Getting that first layer to stick is essential, especially with large objects. Without a solid foundation, the rest of your print may deform or even fail to extrude properly, but it can be difficult to keep your print surface sufficiently clean. To further complicate matters, reducing your initial extruder offset can make it really hard to detach the final product from the bed or squash lower layers. Luckily, this polyimide-foil tape offers the perfect surface for creating consistent prints that are easier to handle.
