Synonyms:
Galvo
An electro-mechanical device that converts an electrical signal into a magnetic field that in turn moves a set of mirrors. This allows for very fast and precise pointing of the mirrors.
In manufacturing and especially additive manufacturing, a mirror galvanometer is used to point a laser beam onto the build service. This produces the scanning pattern used in vat photopolymerization and powder bed fusion processes that use a laser.
Most systems use two mirrors, one for the x-axis and one for the y-axis. Some systems will use multiple laser and mirror galvanometers to scan in parallel.
The speed and accuracy of the mirror galvanometer determine the speed and accuracy of the machine that uses them.
