Unleash Your Creativity with Professional 3D Tools
Discover the advanced engineering behind Tessel Units that turns simple images into complex, printable puzzles.
Intelligent Pixel Conversion
Our engine doesn't just resize images; it understands color and structure to create the perfect pixelated foundation.
- Advanced K-Means algorithm for precise color quantization.
- Support for SVG, PNG, and JPG with instant processing.
- Customizable target width from 8 to 128 blocks.
- Real-time palette preview and manual color adjustments.
Precision 3D Engineering
We handle the complex geometry so you can focus on the design. Every puzzle is generated with physical assembly in mind.
- Adjustable tolerance (0.1mm increments) for the perfect mechanical fit.
- Dynamic base plate generation with customizable heights.
- Automatic block grouping: adjacent pixels of the same color are merged into single larger pieces.
- Smart 'islands' detection to ensure every piece is structurally sound.
Slicer-Ready Workflow
Go from digital design to 3D print in seconds. Our export pipeline is optimized for modern multi-material printing.
- Multi-material 3MF export: color data is preserved for AMS/MMU systems.
- Automatic Bed Splitting: creations larger than your printer are intelligently segmented.
- Native optimization for OrcaSlicer, BambuStudio, and PrusaSlicer.
- Detailed PDF assembly guides generated for every project.
Professional Design Suite
A dedicated workspace built for pixel artists and makers.
- Full layered canvas system (Base, Pixels, Overlay).
- Infinite undo/redo history and auto-save functionality.
- Custom Shape Editor: draw your own base plate masks.
- Cross-platform browser support with no installation required.
Community & Public Sharing
Tessel Units is more than a tool — it's a thriving maker community. Share your creations, discover others, and build your own public profile.
- Public gallery with advanced filters: dimensions, colors, shapes, and more.
- Public creator profiles — showcase all your published creations.
- Like system to save your favorite community models.
- Color-based filtering to find exact matches or palette-compatible creations.
AI-Powered Description
Give your creations the presentation they deserve. Our built-in AI generates a rich, engaging description tailored to each puzzle in one click.
- One-click AI description generation directly from the editor.
- Custom instructions to guide the AI tone, language, and style.
- Generated text is saved as semantic HTML — ready for the public page.
- All generated descriptions are tracked in your profile credit history.
Printer Calibration Suite
Stop guessing. Our calibration tools help you find the perfect fit for your specific printer and filament — before committing to a full print.
- Free clearance test file generator: test multiple tolerances in one print.
- Printer preset library: Bambu Lab, Prusa, Creality, and 2025/2026 models.
- Adjustable pixel size (4–20mm) and tolerance (0–0.5mm in 0.05mm steps).
- Double-row test plates to verify alignment and piece fit simultaneously.
AI & MCP Integration
Control Tessel Units with your favorite AI assistants (Claude, Cursor, etc.).
- Full Model Context Protocol (MCP) support.
- Generate and modify 3D models via natural language.
- Seamless integration with Claude and Cursor.
- Secure API access for your automated workflows.
Built for Makers, by Makers
Every feature in Tessel Units is designed to solve real-world 3D printing challenges — from calibration to community sharing and AI-powered design. We keep adding more.
