Reddit reviews PEI (Polyetherimide) Sheet, Opaque Off-White, Standard Tolerance, ASTM D5205 PEI0113

You need to get yourself some PEI

GOD PEI WHEN WILL PEOPLE REALIZE THAT THEY DONT NEED HAIRSPRAY OR TAPE OR GLASS OR VOODOO MAGIC BECAUSE PEI WORKS BETTER THAN ALL OF THOSE

FUCKING PEI EVERYONE

EDIT: PEI FFS

I get the raw PEI because I have some high temperature tape available at the makerspace. That one is probably fine, too.

Congrats on your decision! Hope you enjoy it as much as I do.

As far as the auto bed leveling kit, it's brand spankin new and it's the first time I'm seeing it. There were rumors on here of MTW releasing that. Manual bed leveling with the clips that come with the kit were a huge pain in the ass; there was too much play and you need a hex key to level it. I printed Easy bed levelers which are light years better. Manual bed leveling now takes just a quick couple minutes, which I only do after a handful of prints. While you're at it consider these for your printer, too (not necessary but will make your life a lot easier once you start printing):

• Blower fan duct - you'll need to spend a couple dollars on a blower fan, but the shroud keeps air flow directed at your print rather than blowing at, and cooling, the heating block.
  
• PEI sheet for the bed - no painter's tape, no glue, no hairspray, no abs slurry. Prints just stick to it without any prep work. Just keep it clean with isopropyl alcohol.

I've had good success with .03inch thickness (0.762mm)

That's a bit thicker than you would tend to find, but it has the benefit that you can use high grit sandpaper to resurface it many many times. I'm about 200 prints in on my first sheet, and I suspect it'll outlast the printer if I don't break the mirror tile it's on. (the sizes are awkward on this listing unless you have a 12x12 build surface like I use)

Cut it out w/notches for the bed leveling screws, hold it on w/binder clips (or 3M adhesive sheets). Holds like crazy when warm, releases easy when cool. Can even take it off and bend it to pop off harder/fragile prints.

This is the sheet I used for my Taz (I used .06in.) and can attest it is most definately solid PEI and quite durable. It makes very shiny parts.

Cut the sheet to the size of the bed. Put the glue on the sheet with the old windex+credit card deal. Put the sheet on the bed the same way.

Adjust your Z height to account for the thickness difference.

Never ever worry about bed adhesion again, ever.

I actually use a sheet of PEI that is 0.03 inches thick and stuck to my print bed with double sided tape. It gets sticky when it heats up and releases the parts when it cools. The best part is that the only thing I have to do between prints is wipe it off with isopropyl alcohol.

Just a word on PEI: All Lulzbot printers now come with a PEI sheet pre-installed, and it works wonderfully for several months until bubbles form and soon you have to replace it. But if that's what you like, cool.

Do note of course that you can buy large sheets of plain PEI on Amazon, along with adhesive sheets, allowing you to install PEI on any printer. If you're lazy, Gizmodorks also sells pre-cut PEI sheets with adhesive already attached.

But also be warned: if the LB autoleveling process somehow screws up because of poor electrical contact and doesn't realize it, your PEI gets messed up real quick, and replacing PEI, as you may know, is quite the pita.

GREAT material for printing adhesion. NO glue, no hairspray, just clean it every once in a while with alcohol

pick up a 12" x 12" x 0.03" sheet and never look back.

For the 1mm PEI sheets I have (roughly 12x12") I paid something like $15 each via Amazon (link https://www.amazon.com/Polyetherimide-Off-White-Standard-Tolerance-PEI0113/dp/B00CPRDDLY). The thicker sheets are far more expensive but there's absolutely no point in getting thicker sheets.

The prints pop right off once it has cooled down a little. I'd estimate once it gets down under 70°C it's simple to remove. I'm not all that patient and want to get at things as soon as they are done. It's not fun to try and remove prints while the bed is hot. I'm rarely successful at it. Also there's no need to worry about messing up the PEI if you decide to try and remove a print while it is hot. The PEI is still super hard even when 100°C.

I saw this solution called Wolfbite on Tested last year. Its supposed to work with PETG too to prevent warping, but I haven't personally used it.

You could also try a sheet of PEI over your glass bed.

>The price is decent.

Not really, make sure you're thinking of the right thickness. The 0.03" sheet most people use from Amazon is $30 for 12x24".

CS Hyde's price is $40 for 12x12", and only 0.02" thick too. You're basically paying 5x as much as the Amazon price. Sure it already comes adhesive backed, but is that really worth it?

Just to clarify your clarification, something like this?
