Description
Double helix DNA model printed without supports, making it a demanding but rewarding test of both printer calibration and bridging capability. The interlocking spiral towers require precise retraction settings and consistent layer adhesion throughout the print. No mounting hardware is included — the model stands freely as a display piece. Recommended print resolution is 0.15–0.2 mm with 20% infill and a wall count of 2 for best results.
Support-free bridging challenge with visual impact
- Prints without any support structures at 100% scale
- Serves as a practical bridge and retraction test for dialing in printer settings
- Z-hop recommended if nozzle snags between towers during travel moves
- 0.15–0.2 mm layer height and 20% infill for optimal detail and strength
- Freestanding model — no assembly or mounting required
