The STL (Stereolithography) format is the standard for 3D printing, used to describe an object's geometry as a triangle mesh. Converting STL to USDZ lets you view your 3D models in augmented reality directly on iPhone, iPad, or Apple Vision Pro.
Launch Eyemesh and open your STL file: drag and drop the file into the window, or use File > Open (Cmd+O). STL files contain no textures — the model will display with a default material.
Inspect your model in the 3D view. Check that textures and materials display correctly. If textures are missing, use the Texture Manager to reassign them manually.
Click the export icon in the toolbar, select the USDZ format, choose a save location, and confirm. The USDZ file is ready — you can send it via AirDrop to an iPhone or embed it on a website.
STL (Stereolithography) is a format created by 3D Systems for 3D printing. It describes only the surface geometry of an object as a triangulated mesh, with no color, texture, or material. Available in ASCII or binary, it is the most widespread format for additive manufacturing and rapid prototyping.
USDZ is a 3D archive format developed by Apple in collaboration with Pixar. It packages a USD file with all its textures into a single uncompressed file. It is natively supported by iOS, iPadOS, macOS, and visionOS for augmented reality display via AR Quick Look.
