What is DLP 3D Printing and How Does it Work?

The Process

DLP (Digital Light Processing) 3D printing is a process in which a DLP projector light source cures photosensitive material/resin. At the heart of the DLP process is a DLP chip; a precision device made up of millions of microscopic mirrors which can be individually controlled to produce clear and crisp images.

domeless 3d printing with dlp 3d printing technology

CDLM Domeless 3D Printing

To print continuously (without peeling) requires flowing oxygen through a permeable film just above the print bed to create a “dead zone”. Within this “dead zone,” the polymerization process is inhibited ensuring the
layer being printed adheres to the layer above and not the printing bed film. This “dead zone” is what enables continuous printing, where the build plate can continually move in the Z-axis, leading to faster, more
reliable prints.

On competitor “dead zone” printers, by comparison, air pressure from the flowing oxygen causes the film to dome up. Printing parts on that domed surface greatly impacts resolution along the Z-axis, as well as the
ability to print flat parts on the build plate.

ETEC’s CLDM technology uses over 200 thousand pillars to hold the film perfectly flat, resulting in significantly better Z‐axis resolution and allowing for the printing of flat parts straight to the bed with no supports.

Powered by Oxygen

Oxygen (O2) inhibits polymerization and that particular small area, where the oxygen and the photopolymer blend on the surface, is called the dead zone. This translates into a thin layer of material that doesn’t cure or harden, even when directly exposed to light. Therefore, in order to successfully build continuously, the projector light needs to be strong enough to accurately and rapidly transfer through the dead zone and cure the resin. This dead zone proved to be beneficial because it can be used as a no-stick zone, meaning that the parts no longer have to be peeled from the material tray in between exposure layers. This approach allowed for 3D printing in free space.

Despite the discovery of the dead zone’s benefits, over the years, continuous 3D printing saw another challenge that needed to be overcome in order NOT to compromise speed, part accuracy, or isotropic properties. To continuously 3D print in free space, the usual practice was to deliberately insert oxygen into the process to create a dead zone by adding the O2 below a thin rectangular piece of oxygen-permeable film that was covering the entire build area. Thus, the film was allowing just enough oxygen to penetrate to create a dead zone on which to free-print.
