AUTOMATED 3D MANUFACTURING CONSTRAINT VALIDATION

Evaluates CAD geometry against 3D printing constraints: identifying steep unprintable overhang angles (>45°), wall thickness below nozzle limit (<0.8mm), and disconnected floating regions.

OVERHANG TEST THIN WALL TEST FLOATING ISLANDS
PRINTABILITY TEST REPORT: [FAIL] Overhang angle > 45° at Z=8.5mm [FAIL] Thin wall (0.4mm) detected at X=30mm [FAIL] 1 Floating region detected without support
