DLP Technology: On the other hand, DLP technology uses a digital projector screen to flash a single image of each layer across the entire platform at once. Each layer of the 3D model is displayed as square pixels, meaning that the print is comprised of voxels. Flashforge Hunter is using DLP Technology. LCD 3D Printing: As for LCD 3D printing, the process is nearly identical to DLP in that it utilizes projected light to solidify resin layer-by-layer until a 3D model is built. The main difference is that LCD 3D printers use a bank of UV LEDs to project light through a mask of the layer on an LCD panel. In contrast, DLP 3D printers utilize an array of micro-mirrors (each mirror corresponding to a pixel) to either project light, or not, thus creating a mask. Itech 3D Printers uses the LCD technology.
