BuildTak BT10X10-3PK 3D Printing Build Surface, 10" x 10”, 254 mm x 254 mm, Square, Black (Pack of 3)

Marvellous stuff, I was a bit sceptical of all the hype for this stuff until I tried it. Very easy to apply after cutting to size and very durable. Print after print stick to this even printing in the same spot on the bed many times. No more faffing about with masking tape and glue stick, just a wipe now and then with 70% solution Rubbing alcohol and you're good to go again. I've used this first piece for over 20 prints so far and it's not showing any signs of wear at all. Some people think it's a bit expensive but it's well worth the expense to save all the hassle of prints coming off the bed part way through and the constant changing of masking tape and such.

This stuff works well for PLA, but is not so useful for other filaments. I managed to ruin one sheet by wiping it with acetone! Don't try this at home!! Isopropyl alcohol is the stuff to use to keep it clean.PETG sticks a bit too well and can be difficult to remove afterwards. Another sheet was ruined this way, as a tear appeared as I removed a part.Recently, I've been using the bare glass at 80°C with PETG. If the glass is clean it works brilliantly and 'lets go' when the glass cools down. The other benefit is the surface printed on the glass is a high-gloss finish.

Works fine in micro3d printer if you use PLA (ABS wrecks it)

Great. I will stick with it.
