STL Viewer – 3D Model Viewer

STL View is an offline STL viewer, OBJ viewer and 3D model viewer for Android. Open, inspect and share STL or OBJ files for 3D printing and CAD-export workflows—without uploading your models or creating an account.

OPEN STL AND OBJ FILES

• View binary and ASCII STL files
• Open geometry-only Wavefront OBJ models
• Open models from your device, file manager or supported “Open with” and Share flows
• Reopen recently viewed models from your local Recent Files list
• Share a model only when you choose

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 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 and OBJ file viewer on Android

LOCAL AND PRIVACY-FOCUSED

Your 3D models are processed locally on your device. Model files are not uploaded to our servers.

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

OBJ material libraries, textures and sidecar files 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 or geometry-only OBJ 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 or OBJ model and inspect it from every angle with a simple, private and focused 3D model viewer.
