# 3DWebGen

> Free AI-powered platform for converting images and text into 3D models. Generate GLB and STL-ready files online.

3DWebGen is a web-based 3D model generation tool. Users upload images (PNG, JPG, WebP) or type text descriptions, and the AI creates downloadable 3D models. The platform supports single-image, multi-view (3 angles), and text-to-3D generation modes with optional PBR textures.

## Core Features

- **Image to 3D Model**: Upload a photo, drawing, or sketch and convert it to a 3D model
- **Text to 3D Model**: Describe an object in natural language and generate a 3D mesh
- **Multi-View 3D**: Upload 3 photos from different angles (front, back, left) for higher accuracy
- **AI Texture Generator**: Generate PBR materials (color, roughness, normal maps) on 3D models
- **GLB Export**: Download models in GLB format (binary glTF), the industry standard for web 3D
- **STL-Ready**: Convert GLB to STL for 3D printing using free tools or online converters
- **GLB to STL Converter**: Built-in browser-based GLB to STL conversion tool
- **OBJ to STL Converter**: Built-in browser-based OBJ to STL conversion tool

## Pricing

- Free tier: 15 credits on signup, no credit card required
- Each generation costs 5-30 credits depending on mode, quality, and texture options
- Paid plans available for higher usage (Starter, Pro, Enterprise)

## Supported Input Formats

- PNG, JPG, WebP images
- Text descriptions (natural language prompts)
- GLB/glTF files (for GLB to STL conversion)
- OBJ files (for OBJ to STL conversion)

## Output Formats

- GLB (binary glTF 2.0) - primary output, includes geometry + textures
- STL - via built-in converter or external tools, geometry only, ideal for 3D printing

## 3D Printing with 3DWebGen

3DWebGen is designed with 3D printing workflows in mind. The AI generates solid, watertight meshes with optional high-detail geometry and PBR textures, ready for slicing and printing on any FDM, SLA, or SLS 3D printer.

### Model Quality Options
- **Standard Mode**: Fast generation with clean, solid geometry suitable for basic prints
- **High Quality Mode**: Finer mesh detail, smoother surfaces, and more accurate geometry for detailed prints
- **Textured Mode**: Generates full PBR-textured models with color, roughness, and normal maps — ideal for multi-color 3D printers (Bambu Lab AMS, Prusa MMU) or for painting reference
- **High Quality + Textured**: Maximum detail with full texture maps — produces production-ready 3D models with both fine geometry and realistic surface materials

### Image to STL Workflow
1. Upload a photo, drawing, or sketch of the object you want to print
2. Choose quality settings: enable High Quality for detailed prints, Textured for color data
3. The AI generates a detailed 3D mesh with clean geometry (and textures if enabled)
4. Download the GLB file
5. Convert GLB to STL using the built-in converter at /glb-to-stl, or use any free 3D software
6. Import the STL into your slicer (Cura, PrusaSlicer, BambuStudio, OrcaSlicer, etc.)
7. Print on your 3D printer

### Text to STL Workflow
1. Describe the object you want to print (e.g., "a chess knight piece" or "a phone stand with cable hole")
2. Enable High Quality and/or Textured for better results
3. The AI creates a detailed 3D model from your description
4. Download as GLB and convert to STL
5. Slice and print

### 3D Printing Tips
- Enable **High Quality** mode for finer mesh detail, smoother curves, and more intricate geometry
- Enable **Textured** mode to generate models with full PBR textures (color, roughness, normal maps) — useful for multi-color printing or as a painting guide
- Use **Multi-View** mode (3 photos from different angles) for the most accurate geometry reconstruction
- Generated meshes are manifold (watertight) and do not require mesh repair in most cases
- GLB files can be imported directly into modern slicers like PrusaSlicer 2.7+ and BambuStudio
- Textured GLB files preserve vertex colors and UV-mapped textures for multi-material printers

### Supported 3D Printer Types
- FDM (Fused Deposition Modeling) - most common desktop printers (Ender 3, Prusa MK4, Bambu Lab, etc.)
- SLA (Stereolithography) - resin printers for high-detail miniatures and figurines
- SLS (Selective Laser Sintering) - industrial powder-based printers
- Any printer that accepts STL or GLB files

## Common Use Cases

- 3D printing: Convert images or text to printable STL meshes
- Game development: Generate 3D assets from concept art or descriptions
- AR/VR: Create 3D objects for augmented and virtual reality experiences
- Product visualization: Turn product photos into interactive 3D models
- Education: Generate 3D models for teaching and learning
- Rapid prototyping: Turn ideas into 3D models without CAD software
- Custom figurines and miniatures: Generate and print tabletop gaming pieces
- Replacement parts: Photograph a broken part and recreate it as a 3D printable model

## FAQ

### How do I convert an image to a 3D model?
Upload your image (PNG, JPG, or WebP) to 3DWebGen and the AI will automatically convert it into a 3D model. You can use Multi-View mode with 3 angles for higher accuracy. Download the result as a GLB file, ready to convert to STL for 3D printing.

### Is 3DWebGen free?
Yes, you get 15 free credits on signup with no credit card required. Each generation costs 5-30 credits depending on options.

### How does text to 3D work?
Type a natural language description of what you want (e.g., "a medieval sword with leather grip") and the AI generates a 3D mesh matching your description.

### What is the difference between GLB and STL?
GLB files contain geometry plus textures, materials, and colors. STL files contain only geometry. For 3D printing, use STL. For web, games, and AR/VR, use GLB.

### Can I 3D print the generated models?
Yes. All models are generated as solid, watertight meshes suitable for 3D printing. Download the GLB file, convert to STL using the built-in /glb-to-stl converter or any free 3D software, and import into your slicer.

### What slicer software works with 3DWebGen models?
Any slicer that supports STL files: Cura, PrusaSlicer, BambuStudio, OrcaSlicer, Simplify3D, and others. Some modern slicers also accept GLB files directly.

### Do I need to repair the mesh before printing?
In most cases, no. The AI generates manifold (watertight) meshes that are ready for slicing. If your slicer reports issues, use a free mesh repair tool like Meshmixer or the built-in repair in PrusaSlicer.
