Elegoo 【Pre-Owned】Mars 4 DLP - Open-Box

ELEGOO MARS 4 DLP 3D printer adopts TI (Texas Instruments) DLP technology to project the 405 nm beam directly and concentrated onto the bottom of the resin tank with up to 95% light uniformity. Tempered glass replaces traditional LCD screens with up to 95% light transmittance, effectively reducing light diffusion and stray light interference. Meanwhile, the full-gray antialiasing algorithm greatly reduces the jagged edges, making the model surface smoother and more delicate. 【2W+ Hours Lifespan 】 The service life of the DLP projector is as long as 20,000+ hours, 10 times longer than the 2,000 hours lifespan of an LCD screen, which means you will save a lot of maintenance costs for replacing your LCD printer's screen. 【 Low Power & Ultra-quiet Printing】12W ultra-low operating power is energy-saving and eco-friendly, with about 1/7 energy consumption of LCD printers. Since lower power consumption generates less heat, there is no need for a cooling fan to dissipate heat, reducing print noise below 48 dB. 【 More Stable Structure 】 The Z-axis linear rail is thickened from 15 mm to 20 mm, which effectively reduces the vibration amplitude during Z-axis movement and the layer pattern of printed models for better final print results. Sandblasted surface build plate with strong adhesion to improve the printing success rate. 【 Smart Voxeldance Tango Slicer 】 Three printing modes are optional: static mode and dynamic mode (including smooth and high-speed mode). In dynamic mode, the slicing software will dynamically adjust the printing speed by the cross-sectional size of the printed model to reduce the impact of the release force, thereby improving the printing efficiency. In addition, ELEGOO self-developed a new open-source GOO slicing format, which is compatible with multiple slicing software without restriction. 【 Purified Printing Environment 】 The USB-powered air purifier with built-in activated carbon can absorb and filter resin odor to create a refreshing printing environment. Or you can choose the upcoming ELEGOO's first large air purifier (247*210*410 mm) designed specifically for the photocuring field, which can remove formaldehyde and up to 80% of VOC.
