This tiny amount of oxygen right at the boundary prevents the solidified resin from sticking to the bottom, allowing the Z axis to be moved up continuously, speeding up printing significantly.

As the printer pulls up the forming object, suction feeds more low-oxygen resin toward the bottom. Drastically speeding up the curing process also makes for smoother 3D prints.

While filament-based 3D printers are extremely capable and slicing software is only getting better, resin-based printers are able to produce prints of nearly unparalleled quality.
