So today I tried my hand at laser engraving on ceramic tiles bought at Bunnings Warehouse, and I wasn’t expecting much with the diode laser, however it actually turned our quite well. It was a slow process though as it took a couple of hours to complete with the 20 watt module at 100% power and speed 500 (mm/sec) to ensure it actually etched it. However the end result looks as we say PDG… Pretty Darn Good.
