3dSynth

What is 3dSynth?

3dSynth is a revolutionary generative G-code engine designed for creative 3D printing. Unlike traditional workflows that require creating a 3D model (STL), repairing it, and then configuring a slicer, 3dSynth streamlines the process by generating toolpaths directly from mathematical rules. This approach allows artists, designers, and makers to create organic vases, lampshades, and intricate sculptural prints with unprecedented control and ease.

Key Features of 3dSynth

3dSynth stands out by bypassing the traditional mesh-based workflow entirely. Instead of fighting with mesh repairs and slicer settings, your printer receives instructions generated directly from parameters you control. Here are the core features that make this possible:

• Direct G-code Generation: There are no intermediate STL files, no mesh repair, and no slicer settings to configure. Toolpaths are computed mathematically from your design parameters, ensuring precision and direct control.
• Parametric Control: Every aspect of your form is defined by numbers you can tweak. Adjust frequencies, amplitudes, and phases, and watch the shape respond in real-time. This parametric control is ideal for creating unique, mathematically driven designs.
• Modular Effect Stack: Layer multiple effects to create complex surfaces. You can add ripples, blobs, noise, twists, and more. Each modulator can be precisely ranged to specific heights, allowing for sophisticated and layered designs.
• Real-time Preview: The 3D viewer updates instantly as you design. You can inspect layers, measure dimensions, and catch potential issues before you even start printing, saving time and filament.
• Spiral Vase Mode: Specifically designed for continuous Z printing, this mode creates single-wall vessels with organic textures and translucent effects. It is perfect for creating vases, lampshades, and decorative objects.
• Printer-ready Output: 3dSynth exports G-code configured for your specific machine. It includes built-in profiles for popular brands like Prusa, Bambu Lab, Creality, and Voron, along with proper start and end sequences.

How 3dSynth Works: From Idea to Print in Three Steps

The workflow is designed to be intuitive and requires no modeling software:

1. Define Your Profile: Use the spline editor to draw your base shape. By controlling the radius at different heights, you create the silhouette of your object.
2. Stack Modulators: Add effects that modify the toolpath. This is where you can get creative by layering ripples, noise, polygons, and blobs. Each modulator transforms the geometry in a specific way.
3. Export and Print: Download G-code that is ready for your printer. Load it directly into your machine. No post-processing is needed; the file is complete and optimized.

Who is 3dSynth For?

3dSynth is built for individuals who want direct control over their toolpaths and are looking to explore new creative possibilities in 3D printing. It is particularly valuable for:

• Artists and Designers: Those exploring form through mathematics and code will find 3dSynth to be a powerful tool for generative art.
• Makers: Individuals who want more control than traditional slicers allow can use 3dSynth to fine-tune their prints at a fundamental level.
• Creative Technologists: Experimenters in the field of generative fabrication will appreciate the direct G-code manipulation.
• Anyone Tired of the Standard Pipeline: If you are frustrated with the STL-slicer-print pipeline, 3dSynth offers a refreshing and efficient alternative.

Pricing

3dSynth offers a free browser version with generous features, allowing you to try the tool before committing. The browser version includes the profile spline editor, up to 4 modulators, 15 free effect types, real-time 3D preview, and G-code export.

For users who want the full experience, the Premium version is available for a one-time fee of €39. This unlocks the desktop app (Win/Mac/Linux) with all 31 effect types, unlimited modulators, the Julia Stack fractal mode, and lifetime updates.

Frequently Asked Questions (FAQ)

What printers are supported?

3dSynth generates standard G-code that works with any FDM/FFF 3D printer. Built-in profiles are included for popular machines, and you can also configure custom printer settings.

How is this different from a slicer?

Traditional slicers convert 3D models (STL/OBJ) into G-code. 3dSynth generates toolpaths directly from mathematical parameters—no 3D model is needed. This gives you precise control over forms that would be difficult or impossible to model conventionally.

Do I need 3D modeling experience?

No. 3dSynth uses a different approach: you define shapes through profile curves and stackable effects. If you can adjust sliders and see results in real-time, you can use 3dSynth.

What can I create with it?

3dSynth excels at vases, lampshades, decorative vessels, and sculptural objects. The spiral vase mode creates single-wall prints with continuous Z movement—perfect for translucent effects and organic textures.

Is the G-code safe to print?

Yes. The generated G-code includes proper start and end sequences for your printer, with heating, homing, and cooling commands. Print time and filament usage are estimated before export.

Can I use prints commercially?

Absolutely. Once you purchase a license, you own full rights to anything you create and print.
