Abstract
A method for 3D printing an object with at least one wall () having a first surface and a second, opposite surface, wherein the first surface is intended to serve as an optical functional surface, wherein the wall is formed by printing one track () on top of another track (). An orientation of the object during printing is selected such that the wall has a tangent (or tangent surface) non-parallel to the z-axis, such that the first surface faces away from the x-y plane and the second surface faces the x-y plane. According to the invention, the 3D object is thus oriented during printing such that the first surface, intended to be used as an optical functional surface, faces away from the x-y plane, i.e. typically away from the support or platform on which the 3D object is printed upon. By ensuring this orientation during printing, the first surface becomes smoother than the second, opposite surface of the wall.
