The product is divided into two parts: A (upper)+B(lower)
Part A: The top is a matte surface, and the back is magnetic (the interaction with the front of Part B plays an attractive role)
Part B: The top is magnetic (with the adsorption under the A part), the back is the adhesive (posted on the printer platform, which plays a fixed role)
Simply stick the bottom plate onto your build plate and start printing, peel up the top plate with finished prints, then peel off the top plate from the prints. Take the top plate back into place for next round of printing.
