Replace cartridge

How often do you have to replace the cartridge on the glowforge?

Welcome to the forum. By cartridge I am assuming you mean the laser tube. I think I read somewhere that the tube is expected to last about 2 years.

I believe that’s at least 2 years for “average use.” Since the tubes are only now hitting the 2-year mark in general use, that data is really just coming into existence right now.

I’ve never seen a definition of “average use.” (I would love to!) I’ve had my machine for 2 years now and I see no degradation in my results.


This is not the official answer, just one from another post - but it gives a nice overview:

Dan has said 10k, he’s also said 2k; the official answer is 2 years. YMMV


Thanks for the help everyone!

@darylbethm what @dklgood mentioned is correct! The Glowforge tube is custom made - it’s bigger than most desktop units (850mm) and has some modifications for longer lifetime and smaller spot size. It’s rated for 2 years.
