LASER4DIY - Open-Source Laser Structuring for Making PCBs

Project description

Laser4DIY is a open-hardware machine for producing electronics boards by ablating copper with the use of a laser. It consists of several parts: a micro-chip based DPSS laser source, driver electronics for the pump laser diode, a cooling system including a 4-channel TEC-Controller, a low-profile, motorized XY table and a safety enclosure.
