The CAD built for 3D printing.Easy to learn, powerful enough to grow with you.

Design your own parts, not someone else's

Downloading a model gets you close. Designing one gets you the bracket that fits your shelf, the insert that fits your drawer, the adapter nobody has uploaded. KapyCAD is built so that's a first-evening project rather than a semester.

• Open a browser tab — there's nothing to install
• Sketch a profile, give it thickness, print it
• Change a number and the part updates

Parametric from day one

Plenty of beginner tools let you push shapes around and then leave you stuck the moment a dimension has to change. KapyCAD gives you constraint-solved sketches and an editable feature tree from the start, so the file you make this week is still easy to change next month.

• Constraint-solved sketches
• Extrude, revolve, sweep, loft
• Fillet, chamfer, shell
• Booleans and patterns
• Named parameters with expressions
• Reusable Smart Objects: holes, heat-set inserts, magnet pockets, snap joints

Your printer and your material, in the model

Your printers, nozzles, quality presets and filaments live in the Workbench. Guided print-and-measure calibrations turn them into real clearances, so holes and fits are sized for the machine you'll actually print on instead of a generic guess.

• Printers, nozzles, qualities and materials in one place
• Guided clearance and printability calibration
• Your calibrated tolerances drive the geometry
• STL export, ready for your slicer

Guided tutorials, built into the product

The Academy walks you through the editor one step at a time, each step with a short clip of the real interface. You learn the tool by making something with it, not by watching a course first.

• Step-by-step guided tutorials
• Short clips of the real editor
• Reference articles on printing parts that fit, joints, and printers & materials
