Harv3d turns your photos into layered, multicolour 3D printable OBJ files - no 3D modelling experience required.

Whether you're a hobbyist, maker, or running a 3D print business, Harv3d does the heavy lifting. Import an image, let the app detect and map the dominant colours, assign layer heights, and export a ready-to-slice OBJ file complete with MTL colour data.

HOW IT WORKS

Import any photo from your gallery or camera
Harv3d automatically detects the dominant colours using perceptual colour analysis
Adjust layer heights, hide layers you don't need, and fine-tune the colour mapping
Preview your model in the built-in 3D viewer
Export an OBJ + MTL file ready for your slicer

KEY FEATURES

🎨 Intelligent colour detection - perceptual analysis finds the most visually distinct colours, not just the most common ones

🧱 Layered 3D model output - each colour becomes its own printable layer with individually adjustable height

👁 Built-in 3D preview - inspect your model with pinch-to-zoom, rotate, and pan before exporting

✏️ Edit mode - paint over misdetected areas to correct the colour mapping manually

📐 Base plate control - add an optional base layer for easier bed adhesion

📤 Universal OBJ export - compatible with all major slicers and 3D printing software
