We start with our original high chromium spring steel Flexi Plates and pre-install our Wham Bam PEX Build Surface made 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. Works perfectly with your Wham Bam magnetic base, not included.
