Our story / Where it all began

It all started
with baking.

Five years of creating. A new chapter of building.

Before FlowTheory SD had a name, I started making cake toppers and cookie cutters for my wife's baking. Almost five years of 3D printing later, learning Fusion 360 has opened the door to custom automotive parts, practical prints, and personal creations.

The name began as a random idea: a way to put one name behind everything I make. Now it's how I'm taking years of learning and designing to the next level.
