Abstract
Rotors formed by an additive manufacturing process are presented. In one example, a method of making a rotor is presented including defining a printing order for the application of a first material, and creating a plurality of lobes arranged helically about a central opening or a shaft by adding a first material in the printing order, wherein each of the plurality of lobes defines an outer surface.
Claims25
A method of making a rotor comprising:
- (a) defining a printing order for the application of a first material;
- (b) creating a first rotor end face by adding the first material in the printing order;
- (c) creating a plurality of lobes arranged helically about a central opening or a shaft by adding the first material in the printing order, each of the plurality of lobes defining an interior cavity;
- (d) creating a second rotor end face by adding the first material in the printing order to at least partially enclose the interior cavity defined by each of the plurality of lobes;
- and
- (e) creating an abradable coating by adding material onto the outer surface of the plurality of lobes.

A method of making a rotor comprising:
- (e) defining a printing order for the application of a first material and a second material;
- (f) creating a first rotor end face by adding the first material in the printing order;
- (g) creating a plurality of lobes arranged about a central opening or a shaft by adding the first material in the printing order, each of the plurality of lobes defining a convex shaped outer perimeter and defining an interior cavity located at least partially within the convex shaped outer perimeter;
- (h) creating a second rotor end face by adding the first material in the printing order to at least partially enclose the interior cavity defined by each of the plurality of lobes;
- and
- (i) creating an abradable coating by adding the second material onto an outer surface of the plurality of lobes.
