What is the life expectancy of the Kossel?
Much like your car, the number of miles, or the number of prints that you can get out of it is entirely up to how well you can maintain it.

A 3D Printer is a machine, and a machine needs general maintenance; if you see something starting to break - or get worn out - or anything abnormal, fix it.

I am sure that if you had something like a MakerBot, it would require less maintenance then a fully home built machine, but if you are building it from scratch, I am sure you don't mind.

I am still rocking a 3 year old home built MendalMax, and have both made some improvements, and had to make some repairs along the way - but it is still in damn good condition.

For a $600 investment, I can say you will get a few years out of it if you take proper care of it. By the time the end of its life comes (5+ years), I am sure there will be much better printers available for cheaper, and you will never look back :)
