Cool. I will order a sheet then to learn with. I bet I can take it to work and use our router to trim it down to the right size, we cut acrylic all the time. I will probably get a little thicker sheet tho to make cutting easier.

Yep, Buildtak is pretty darn good. If I didn't own 5 sheets of it, I might try this PEI stuff...

It amazing how much crap you don't have to deal with when your print sticks no matter what. I am 300 prints or so into my current sheet of buildtak on the i3v and more then that on the other 2 3d printers I have. Wonder how much time i have save by not spraying and not cleaning the surface over and over again.

Both of these material sheets (PEI and Buildtak) are pretty intriguing. Especially since on the buildtak website an 8x8" sheet is only 10 dollars and because of bstags testamonial above.

Is the buildtak spongy? Would ABL accuracy be affected if it is? So far I've been a stickler for hardware store glass but I may make the switch!

I wonder, does the Buildtak go straight on the bed heater, or on the glass?

Not "spongy" but not rigid either... trying to think how I'd describe it... maybe like a hard rubber...

I put mine on glass. That way I can pull one print off, drop another BuildTak covered glass on, and start printing right away while the already finished print is still cooling off...

Yeah put it on your flat surface what ever it may be. In my case its a aluminum bed. To describe the surface would be best as really fine sandpaper thats been filled in..

As I currently have only one piece of borosilicate, I think I'll get only one sheet of Buildtak to try. If I like it, and get more borosilicate, I'll get more later.

I am totally impressed with the PEI sheet. I have mine attached with the high temp 3m double sided adhesive tape. No issues with prints sticking, every few prints or so, I also give it a light sanding with 2,000 grit sandpaper. I have been printing mine at 235 hotend, and 90 for the bed. If they get a 10x10 buildtak, I might have to try that sometime. correct me if I am wrong but they don't make that size yet.
