General Information

Laser cutter/engraver is a computer-controlled device. The process is using a powerful laser to cut and/or engrave items from flat sheet. The Laser cutter works by directing a high powered laser beam very precisely at the chosen material to either etc, mark or cut right through. When cutting, the laser beam burns away at the material leaving the cutout shape that you have specified in your vector file. The cutting beam is very thin and precise resulting in incredibly detailed and accurate cuts. By reducing the beam power where mark the surface of the material, this is known as etching or engraving and can give some stunning effects on materials.

Eligible Users

The service is available for current HKU staff and students by appointment.
