Abstract
An additive manufacturing apparatus is disclosed. The additive manufacturing apparatus includes a linear rail having a length. The linear rail is one of rotatable or revolvable in a horizontal plane about a vertical axis. The additive manufacturing apparatus further includes an electromagnetic energy source movably coupled to the linear rail and movable in a polar coordinate system having a radius R.
Claims56
An additive manufacturing apparatus comprising:
- a linear rail, having a length L1, wherein the linear rail is one of rotatable or revolvable in a horizontal plane about a vertical axis A;
- an electromagnetic energy source, movably coupled to the linear rail and movable in a polar coordinate system, having a radius R;
- a powder-containment compartment, configured to contain a metal powder and having a powder-bed volume;
- a build platform, at least partially delimiting the powder-bed volume of the powder-containment compartment;
- and
- powder-removal vents, located on the build platform within the powder-bed volume of the powder-containment compartment and defining a passage through the build platform, wherein the powder-removal vents are selectively openable to discharge the metal powder from the powder-containment compartment through the build platform.
