STL 3D Format

STL Converter

The Stereolithography (STL) format is one of the oldest and most widely used 3D formats. Primarily used for 3D printing, it is supported by virtually every 3D printing and slicing program, making it a popular choice for general 3D printing needs. If you’re unsure of a format to use for printing, STL is a safe bet until you know exactly what you want.

You can open STL files in Blender, MeshLab, Fusion360 and many other programs, and the format works across Windows, macOS, Linux, and even mobile platforms. If you want to store material or colour data in your file, however, you may need to look for an STL alternative, as this format only supports geometry data. For mocking up quick prototypes, though, you can’t get much better than STL, with its minimalism and near-universal support.

USD 3D Format

The Universal Scene Description (USD) file format is an open-source 3D format created by Pixar for handling scene data for films, animations, and special effects. It was designed to manage massive, complex scene data across the entire production pipeline, with useful features for collaboration and non-destructive editing. The USD format supports both ASCII and binary encoding, with the ASCII version ideal for human readability, and the binary format best when you need compact files that are space-efficient for storage and sharing.

USD files are supported by many programs, including Houdini, Blender, Unreal Engine, Maya, and Apple AR tools. They can be used on Windows, macOS and Linux, and their wide compatibility makes them ideal for the collaborative projects they were designed for. This format does have a very high learning curve, however, so using an easier-to-parse format may be better if you’re not in the VFX business.
