My TAZ5 is currently my only 3D printer, and as such, is a major tool in the lab. I was in the middle of a build for a client, when the last print decided not to release from the PEI bed film. I had been having problems with bubbles over the past several months. In spite of trying very carefully to pry the piece off, the film failed in the center and lifted a fist-sized section free of the glass. I could have continued to print small items around the periphery of the bed, but I need that center real estate for the lager prints associated with the current job.
A friend suggested printing on bare glass, but I have experience in that particular approach. I had chipped beds multiple times, and witnessed several others do the same with that approach. So I decided that I wanted the protection of the plastic sheet.
I have a video covering the replacement of the bed here.
Now that I have the bed repaired, I am free to resume prints, but I am currently having electrical work done at Hangar -1, so I am reluctant to start another print until that work has concluded.
