Digital Light Processing DLP 3D Printing Process

Digital Light Processing was first developed in 1987 by Larry Hornbeck — but not for 3D printing. The tech was developed for projectors and for cinema usage well before it’s potential benefits in 3D printing were discovered. Now, over 30 years later, DLP

DLP printers excel at creating high-detail pieces and surfaces that exceed other 3D-printed techniques and are highly accurate. This innovative process constructs solid objects layer by layer, with the projector emitting UV light to harden the resin preci

Among these techniques, DLP 3D printing, which involves projecting 2D patterns of light onto a vat of photopolymer resin layer-by-layer using a digital projector, offers indispensable...

DLP 3D printing uses a digital light projector to project an entire layer of the object onto the surface of a vat, solidifying the liquid photopolymer resin according to the shape of the object.

Despite the advancements in projection-based digital light processing (DLP) methods, achieving a balance between high resolution, extensive print areas, and rapid print speeds remains a challenge.

The main components of a DLP 3D printer include the digital light source (projector), the resin vat, and the build platform (where the print is created). Heaters are optional but allow for a broader range of materials, including high performance materials

DLP (digital light processing) is a 3D printing technology that makes use of a projector and a DMD (digital mirror device) to selectively cure a photopolymer one layer at a time. The DMD is an array of tiny mirrors that direct UV light at the build plate
