Digital Light Processing Moving Light, DLP Moving Light

Additive manufacturing method in which a moving DLP projector and mirror is used to solidify a liquid polymer layer by layer.

The process

Objects are built in a container filled with liquid photopolymer, which is a plastic which reacts to light. An adjustable building platform is initially placed in its highest position, submerged in a thin layer of liquid photopolymer. A procector cobined wiht an angled mirror projects a series of projectins across the entire platform to solidify the complete cross section.

The platform is lowered so that the previous layer is now covered by a new, thin layer of liquid. The DLP projector solidifies a new layer which sticks to the previous layer.

Support structures can be created if needed, if the liquid cannot support the weight of the overhanging parts of the component.

The process is repeated until the object is completed and the finished part is usually cleaned by ultrasound and alcohol.

Support structures are removed and the object is cured in a UV oven.

Non solidified liquid can be recycled to produce new items.

DLP Moving Light can be used to make larger, high resolution parts than fixed DLP printers.
