LulzBot TAZ PEI Sheet

Using PEI sheets on Taz4 and a Taz5. Overall a great print surface (nothing better that I know of) but two warnings.1. If you print with TPU put down a film using a UHU glue stick or the two materials create a permanent bond and you'll be replacing the PEI sheet.2. When printing with PETG make sure that you have a decent amount of Z space between the nozzle and the bed (equivalent to about two sheet of printer paper). If the first layer of the PETG goes down "too hard" you stand a good chance of creating an almost permanent bond and thereby increase the odds of tearing or gouging the PEI sheet in trying to remove the PETG. Replacing the PEI sheet is no fun (I speak from experience.) Getting the old sheets glue off of the glass plate is quite the work out. Here's the instructions for the Lulzbot Mini (same process only you'll be working a much larger surface area)

I like using the Lulzbot PEI sheets since they are thicker and apply a lot easier. Lasts quite a while for me. When adhesion starts to get poor it is very easy to resolve by lightly sanding the sheet with a wet piece of 2500grit sandpaper

works fine , but nor easy to replace , some bublse coms after replasment , take care with your orginal

Forget the green sheets and abs slurry. If you haven't converted over, do yourself a favor and do it now. You'll love it.

its a PEI sheer that fits a taz printer. Honestly better than the one that shipped with the unit because i could put it on correctly without bubbles.

This stuff is awesome! There is enough to cover two Flashforge Creator Pro beds.

perfect replacement part

After trying another PEI sheet (because this one wasn't available yet), I put one of these on my TAZ 4 bed (completing my upgrade to a TAZ 5), and WOW! I don't use brims anymore, and most things stick on the first try! My ABS prints don't curl up on the edges, and if I let them cool all the way, they pop right off the bed. PLA is great, too!I took my time installing the sheet, and minimized bubbles as much as possible. Do make sure you have some IPA (isopropyl alcohol) around, as you'll want to use it to clean the PEI from time to time. I use some 70% IPA, though I think 30% would work just fine.
