An LCD (Liquid Crystal Display) is an essential component of a typical SLA (Stereolithography) 3D printer. The LCD acts as a mask to selectively allow UV light to pass through and cure the resin in the desired pattern.
When a UV light source is directed through the LCD, it selectively cures the resin in a pattern, which gradually builds up to create the desired 3D object. The resolution and accuracy of the final print depend on the pixel size and density of the LCD.
Therefore, when choosing an LCD for your SLA 3D printer, it's essential to consider the pixel size, pixel density, and resolution. Additionally, you must ensure that the LCD is compatible with the light source used in your printer.
Some popular LCDs used in SLA 3D printers include Sharp LS055R1SX04 and Tianma TM070RDH10, both of which have a pixel resolution of 1440 x 2560 and are compatible with a wide range of SLA 3D printers.
