How does SLA / DLP 3D printing work?

SLA (stereolithography) is the main additive manufacturing process, collectively known as 3D printing.

Stereolithography (SLA) or digital light processing (DLP) is a technology that uses a UV-sensitive liquid resin. The ray of an ultraviolet laser or ultraviolet light from a projector selectively hardens the material corresponding to the cross-section of the product, creating a three-dimensional part beneath it.

The technology requires preliminary construction of supporting structures in the model – supports, which are necessary for printing protrusions, cavities. Supports are manually removed after printing is complete.

SLA / DLP capabilities.

The undoubted advantage of SLA / DLP printing technologies is the high detail of the prototype, as well as its perfectly smooth surface. In addition, there is a wide range of materials available, allowing parts with different characteristics to be created: for example, to reflect the characteristics of engineering plastics, burnout polymers for investment models, or rubber-like materials for experimental purposes.


SLA / DLP is one of the most affordable and cost effective rapid prototyping technologies. It is significantly cheaper and does not require any complex tools, as in plastic injection molding.

Mass production.

Our SLA / DLP printing service enables the production of parts and prototypes from a wide range of materials, but specializing in small items with high detail. Prototypes can be easily used for testing or as main prototypes in serial production and replication by making casting molds.
