Kind Code:
A
Abstract:
To provide an improved method of controlling an airflow within an additive manufacturing apparatus.SOLUTION: The invention provides a method, an apparatus and a program for additive manufacturing. An additive manufacturing device 300 includes a positioning mechanism configured to provide independent movement of at least one build unit 302 in at least two dimensions. The build unit 302 may further include a gas flow device for providing a flow zone in a first direction with relation to the build unit 302. The build unit 302 may further include a powder delivery mechanism and an irradiation beam directing unit. The irradiation bean unit may follow a first irradiation path, where the first irradiation path forms at least a first solidification line and at least a second solidification line formed at an angle other than 0° and 180° to the first solidification line.SELECTED DRAWING: Figure 7
