About

STL Viewer

Features
Read full description

STL View is an offline STL viewer, OBJ viewer, 3MF viewer and 3D model viewer for iOS. Open, inspect and share STL, OBJ or 3MF files for 3D printing and CAD-export workflows without uploading your models or creating an account. OPEN STL, OBJ AND 3MF FILES View binary and ASCII STL files Open geometry-only Wavefront OBJ models Open 3MF models, including project files exported from slicers Open models from your device using the iOS Files app or supported Open With and Share flows Reopen recently viewed models from your local Recent Files list Share a model only when you choose WORKING WITH 3MF 3MF is the 3D Manufacturing Format written by most modern slicers and CAD tools. STL View reads the geometry inside a 3MF package so you can check a part before you print it: Real-world units are read from the file, so dimensions are exact without choosing a unit Modifier meshes and negative volumes are left out, so what you see is the part itself A 3MF that holds only print data, such as G-code, says so instead of opening empty Print settings, plates, thumbnails, colours and materials inside a 3MF are not read INSPECT 3D MODELS Explore your 3D models with clear, responsive touch controls: Orbit and rotate models from any angle Pan, zoom and fit the model to the screen Switch between shaded and wireframe viewing Use perspective or orthographic projection Jump to front, back, left, right, top and bottom views Check model dimensions and triangle count Review mesh geometry before using it in a 3D printing workflow BUILT FOR 3D PRINTING AND CAD EXPORTS STL View is useful for: 3D printing enthusiasts checking STL or 3MF files before slicing Engineers reviewing mesh exports from CAD software Designers inspecting model dimensions and geometry Makers previewing downloaded 3D print models Students learning about 3D meshes Anyone who needs a focused STL, OBJ and 3MF file viewer LOCAL AND PRIVACY-FOCUSED Your models are processed locally on your device. STL View does not upload your model files, filenames, paths, geometry, dimensions or triangle counts to a cloud service, advertising provider or analytics platform. No account or registration is required. Recent-file copies and preferences remain on your device and can be removed from the app. RESPECTFUL VIEWING EXPERIENCE STL View keeps the 3D model at the center of the experience. The app does not use timed, interstitial or full-screen advertising flows. When advertising is enabled, only a banner may appear after a model is ready. SUPPORTED FORMATS STL - binary and ASCII OBJ - geometry only 3MF - geometry only, with units read from the file OBJ material libraries, textures and sidecar files are not loaded. Colours, materials and print settings stored in a 3MF are not loaded. Native CAD formats such as STEP, STP, IGES, IGS, Parasolid, SOLIDWORKS and Fusion files are not supported. Export those models to STL, geometry-only OBJ or 3MF before opening them. STL View is designed for viewing and inspection. It does not edit, repair, slice, convert or print models. Complex meshes may be displayed using a clearly identified reduced-detail preview. Open your STL, OBJ or 3MF model and inspect it from every angle with a simple, private and focused 3D model viewer.
