The additive manufacturing head includes: a head body into which a laser beam is introduced; and a laser tool detachably mounted on the head body to emit the laser beam and define a laser-beam-irradiated region on the workpiece. The manufacturing machine further includes: a laser tool stocker storing a plurality of laser tools; and a laser tool exchanger for exchanging laser tools between the head body and the laser tool stocker. A high productivity of additive manufacturing is achieved by using the above features configured in this way. ## Claims ### Claim 1 A manufacturing machine capable of subtractive manufacturing and additive manufacturing for a workpiece, the manufacturing machine comprising: a tool holder disposed movably in a machining area and configured to hold a tool to be used for subtractive manufacturing from a workpiece;
