Open any 3D file in seconds, view it in AR with Apple Quick Look, and check it for 3D printing — no account, no sign-up, no cloud upload. Your files never leave your iPhone or iPad. Whether you're a 3D-printing hobbyist checking an STL before slicing, a 3D artist previewing a GLB or FBX, or a CAD user opening a STEP or DXF, Open3D Viewer opens it instantly — without the paywalls and login screens other 3D viewers force on you. SUPPORTED 3D FILE FORMATS • Mesh: STL, GLB, GLTF, OBJ, PLY, 3MF, FBX, DAE, 3DS, USDZ • CAD: STEP / STP, IGES / IGS, DXF Export & convert Turn OBJ, PLY, 3MF, FBX, DAE, 3DS and more into STL for 3D printing or GLB for sharing.

Two small pieces of feedback: there have been a couple .3MF that have been unable to render (but have also printed successfully). And a feature request to be able to view flat 3D files like DWG. -- sanspantalones, 2026-08-09 ### ***** "Looks good" Just getting started but looking good so far! -- Roku owner, 2026-07-11 [View all Open3D reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Open3D Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Free | Spain | Graphics Design | #130 | | Top Free | Israel | Graphics Design | #131 | | Top Free | Germany | Graphics Design | #163 | | Top Free | Czechia | Graphics Design | #174 | | Top Free | Hungary | Graphics Design | #185 | | Top Free | Australia | Graphics Design | #191 | | Top Free | United Arab Emirates | Graphics Design | #203 | | Top Free | Lebanon | Graphics Design | #213 | | Top Free | Netherlands | Graphics Design | #243 | | Top Free | Egypt | Graphics Design | #250 | ## Apps Similar to Open3D -
