We have developed the Wham Bam PEX Build Surface from a specially formulated polymer with a higher melt point than PEI that attracts most any filament without damaging the sheet. Prints easily pop off once cooled and flexed. Our PEX build surface is 0.35mm thick and pre-backed with 3M adhesive so it takes seconds to install.

Best build surface for the Bambu Lab X1C wasted my money on others.


Works perfectly as expected

It’s not the easiest thing to apply. Just take your time and you’ll do better than I did

My nozzle though.

The nozzle on my Bambu labs cut up into the sheet. My nozzle ettched into it as it was in print mode. Scratches render the sheet useless. My sheet lasted about a month and is an aid to improving layer adhesion and first print layer.

Hi Johnny,
We are sorry to see you are having issues with your nozzle that is damaging all your different Flexi Plates in the same way. Please reach out to our technical support team at so they can help you adjust your settings and get back up and printing!
