3D Printing
Print-ready models from a description.
Generate watertight, slicer-ready STL and 3MF for FDM and resin printing — parts, enclosures, jigs and replacement parts from plain English.
Going from idea to printed part usually means learning a CAD package first. AiCadGen skips that: describe the part and download a manifold STL or 3MF that drops straight into your slicer. It is ideal for functional prints — jigs, fixtures, brackets, replacement parts and enclosures — where dimensions matter.

Why use AiCadGen for this
- Watertight, manifold meshes that slice without repair.
- Dimensionally accurate functional parts, not just decorative shapes.
- STEP also available if you want to refine the part in CAD before printing.
Example prompts
- $Replacement knob, 30mm, D-shaft 6mm, knurled grip
- $Cable clip for 8mm cable, screw-mount, snap fit
- $Drill jig for 5 holes at 25mm spacing on a 200mm edge
- $Phone stand, 60 degree angle, cable slot at the back
Frequently asked questions
Will the STL slice without errors?
Yes. Output is manifold and watertight, so Cura, PrusaSlicer and Bambu Studio accept it without mesh repair.
Can I get tolerances for press-fits and clearances?
Specify the clearance you want (e.g. "0.2 mm clearance for an 8 mm shaft") and it is applied to the relevant feature.
