The eternal engineering debate visualized with perfect clarity! On the left, subtractive manufacturing (like CNC machining) where you start with a block and carve away material until your part emerges—represented by a cool blue silhouette chilling in negative space. On the right, additive manufacturing (3D printing) where you build up material layer by layer—shown as a literal human-shaped inferno of creative potential.
Engineers secretly judge each other based on this preference. Subtractive folks pride themselves on precision and minimal waste, while additive enthusiasts won't shut up about "unlimited geometric freedom" and how they printed a fully functional whatever last weekend.
