STL & 3D Model Viewer - Mes3D

Mes3D is a fast and lightweight 3D model viewer for Android. Open, inspect, measure, and organize STL, OBJ, GLB, glTF, and other 3D files directly on your phone or tablet.

Whether you are checking an STL file before 3D printing, reviewing a CAD export, or exploring a model in augmented reality, Mes3D provides smooth controls and practical model analysis tools.

Open popular 3D file formats

Import 3D models from your device storage, cloud drives, or other apps. Mes3D supports:

• STL • OBJ • glTF and GLB • 3MF • PLY • STEP and STP • FBX • DAE • USDZ • 3DS • AMF

Mes3D makes it easy to open common 3D printing files, mesh models, and CAD exports wherever you are.

Smooth 3D model controls

Explore every part of your model using intuitive touch gestures:

• Rotate, pan, and zoom • View models from the front, back, left, right, top, or bottom • Switch between perspective and orthographic projection • Enable auto-rotate for a hands-free turntable view

View 3D models in augmented reality

Place supported 3D models in your surroundings using your device camera. Tap a detected surface to position the model, pinch to resize it, and drag to rotate it.

Useful tools for 3D printing

Inspect STL files and other mesh-based models before slicing or printing. Mes3D displays essential model information, including:

• Width, height, and depth in millimeters • Triangle count • Model volume and surface area • Estimated print weight for common filament materials

Check mesh condition indicators such as open edges and non-manifold geometry to identify potential issues before 3D printing.

Inspect mesh structure

Enable wireframe mode to examine model topology and mesh structure more closely. Customize the model and background colors using preset options or the full color picker.

Build your 3D model library

Save imported models locally and reopen them whenever you need them. The clean grid-based library displays 3D preview thumbnails to help you find your files quickly.

Capture and share

Create snapshots of your 3D models and share them for documentation, feedback, project reviews, 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 organizing 3D model collections • Anyone who needs a practical 3D file viewer on Android

Technical information

Mes3D focuses primarily on mesh-based and tessellated 3D model rendering. Support for animations, complex materials, textures, or complete scene hierarchies may vary depending on the file format and model structure.

Open, inspect, measure, and explore your 3D models with Mes3D.
