Abstract: A laser assembly for additive manufacturing which includes a first laser beam aligned in a first direction and a first partial reflecting fixed mirror positioned aligned with the first direction which reflects a first portion of the first laser beam in a second direction and an exponentially reduced remaining second portion of the first laser beam passes through the first partial reflecting fixed mirror in the first direction. The laser beam assembly further includes a first oscillating mirror positioned aligned with the second direction of the first portion of the first laser beam wherein the first portion of the first laser beam is refracted by the first oscillating mirror in a third direction.
