The Ultimate Guide to Turn 3MF Files into SimReady USD Content

This guide is part of the RapidPipeline 3D Formats Knowledge Database.

3MF (3D Manufacturing Format) is an XML-based file format developed by the 3MF Consortium for additive manufacturing and 3D printing. Unlike traditional 3D formats that only describe geometry, 3MF is designed to capture the full intent of a 3D model including materials, colors, textures, and manufacturing instructions. The format addresses limitations of STL by supporting color, materials, lattices, and multiple objects in a single file. 3MF uses a ZIP-based package structure and is supported by major 3D printing software and hardware manufacturers including Microsoft, HP, Autodesk, and others. It is a file format mostly used for 3D printing and additive manufacturing.

USD (Universal Scene Description) is the primary format to generate SimReady data, enabling 3D assets to be used in simulation environments such as NVIDIA Omniverse, PhysX, and more. For this to work properly, USD assets must adhere to the USD standard, and ideally bring metadata that helps to inform downstream simulation use cases about various simulation-relevant properties of the 3D asset.

There are various ways to generate USD files, but especially when starting from non-simulation formats like 3MF, it is not easy to perform a good conversion. Additional required steps might include material assignment (in case realistic materials are desired) and related steps like UV generation, but also metadata transfer from the original file to the final SimReady USD asset.

With RapidPipeline, the process of generating NVIDIA SimReady USD content from 3MF files is easy:

1. Download RapidPipeline Twin Studio, or one of the RapidPipeline 3D tool plugins (free trial available). Alternatively, you can also use RapidPipeline directly in the browser.
2. Perform the conversion from 3MF to USD. Store or download the resulting USD file, it's ready to use!
3. If you'd like to scale up the process, simply get in touch to acquire a license for the RapidPipeline 3D Processor, running as powerful batch processing tool that turns your entire library of 3MF files (or other files) into SimReady USD content.
