Why choose Digital Light Processing (DLP)?

One of the biggest strengths of Digital Light Processing (DLP), which is one of the newer 3D Printing processes, is the material chemistries of its resins that resemble production grade materials. The DLP material range addresses a wide variety of applications needs, for functional prototyping, direct production of end-use parts and molding and casting. Available materials cover a wide range of critical properties and include rubber-like, castable, heat resistant, and rigid and durable with thermoplastic-like behaviours materials.

The DLP process is particularly suited to parts with complex structures with small cross sectional areas that require good surface finish and high strength properties.

Models produced using digital light processing are manufactured with ultra fast print speeds and parts can be turned around rapidly. This makes it a very suitable process for projects which require efficient design iteration.

DLP is ideal for low volume production as production-grade parts can be manufactured without tooling at competitive prices.

Finishing options

LPE has a team of experienced in-house traditional model makers and a full spray-painting booth allowing us to offer our customers a range of finishing and painting options.


Supported surfaces are sanded to remove support structures. Other surfaces are not sanded.


Components produced using digital light processing are sanded to remove support structures and build lines and then bead blasted for an overall smooth finish.

Metal Plating

It is possible to metal coat DLP components parts in a range of different metals including chrome and nickel.

Other paint finishes

It is possible to give DLP parts a range of paint finishes including cosmetic (Pantone/RAL colour matching), matt, satin, spark or gloss.

How does DLP work?

DLP or Digital Light Processing refers to a method of printing that makes use of a projector as a light source to vat polymerise (cure or solidify) photosensitive polymers (photopolymers).

Each layer of the desired structure is projected into a vat of liquid resin from below. When one layer is solidified the build platform moves up by one layer in height and the process is repeated until the part is complete. The advantage of this method over traditional SLA is that the entire layer is cured in one go, whereas with SLA a laser beam has to draw the 2D image with a small beam which can take much longer.

As the part is drawn upside down through a clear window at the bottom of a tank there is no need for a re-coater in the DLP process. Removing the need for a recoating mechanism allows for smaller build layers and faster processing.
