my printer comes with a glass bed. i do know one or two guys that have had their bed etched or bought etched glass and they say it works better but it still depends on what your printing. it wont bond abs alone or anything like that but if you like glass and you want a little more bite then yes. i removed mine and replace it with a piece of mic6 aluminum which i glass beaded on one side. i like that much better. the heat is more even and a few coats of hairspray fills the etching and i can just keep printing and printing on the same surface.
