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.
Refine your prints in the tools you already use
Export print-ready STL and OBJ files for Cura, PrusaSlicer, Bambu Studio, and any slicer.
Why makers choose Sloyd for 3D printing
Unlimited Generations
Paid plans give you unlimited AI generations, so you can iterate on every miniature, prop, and gift until it prints exactly right.
From Prompt to Print-Ready in Seconds
Describe what you want or upload a reference. Sloyd returns a watertight, manifold STL or OBJ you can drop straight into your slicer.
No CAD, No Cleanup
Skip the modeling software and the mesh-repair step. Sloyd optimizes geometry for printing automatically, so you go from idea to plate without the busywork.
Built for makers, start to finish
Print in full color across multiple filaments, add keychain loops and mounts, and split big models into parts that slot together, then export watertight files for Cura, PrusaSlicer, Bambu Studio, or any slicer.
Multicolor Prints
Reduce a textured model to a set number of colors, from 1 to 16, and print it in full color instead of painting it by hand afterwards.
Keychains, Pendants, and Mounts
Add a keyring loop, pendant, wall mount, or display stand to any model. Sloyd seats it on the base and welds both into one solid STL or 3MF in millimeters.
High-Precision 500K-Triangle Meshes
Generate dense, watertight meshes with up to 500K triangles, so fine detail and smooth curves survive on the print instead of turning into flat facets.
Multi-Filament Support
Map each model color to a filament slot on your multi-material printer, then export a color OBJ or send it straight to OrcaSlicer.
Split into Parts with Connection Points
Slice a large model into printable pieces. Attachment points add a pin on one part and a matching hole on the other, so the printed parts slot together.
Everything you need to go from idea to print
Text and Image to STL
Type or upload an image to generate a 3D printable object. Ideal for miniatures, house decorations, tabletop figures, pendants, and jewelry.
Presets optimized for 3D Printing
No more menu diving. We ensure you get the best quality, optimized for printing, and in the appropriate scale.
Keychains, figurines, and other prints
What makers print with Sloyd: things to carry, display, and give away, from one prompt or photo.
AI Keychain Generator
Generate a character, pet, or prop, then add a keyring loop in Mounts & Keychains. Sloyd scales the model to keychain size and seats a loop sized for a real split ring.
- Model scaled to 45 mm on its larger footprint side
- Loop stays at real size to fit a standard split ring
- On figurines, the loop sits on top, usually on the head
Miniatures and Display Pieces
Turn a character sketch or prompt into a detailed miniature that holds up on the shelf or the game table. Print one hero or a whole set for your next campaign.
- Up to 500K triangles for fine detail
- Start from a prompt, a photo, or a sketch
- Add a display base in Mounts & Keychains
Pet Figurines from a Photo
Upload a photo of your pet and Image-to-3D turns it into a printable figurine. Put it on a stand for the shelf, or add a loop and carry it on your keys.
- One clear photo is usually enough
- Keeps recognizable proportions and pose
- Works for pets, toys, and other real objects
Seasonal Decor and Gifts
Make Halloween props, holiday ornaments, and one-off gifts from a prompt, a photo, or a child's drawing. Generate a matching set in one style and print the whole collection.
- Start from text, a photo, or a drawing
- Keep a whole set in one style
- Print-ready STL in under a minute
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.
