UNLOCK YOUR iPHONE’S TRUE 3D SCANNING POWER. EXPORT FOR REAL-WORLD MANUFACTURING TODAY. Your iPhone 17 Pro is equipped with a world-class LiDAR scanner and ARKit Object Capture photogrammetry engine. But Apple locks your brilliant 3D scans inside the closed .USDZ and .Reality formats. You can view them in AR, but you cannot 3D print them, edit them in CAD software, or use them in game engines. USDZ to STL & OBJ Converter is the ultimate mesh translation tool. We break down the walls of the Apple ecosystem, allowing you to instantly convert your photogrammetry and point-cloud scans into universally accepted 3D printable meshes and UV-mapped 3D assets. THE "SCALE BUG" FIX (OUR SECRET WEAPON): Apple exports USDZ files in "Meters". If you blindly convert this to STL, your desktop slicer (like Ultimaker Cura or PrusaSlicer) reads it as "Millimeters". Your 20cm scanned object becomes a microscopic 0.2mm dot! Our advanced conversion engine automatically calculates and fixes the geometry scale. Your parts import into your slicer at the exact 1:1 real-world dimensions. Perfect for reverse engineering and mechanical fits! PROFESSIONAL CAPABILITIES: 1-Click STL Export (For 3D Printing): Generate watertight, manifold polygon meshes ready for FDM (Fused Deposition Modeling) and SLA Resin 3D printers. OBJ + Full Textures (For Game Dev & CGI): Need the photorealistic colors your iPhone captured? Export to .OBJ and we automatically package the MTL material files and High-Res Texture Maps (Color/Albedo) into a clean, shareable ZIP folder. 100% Offline On-Device Processing: Zero cloud uploads. Zero subscription fees. Your proprietary CAD designs, face scans, and room maps stay strictly on your iPhone. Powered natively by iOS Metal and ModelIO. Mesh Inspector: View live polygon counts and vertex data before you export. Ensure your mesh isn't too heavy for your slicer. COMPATIBLE WITH YOUR ENTIRE WORKFLOW: Our exported STL and OBJ files are guaranteed to work seamlessly with the industry's top slicing software, 3D printers, and 3D modeling suites: 3D Slicers: Ultimaker Cura, PrusaSlicer, Bambu Studio, Chitubox, Lychee Slicer, Simplify3D. 3D Printers: Bambu Lab (X1C, P1P), Creality (Ender 3, K1), Prusa, Elegoo, Anycubic, Phrozen. CAD & Modeling Software: Blender, Autodesk Fusion 360, ZBrush, Maya, Unreal Engine 5, Unity, Tinkercad, Nomad Sculpt, SketchUp. WHO USES THIS TOOL? Cosplayers & Prop Makers: Scan your body parts (face, arms) and export to STL to 3D print perfectly fitted custom armor and masks. Reverse Engineers & Mechanics: Scan broken car parts or household items, export the mesh to Fusion360, rebuild it, and print the replacement. Indie Game Developers: Use your phone as a cheap 3D scanner. Capture real-world rocks, trees, and props, export as colored OBJ, and drop them straight into Unreal Engine or Unity. Tabletop & D&D Gamers: Scan miniature terrain and print it for your next campaign. Stop letting file formats kill your creativity. Bridge the gap between iOS photogrammetry and desktop manufacturing.
