LCD is an essential component of resin-based 3D printers. The LCD screen is responsible for displaying the layers of the 3D model that will be printed. The light from the LCD screen passes through a bottom layer of a resin vat, curing the resin in a precise pattern that matches the 3D model's shape.
To ensure that the Shuffle’s LCD screen is working correctly, you can perform an LCD test. This test checks if the lighting and masking functions of the printer are working correctly.
There are three modes to choose from when testing your LCD screen.
Mode 1: Light up the entire LCD screen
Mode 2: Blacken the LCD screen
Mode 3: Display the LCD grid
By testing your LCD screen in these three modes, you can check all the different features of the screen and make sure it's working properly.
DO NOT look directly at the UV light to prevent eye discomfort.
Mode 1: LIGHT UP THE ENTIRE LCD SCREEN
- On the touch panel, click on LCD TEST > LIGHT UP ENTIRE LCD SCREEN
- The LCD will illuminate the entire screen and allow you to check for any dark areas or black spots to ensure the screen is fully functional
Mode 2: BLACKENED LCD SCREEN
- On the touch panel, click on LCD TEST > BLACKENED LCD SCREEN
- The mode will cover the entire screen with darkness, allowing you to identify any light spots or backlight bleeding, and verify that the screen can display true blacks
MODE 3: LCD GRID
- On the touch panel, click on LCD TEST > LCD GRID
- This test will display a grid on the LCD screen, which you can use to verify that the UV lights are working correctly
Performing a Dry Print
If you're experiencing issues with such as flickering or glitches, a dry print can be a helpful troubleshooting tool. A dry print is a test print that you run without placing the resin vat and building plate. This allows you to check whether the LCD is flickering or functioning correctly.
- Remove the resin vat and building plate from the printer
- Save a sliced file onto a USB drive and then plug it into the USB port on your printer
- Click on the file from touch panel to start the print
- Check the LCD screen to see if the image displayed on it matches the one on the touch panel
Performing a dry print can help you to identify any issues with the LCD and ensure that it is functioning correctly.
If you notice any discrepancies between the image on the touch panel and the LCD screen, contact Phrozen support or your authorized reseller for assistance.
