The device comes fully assembled and only needs to be leveled. Advantages of the Anycubic Photon S 3D printer: 2.8-inch color-sensitive touchscreen for real-time preview of the print status. Integrated offline printing. Rapid Slicer - Photon S Workshop. Enhanced UV module for stable signal transmission, efficient use of resin energy, and amazing printing and curing results. Dual Z-axis linear rail for greater stability. 2K LCD masking screen 2560 x 1440 (2K) HD masking LCD delivers very fine printing details down to a few micrometers. With the "S" version of the Anycubic Photon, several changes and improvements were made that distinguish the two models. The Anycubic Photon S features a dual Z-linear guide, reducing artifacts in print quality by making the mechanics even more stable and robust. Additionally, the newer version includes a revised matrix UV light source and activated carbon filtration for unpleasant fumes and odors.
