Moldex3d Crack Top Updated Jun 2026

Twenty minutes later, the results were green. By stabilizing the thermal gradient at the top of the part, they had reduced the residual stress by 40%. The "Crack Top" was gone—theoretically.

| Fix | How to Implement | Expected Reduction | |-----|------------------|--------------------| | (≥ 0.5 mm) | Use CAD fillet tool on all 90° corners near the hot spot. | 30‑50 % lower peak stress | | Gradual Thickness Transitions | Replace abrupt step‑downs with linear ramps (taper angle ≤ 5°). | 20‑35 % lower thermal gradients | | Relocate Gate | Move the gate away from the high‑stress zone, ideally ≥ 3 × part thickness. | 15‑40 % drop in packing‑induced stress | | Add “Vent” or “Overflow” | Provide a low‑pressure vent near the hot spot to relieve shrinkage stress. | 10‑20 % reduction in tensile stress | moldex3d crack top
