17. A manufacturing process comprising:
-
adding a layer of a first powder to a table, the table made of a translucent material; disposing an external cross section of a partially formed part in proximity with the layer of the first powder; selectively melting the first powder to fuse with the partially formed part, thereby providing the partially formed part with a new external cross section; lifting the part above the remainder of the layer of the first powder; removing the remainder of the layer of the first powder from the table; adding a layer of a second powder to the table, wherein the second powder has a chemical composition different than the first powder; disposing the new external cross section of the partially formed part in proximity with the layer of the second powder; and selectively melting the second powder to fuse with the partially formed part. - View Dependent Claims (18)
