AI STL Generator

AI STL Generator is a web-based tool that converts 2D images and text prompts into watertight, slicing-ready 3D printable STL files in under 60 seconds. It is built for makers, print farms, and hobbyists who need clean, print-ready geometry without manual mesh cleanup in tools like Blender or Meshmixer.

Key Features

• Image to STL: Upload JPG or PNG photos, concept art, sketches, or logos, and the AI reconstructs depth, volume, and topology into solid STL models. Multi-image upload is supported for more accurate reconstruction from multiple angles.
• Text to STL: Describe an object in natural language, from tabletop miniatures to desk organizers, and the engine generates detailed solid meshes.
• Automatic mesh repair: Every output is remeshed and repaired to fix non-manifold edges, inverted normals, and zero-thickness walls, guaranteeing watertight geometry.
• Print-optimized output: Models are engineered for FDM and resin printers, with flat bottom geometry for bed adhesion and minimal support requirements.
• Export formats: STL and GLB files for 3D printing and visualization, with STL and OBJ direct export.

Workflow

1. Input your idea via a text prompt or a 2D reference image, selecting a detail level (Low Poly, High Poly, or Functional).
2. The AI generates the 3D geometry and runs automatic topology repair for watertight, manifold solids.
3. Download the STL file and import it directly into a slicer, ready to print without third-party repairs.

Compatibility

Generated files import directly into Bambu Studio, Cura, PrusaSlicer, OrcaSlicer, Creality Print, and ideaMaker with zero geometry errors.

Who It's For

The tool serves FDM hobbyists, tabletop gamers, Etsy shop sellers, and STEM educators, with use cases including custom miniatures, keychains, plaques, and classroom 3D printing projects.
