What Is The Flexible Build System?
Are you having a difficult time getting your 3D print to stick to your printer bed? Does your print peel up during a long print and destroy your work? Are you tired of temporary fixes such as glue sticks, hair spray, and painter’s tape? Once you get your print to stick, do you have to pry, chisel, cut the perimeter, or put your bed in the freezer, just to get your print off the surface without gouging the surface or cutting yourself?
We have created the specially formulated Wham Bam PEX Polymer Build Surface which surpasses PEI in temperature resistance, performance, and material ‘stickability”. It sticks so well you would have a heck of a time getting the print off the bed without our Wham Bam Flexi Build Plate. Simply remove the Wham Bam Flexi Build Plate from the Wham Bam Flexi Magnetic Base on your 3D printer when the print is finished and flex slightly to pop your print right off! See our demo video below.
