AI 3D Model Generator for 3D Printing
Stop wrestling with complex CAD software: Sloyd is the fastest way to create 3D print-ready STL or OBJ files directly in your browser. No modeling experience required.
Why choose Sloyd for 3D printing
Unlimited & Credit-Free
Generate and iterate without limits. Paid plans are not credit-based, so you can experiment freely until the model prints perfectly.
Print-Ready STLs & OBJs
Get models that actually print. Our "3D Print" preset ensures watertight, manifold geometry ready for your slicer.
Instant 3D models with AI
Skip the CAD learning curve. Just type a prompt or upload an image to generate a unique 3D model in seconds.

Frequently Asked Questions
Which file formats are supported for conversion?
STL is best for 3D printing (slicers like Cura or PrusaSlicer). OBJ is great for editing in Blender or Maya. GLB/glTF is ideal for web and AR/VR applications.
How fast is the conversion process?
Speed is a priority. Standard files typically convert in under 1 minute, though highly complex or high-resolution images may require slightly more processing time.
How accurate is the AI conversion?
Accuracy depends on the quality of the prompt or image and how much detail the print needs. Clear references, good lighting, and a focused subject improve results; you can iterate with new prompts or references until the model looks right for print.
Are the models watertight and ready to print?
Yes. When you use our "3D Printing" preset, our AI optimizes the mesh to be watertight (manifold) and solid, preventing common printing errors. We always recommend checking the model in your slicer for wall thickness.
Do I need to know CAD or 3D modeling?
Not at all. Sloyd is designed to be a "No-CAD" tool. You can create complex objects by typing a text prompt or adjusting simple sliders in the Template Editor. Much faster than traditional modeling for props, miniatures, and prototyping.
Does this tool work on mobile?
Yes. Our platform is entirely cloud-based and optimized for cross-platform use on Windows, macOS, Linux, iOS, and Android using any standard web browser.
Is Sloyd AI free for 3D printing?
Yes. Guests can convert and view 1 3D model every day. For unlimited conversions and downloads, sign up for a paid account.
