A refurbished X1-4K 5.5" mono screen printer.  3-month warranty.
Printer Specifications:

    • 4K MONO (5.5 inch) LCD masking screen. 2160*3840 (4K) HD masking LCD allows for amazing print detail and much faster printing speed.  It typically only needs 2.5 to 3 seconds for normal exposure time, compared to color screen which needs 8 to 10 seconds.  Pixel size is 31.5 microns.
    • The mono screen can last several thousands hours of normal use.
    • Parallel Matrix UV light source -- This is the most advanced light source, providing more print detail for dental and jewelry applications where finer details are beneficial as well as a more even distribution of the light across the entire build area.
    • 3.5-inch Color TFT Touchscreen.  
    • Excellent Z-axis stability. 
    • Pre-installed nFEP film to allow easier detachment during printing (you can still use standard FEP films with this printer if you prefer).
    • Sanded build platform surface made of soft aluminum for better adhesion and easier print removal.
    • Anti-Aliasing supported and enabled in installed firmware.
    • Wide selection of supported resins - you can use any 405nm wavelength 3D printing resins.
    • 120.96mm (L) *68.04mm (W) *155mm (H) build volume
    • Ethernet port installed for network printing.

- 5.5" 4K Mono Screen - This screen has a resolution of 2160*3840 (4K) and a pixel size of 31.5um making it the best precision and lowest pixel size currently available to LCD resin printing. 

The screen has a 120.96mm x 68.04mm on XY printing area.

- Mono screen lasts much longer than color screen and only needs 2-3 seconds of exposure time for each layer.

- Parallel Matrix UV Light Source - This UV light provides more accuracy and allows for the capturing of finer details.


- Non-FEP Film for Resin Vat - Our nFEP film has a lower release force than standard FEP films, decreasing your likelihood of print failures caused by layers not releasing from the film. 

- Ultra-Precise Fixed Build Platform - EPAX uses a stable 4-point mount. Your build plate is leveled at the factory.

- Better Chassis Design - Our printers have all-steel chassis with minimal windows for durability and minimal UV light contamination.

- Precise Z Homing - All printers are individually calibrated and leveled at the factory so you can begin printing out of the box.
