Insights Where Digital Meets Physical Mechanical engineers become indispensable as they bridge the gap between digital models and physical reality. 3D Printed Tooling The future of tooling and what it means for design and production at small scale. Good Decisions, Wrong Order Why most product rework isn't caused by mistakes, and what to do about it. The Four Rules Foundational principles of Convergent Design. The Constraints Nobody Chose Some constraints are decisions nobody remembers making. Rank them. Who Holds the Pen Every constraint has a discipline best suited to own it. Let them hold the pen.
