You can use our USD to STL conversion tool to quickly and easily convert your 3D model files for free. You may upload up to 20 files at one time, and our batch USD to STL converter will process each 3D model and present you with a download link for each file once completed.
Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.
Our 3D model USD to STL tool will load your USD 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.
Here are two simple steps to convert your USD to STL using our fast and free USD converter tool.
First, click the "Upload..." button and select your USD file to upload. Your USD file will be uploaded to our servers. When the USD to STL conversion has completed, you can download your STL file right away.
We aim to process all USD to STL conversions as quickly as possible; this usually takes around 5 seconds; however, this can be longer for certain files, so please be patient.
We aim to provide the best conversion experience. Our tools are under constant review and development, with new features being added every week.

USD files are a 3D model format designed specifically for the exchange of 3D data between different systems within a standard and easy-to-implement format.
Within a USD file are the various data elements that make up the 3D model, including vertices, faces, normals, and texture coordinates. Along with this basic geometry, other important information is stored, such as camera and other environmental properties.
Support for exporting 3D content to the USD format can be found in certain 3D modelling applications, such as Blender, Maya, and Houdini.

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

The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modelling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.
STL files come in two flavours: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.
The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.
STL Converter Capabilities
When converting your USD to STL, our tool will attempt to accurately convert any colour or material information.
Your USD file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our USD 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals, and relevant material information. As both USD and STL support colour material information, our tool will also attempt to convert the colour information.
