[Sonic Mighty 8K] Replacing the LCD

The LCD screen is an essential component in resin 3D printing. It is responsible for generating an image of each layer while an array of LED chips project light through it to cure the resin.

As the LCD screen is a consumable part, it may need to be replaced after a period of use. When the LCD screen becomes damaged or worn out, it can result in lower print quality or failed prints. Therefore, replacing the LCD screen is necessary to ensure the continued performance and accuracy of your 3D printer.
