PEX replacement sheet for your Flexbile Build Plate System or if you want to build a spare plate. 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 0.4mm thick and pre-backed with 3M adhesive so it takes seconds to install. *Please confirm bed size on your actual machine prior to ordering. Gingerbeard.3D is not responsible for mistaken sizes ordered. See the Wham Bam sizing guide.
