See it before you print it

Preview3D opens 3D models and G-code the way Quick Look opens a PDF -on a Mac, an iPad, an iPhone and Apple Vision Pro.

Point your camera at the code and this Low-poly Mannequin Head stands on your own table in AR, at the size it will actually print. Nothing to install: it opens as an App Clip, shows the model, and leaves.

Check the fit before the filament. See how big a print really is next to the shelf it is meant for.

Open what can't preview. STEP, painted 3MF, STL, OBJ, glb, glTF, FBX and about a dozen more - plus G-code with a layer slider.

Thumbnails in the Finder and Files, so a folder of downloads stops looking like a folder of blank pages.

Publishing a model yourself? Make the same animation for it at preview3d.xfanta.com/qr - paste your model's link and get a QR code and a ready-made GIF for every file in it. Free, and it runs in your browser.
