How Do DLP 3D Printers Work?

DLP 3D printing uses a digital light projector to cure liquid resin layer by layer with high precision. Each layer is exposed and solidified in one flash, making the process fast, accurate, and ideal for fine-detail parts.

Digital Model Preparation

The process starts with a 3D model, which is sliced into thin layers using specialized software. These slices guide how each layer will be projected and cured.

Light Projection

A digital light projector flashes each sliced layer onto the resin surface, curing the entire layer at once with high precision.

Layer-by-Layer Curing

The build platform gradually moves up (or down), allowing new resin to flow in. Each new layer is cured on top of the previous one, building the part layer by layer.

Post-Processing

After printing, the part is cleaned of excess resin and may be post-cured under UV light to enhance strength and stability.
