We started 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.
Here is an article on the differences, settings, tips, and maintenance for all our build surfaces.
*Attention: It is the buyers responsibility to be sure the size selected will work on your machine. Measure your bed, do not rely on build volume. Gingerbeard.3D is not responsible for mistaken order sizes.
