A beam steering system in which the printhead follows a printpath along a curve, such as printing of a heat exchanger thin walls, typically undergoes errors due to varying beam angles, beam focus and beam speed. The present disclosure provides solutions to error reduction and increases reliability for printing rings and hollow objects related to 3D printing. Accordingly, a wall described by a curve function, may be fabricated using a printhead, which is moved in a print path that keeps the print lines orthogonal to the print path and tangent to the inner center line curve between the outer wall and the inner wall.
