufacturing File
Type	3D Model
Mime Type	text/xml
Format	Text

The AMF file format, which stands for Additive Manufacturing File, is a common 3D model format used for 3D printing. An AMF file can contain multiple 3D models, stored in a manner that is suitable for use with 3D printers.

Each model within the file is stored as a series of vertices, faces, and material information that is needed when 3D printing a 3D object. Data within the AMF file is stored in XML format, making the data human-readable and also structured.

Although there are other formats used within 3D printing circles, such as STL and 3MF, There is still support for AMF files within many 3D printing slicer applications, and our own AMF conversion tools allow converting to and from this useful format.

When converting 3D model or mesh files using our AMF converter, we will attempt to convert colour materials into a suitable format for use in the converted file.

Extension	3MF
Full Name	3D Manufacturing Format
Type	3D Model
Mime Type	application/vnd.ms-package.3dmanufacturing-3dmodel+xml
Format	Binary

The 3MF file format was created as a standard storage medium for 3D models for use within the area of 3D printing. A 3MF file will contain 3D model data stored within an XML-formatted document with additional assets such as image previews and material data. These files are wrapped up within a compressed ZIP file (using the 3MF extension).

The 3MF format was created in response to the constraints of the STL format, which is the most popular format for storing 3D printable models. Unlike the STL format, which can only store triangular information, the 3MF format can store mesh geometry along with material, units of measurement, and other relevant 3D printing information that is impossible to store within an STL file.

Storing the 3D data within a ZIP file container ensures the file size is kept to a minimum while making it easily extendable in the future. 3MF files are widely supported by 3D printing slicer software and are a common export option within 3D editing software.

When converting your AMF to 3MF, our tool will attempt to accurately convert any colour or material information.

Information for converting from AMF to 3MF

Your AMF file will be converted to a 3MF file using our unified 3D model and mesh conversion tool. Our AMF 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals, and relevant material information. As both AMF and 3MF support colour material information, our tool will also attempt to convert the colour information.
