These CPFA Release Films are genuine replacement parts for the GK3 Pro 3D printer from Uniformation. The films are 320mm x 20mm x 0.25mm and have undergone a special treatment that gives them excellent strength and durability. Due to the elasticity, it is easier for the CPFA film to release from the cured layer, which ensures better print quality and an increased chance of successful 3D prints. This package contains 3 pieces.
