STL Viewer – 3D Model Viewer
Offline STL 3MF OBJ 3D Viewer
Free · Designed for iPad. Not verified for macOS.
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.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Picking a model no longer fails with "The selected file is no longer available." Files chosen from the Files app, iCloud Drive, or sent over with Open With or Share now open as they should STL, OBJ and 3MF alike.
Opening a second model right after the first no longer leaves the previous model on screen under the new file's name.
The app now opens on a dark screen with its icon instead of flashing white.
