In this episode, we will be using our 20watt (input 5.5 watt output) Ortur Laser Maser II (see more here: ) to etch aluminum! In the first test we used the thermal compound trick and in the second we used just a sharpie marker. The speeds for the thermal compound was 1mm/sec 100% 2 passes and the Sharpie was 1mm/sec 100% 3 passes!
