I'm surprised the laser tube is $1000. It's not much different than a light bulb. Sure it is different, but not by that many zeros.
- driverdan 7y agoIt is different by that many zeros. They require much tighter tolerances and higher quality materials. They're also not mass produced. You can get cheaper laser tubes but there is a difference between them.
- mdorazio 7y agoThat’s debatable. I had a laser cutter for a couple years and used cheap tubes off eBay with zero issues. Cutting power was probably less per watt than with an expensive tube and lifetime was lower, but at 1/4 the price it doesn’t really matter.
