General Information

This guide is part of the RapidPipeline 3D Formats Knowledge Database. It shows how to convert 3MF to glTF, if you'd like to know more about the formats, please check out the following links:

Converting and Optimizing 3MF Files to glTF

There are various ways to convert between 3MF and glTF. With RapidPipeline, you can easily convert and and optimize 3MF files, at scale. It supports glTF, as well as many other file formats (examples: FBX, OBJ, PLY, STL, USD, USDZ, VRM), at high quality.

Below you can find a video explaining how to convert your files:

What are 3MF and glTF files commonly used for?

The 3MF file is a format mostly used for 3D printing and additive manufacturing.
The glTF file is a format mostly used for interactive 3D, on the Web and elsewhere (e.g., in XR).

Limitations of 3MF Files to glTF Conversion Workflow

The following limitations should be taken into account when converting 3MF files to glTF format:

3MF Feature (not supported by glTF)Limitation Details
Scene Composition

Scene Composition Support:

3MF: Full support | glTF: No support

Scene Composition illustratedlack of support for Scene Composition illustrated

Impact:

Scene Composition describes the process of composing a scene through links from a main scene that pull in various other scenes/3D models. This can also happen in a nested fashion (through multiple levels of linkage). With a target format not supporting this feature, references to external models must be resolved and the content be baked into one 3D model, which is then saved in that target format.

What's the best way to get 3MF files into my 3D applications, and are there alternatives to using glTF?

Doing 3D conversion right, especially at scale, can be tricky, as 3D data is in general a rather complex (yet very powerful!) medium. This also applies to 3MF and glTF files - the conversion guide above provides a rough first idea about that. Once you know what you would like to do, tools like RapidPipeline can help you perform the necessary steps, and to even automate the process for thousands or even millions of files.

Especially when introducing pipelines and workflows at scale in an enterprise context, it is usually good to rely on dedicated tools and expertise, making sure you do not introduce any steps into your 3D workflow that are detrimental to the final output's quality, or that take your team too much time (and money).

If you're interested to hire dedicated expertise from the best in the field to help your company reach your goals fast and reliably, please do not hestitate to contact DGG. Being the creators of RapidPipeline, and ambassadors for open 3D standards for more than a decade, we have been building some of the world's most advanced 3D pipelines, having processed many millions of 3D assets.

Therefore, our expertise will help you to reach your goals faster, at scale, and with the least possible friction, since we are focused on maximum interoperability.
