STL & 3D Model Viewer - Mes3D

View, inspect, and explore 3D models directly on your Android device. Mes3D is a fast and lightweight 3D model viewer built for opening common 3D file formats and inspecting mesh-based models with smooth touch controls.

OPEN 3D FILES INSTANTLY
Import models from your device storage, cloud drives, or other apps. Mes3D supports popular 3D formats including STL, OBJ, glTF, GLB, 3MF, and PLY — ideal for 3D printing files and CAD exports.

SMOOTH 3D CONTROLS
Rotate, pan, and zoom with intuitive gestures. Inspect your model from any angle with quick view presets: front, back, left, right, top, and bottom. Switch between perspective and orthographic projection.

BUILT FOR 3D PRINTING WORKFLOWS
Mes3D focuses on accurate mesh rendering for tessellated geometry — perfect for checking STL files before slicing. View exact model dimensions (width, height, depth in mm) and triangle count at a glance.

MODEL ANALYSIS
Get volume, surface area, and estimated print weight for common filament materials. Check print readiness indicators such as open edges and non-manifold geometry before you print.

DISPLAY OPTIONS
Toggle wireframe mode to inspect mesh structure. Customize background and model colors, including a full custom color picker. Enable auto-rotate for a hands-free turntable view.

YOUR MODEL LIBRARY
Save imported models locally and reopen them anytime from a clean grid library with real 3D preview thumbnails.

SNAPSHOT & SHARE
Capture images of your 3D models and share them for documentation, review, or collaboration.

WHO IS MES3D FOR?
• 3D printing enthusiasts checking STL files before slicing
• Engineers and designers reviewing CAD exports
• Students and educators exploring 3D geometry
• Makers and hobbyists managing a 3D model collection

PRIVACY FIRST
All processing happens locally on your device. Your models are never uploaded or shared externally.

TECHNICAL NOTE
Mes3D focuses on mesh-based (tessellated) model rendering. Some advanced scene features such as animations, complex materials, or full scene hierarchies may not be fully supported depending on the file format.
