The direction the buildplate moves. Most printers move the build plate in the Y-axis direction. This is a simpler design, but gives problems at greater build height, because the inertia of the mass of the buildplate + 3D print impact the quality of the layers, requiring you to limit the speed. Other printers move in the Z-axis, allowing you to print faster without trading quality of the layer build-up.
