SLA Printers: A Journey Through the Fundamentals of Stereolithography and Resin 3D Printing Technology

In this article, we explore the essential fundamentals of SLA printers, from groundbreaking stereolithography to innovative resin 3D printing and the underlying principles of SLA technology.

1. Stereolithography:

The origin of precision

Stereolithography, also known as SLA, forms the foundation of most SLA printers. Objects are built up layer by layer by curing liquid photopolymer resin with UV light. This technology enables precise manufacturing of highly complex structures.

2. Resin 3D printing:

The key to versatility

Resin 3D printing, a subcategory of stereolithography, is characterized by the use of special resins. These react to UV light and allow objects to be created layer by layer with impressive levels of detail. The versatility of the available resins makes this approach attractive for various applications.

3. Principles of SLA technology:

Key components at a glance

The basic principles of SLA technology include the use of light-sensitive resins that harden using UV light. High-precision mirrors and galvanometers play a central role by controlling the light beams and thus ensuring the precise curing of the resin layers.


SLA printers are the result of a fascinating fusion of stereolithography, resin 3D printing and the underlying principles of this innovative technology. The precise production of highly detailed objects and the versatility in material selection make SLA printers an indispensable component in the world of 3D printing. Explore the basics with us and immerse yourself in the future of precise and efficient manufacturing technologies.
