Fast and StableAnycubic photon mono 4 ultra adopts the new generation ACF film and Intelligent Release Algorithm, accelerating the maximum fast print speed to 120mm/h. ACF film minimises frosted texture to increase light penetration for a much smoother release process to maintain the print accuracy 10K High Precision Photon Mono 4 Ultra boasts an impressive 105% increase in print precision compared to Mono 2. A 7-inch 10K screen with a resolution of 9024x5120, each pixel measures a mere 17x17m on the XY axes. Using 8mm diameter T-type screw rod and precision guide rails, this enhanced capability allows for creating models with exceptional detail and dynamic richness. Advanced COB Light SourceThe COB light source system combined with Fresnel lenses can reach the light angle within 3° ,ensuring no stray light interference on the monochrome.
