Wood Cutting Performance Detail
The results show that the iCube Ultra can cut through 3mm plywood effectively at around 400 mm/min at full power. Lower speeds improve consistency, especially for thicker materials.
Thanks to its fine laser spot, engraving quality remains sharp even at higher speeds, making it suitable for detailed artwork and precision designs.
---Metal Engraving Test: Infrared Laser in Action
Switching to the infrared module transforms the machine into a capable metal engraver.
