How it works:
A projector flashes an entire layer of light onto the surface of the resin, curing it all at once. Each layer is formed in a single exposure using a micromirror array that defines the resolution. As shown in the diagram, the resin is cured in the XY plane, while the platform moves down along the Z axis to build the part layer by layer.
Where it’s used:
DLP is used in dentistry, audiology, and jewelry for creating detailed molds, models, and aligners. It's also common in prototyping for consumer products and electronics. Thanks to its speed and fine resolution, it's gaining traction in small-batch manufacturing, design studios, and desktop printing environments.
