3D printers, specifically SLA printers, use galvanometers to control the movement of mirrors that direct the UV laser beam during printing. Through the use of galvanometers, the laser beam is tracked onto the surface of the photosensitive resin layer by layer as the cross-sectional pattern of the 3D object is traced.

It works by converting electrical signals into angular motion. There are usually two galvanometers in an SLA printer, one for the X-axis and one for the Y-axis. In order for the laser beam to accurately trace an object’s pattern, each galvanometer receives electrical signals and moves its mirror in coordination with the laser beam’s position.

Having high-quality galvanometers ensures fast and precise mirror movements, resulting in high-resolution prints with smooth surfaces and fine details.
