Replace cartridge

[darylbethm]

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.

@dklgood

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:

Laser replacements after using the GF

Most laser tubes have a “10,000 hour” norm lifespan (from time of production to rated shelf/use life). Kinda like expiration date on food packages. Now from reviewing the other laser groups and postings, a better quality laser tube will be up in the 20,000 hour range. With 8,760 hours in a year, that means up to 2 years of normal usage/lifespan. With heavier usage and depending on environmental temperature controls, optimal performance lifespan will decrease (thus warranty of 12 or 18 months -…

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.
