AI 3D Printing
AI 3D Printing
Describe any part in plain English and get a 3D-printable STL file in minutes. No CAD software or experience needed.
Describe what you need and get a clean, watertight STL ready for your printer. Ragnar builds real B-Rep geometry first, then exports perfect meshes with no manifold errors. Iterate through conversation until it's exactly right.
No credit card required. 15 free credits monthly.
Skip the CAD learning curve
You don't need to learn SolidWorks, Fusion 360, or any modeling software. Describe your part with dimensions and features, then iterate through conversation. 'Make the walls thicker', 'add a snap-fit tab', 'round the corners at 2mm'. The AI updates the model in place. Export STL when ready and send it straight to your slicer.
Why B-Rep matters for 3D printing
Ragnar builds true B-Rep solids first, then converts to mesh for STL export. This means proper wall thickness, clean surfaces, and no manifold errors every time. Other AI generators create mesh directly, which often produces non-printable geometry that needs manual repair.
STEP export for more than printing
Need the same model in STEP for CNC machining or further editing? Ragnar exports that too, along with DXF for laser and plasma cutting. Every model starts as real CAD geometry, so you get both mesh and solid formats from a single description. Works with any 3D printer, any slicer.
Real Examples
See It in Action
Real prompts, real results. Watch how Ragnar CAD generates precise, editable models.
01
Minimalistic phone stand
AI generates a print-ready phone stand with cable management. Clean STL with proper wall thickness.
02
A wall rack that docks six shaker bottles
AI creates a 3D-printable bottle rack with six sized openings and wall mounting slots.
03
A ventilated enclosure for my electronics, snap-fit lid
AI generates a printable vented case with port cutouts. Print the base and snap-fit lid separately.
Why Ragnar CAD
Built for Real Engineering
Not a toy. Production-grade CAD geometry you can actually manufacture.
Clean, watertight STL files ready for your slicer
No CAD software or training required, just describe your part
Starts as true B-Rep geometry, so the mesh export is always clean and watertight
Iterate by conversation: adjust walls, add features, refine dimensions
Also exports STEP for CNC machining or professional CAD editing
