The process starts with a vat of liquid photopolymer resin. A digital light projector, often an LED or a high-resolution DLP projector, projects a layer of the object’s cross-section onto the resin. The light causes the resin to harden in the areas exposed to it. The build platform then lowers slightly, and a new layer of resin is spread over the previous layer. This process is repeated layer by layer until the object is fully formed. DLP is known for its high resolution and speed, making it ideal for producing detailed and accurate parts, especially in industries like jewelry, dental, and prototyping.
