AI Make · a build journal

I use AI to design things, then 3D print and build them to see if they work.

AI and I think it. I build it. The real world decides.

Reward Rocket

A tabletop rocket that releases one sealed reward capsule for my son Lucca. The video has the highlights. The page has the long version: the dead ends, the fixes, the files and every part I used.

About

Hi, I’m Mauricio.

I’m a mechanical engineer. I’ve founded, led, and sold companies in digital surgery and medical 3D printing. On my own time I use AI to go from idea to object, then find out if it survives.

AI is changing everything. It lets me make things I never thought possible, so I’m sharing the journey: timed builds, real stakes, learning by doing. Not a tutorial. Not a review. See how I work →

Your idea

Suggest the next build

Tell me what you’d like to see AI design. I read every one, and if I build your idea I’ll credit you in the video.
