Prusa PEI sheet alternatives.
I have used Buildtak’s PEI sheets on their flexplates for over a year. I have one for PETG and one for PLA. Both sheets are still in use today. I print something every day, sometimes just a few hours sometimes for 50+ hours. I damaged Prusas PEI smooth sheet the second day I used it, and after a month I had several bits of it coming of it. There is no comparison IMHO.
Most people say PETG adheres “too good” on the smooth sheet, I’d like to say that the quality of the smooth sheet is bad. I really do like the textured one though.
I've been using the black Buildtak sheets on my cobbled together large printer for years. I think I got the 3 pack 4 years ago and I still have one unused sheet.
When I got the Prusa I got a FYSETC 3D steel sheet that came with one PEI sheet, also got a spare PEI sheet made by Gizmo Dorks. The steel sheet seems good quality with similar printing to the Prusa, took some time to apply the PEI and trim the edges but when done it worked fine for the few test prints I did. Haven't tried the Gizmo Dorks PEI sheet yet.
I only applied PEI to one side of the steel sheet and covered the other with painters tape. TPU sticks so darn strong to everything it's nice to have a disposable surface for that. Also any tape that bonds to the TPU print and tears off the bed can be removed from the print with hot water and some scrubbing.
Ok-thanks. I will check these out!
