DLP (digital light processing) uses a digital projector screen to project a single image of each layer over the entire platform at the same time. This technology converts liquid materials into solid parts, layer by layer, using (UV) light source in a process called photopolymerization.

Because the projector is a digital screen, the image of each layer is composed of square pixels, resulting in a layer that is formed from rectangular blocks that we call voxels. In summary, this technique is fast but less accurate than the stereolithography apparatus (SLA), a technique also available at Stenden University. Build volume of the EMBER is 64 x 40 x 134 mm. The open source character of the EMBER makes it accessible for 3rd party resins.

The EMBER works with PrintStudio software, used to set the layer thickness (10-100 micron), the rotation of the object, the support structure, etc. Post-treatment of the printed parts is done by alcohol wash and UV curing.
