Can a Thunder laser cutter thick wood? It depends, now we are going to show you laser cutting 18mm hard wood. To cut such a thick wood, you must use a 4″ laser head to get a straight cutting quality and a high pressure air compressor to reduce the burn and avoid fire. And you can only use very low speed.
You can learn more about 4” head and the high pressure air compressor from this link:
