#1

In DLP printing, a build platform is lowered into a resin-filled tank. The build platform moves into the tank until a gap of a defined height forms between the build platform and the tank bottom. This distance corresponds to the layer thickness with which the components are manufactured.

#2

After the picker is lowered into the resin tank, an industrial UV projector projects a cross-section of the component to be built through the transparent tank floor onto the resin. The UV light image energizes the resin, causing it to harden where the light hits it.

#3

This creates a layer of the component. The build platform moves up slightly, creating a defined gap between the tank floor and the recently produced layer. In an iterative process, the UV projectors produce a component with the highest level of detail, layer by layer.
