Welcome to the forum, @himehran2000! Here is one of many discussions about reliability that took place on the forums. The motors, the cameras and the controller boards should be no problem of reliability since that is a very mature market. The CO2 laser has a limited life span, but sourcing the Glowforge laser to be reliable was an important part of the project. The power supply was a big concern as to reliability and ability to power all the systems correctly flawlessly. Evidently a huge issue. Now that there is a public beta, the question of reliability is getting answered in the real world. I would imagine over the next few months that testing the systems out will give some great answers to your question. Everything I read here is that Glowforge wants to meet and exceed normal expectations of reliability for this type of consumer electronic.
