Abstract: A metal 3-D printer includes a powder layer formation device having a blade for planarizing metal powder, a table driving device lowering a table by a predetermined lowering distance in anticipation of a formation of a powder layer, a laser irradiating device irradiating a laser beam at the powder layer to form a sintered layer having a predetermined upper surface region, a numerical control apparatus controlling the powder layer formation device, the table driving device, the laser irradiating device and a machining apparatus. When the blade collides with an obstacle formed on an upper most sintered layer, an end mill is lowered according to a predetermined lowering distance such that a lower end of the end mill is lower than an upper surface of the powder layer, and moves the end mill across a predetermined upper surface region of the uppermost sintered layer to remove the obstacle.
