Why is flat colors 3D model sharp when cut?

Flat-color 3D models stay sharp when cut because solid, unshaded colors preserve clear edges—no lighting or texture blending softens cross-sections. This sharpness comes from the absence of gradient details: each face retains its distinct color, so cut lines don’t blur from extra visual information. For projects like 3D printing, keeping topology clean (even edge loops) helps maintain sharpness; do a quick mesh check before slicing to avoid unintended smoothing.
