Product overview

What makes 42Maker different

It combines prompt-driven part creation with the controls you need to keep refining printable geometry inside the same editor.

Editable AI CAD

Start with a prompt, then adjust the result with object-level editing, transforms, and direct property controls.

STL Remixing

Import existing STL meshes and keep working on them in the same workspace as your native objects.

Print Checks

Run print readiness checks before export with build-volume and quality thresholds visible in the app.

Built for Printable Parts

Use screw tools, snap tabs, sketch extrude, sketch revolve, and edge finishing for real part workflows.
