1-20. (canceled)
A method for 3D printing a fan wheel, comprising:
- generating a printing code for the fan wheel, the fan wheel including a hub and a plurality of blades extending outwardly from and supported by the hub, each of the plurality of blades having a root section;
- and
- manufacturing the fan wheel using a 3D printer system based on the printing code, wherein the manufacturing includes printing the root section of each of the plurality of blades into the hub, such that the root section of each of the plurality of blades is integrated into the hub, forming a continuous structure without attachment features.
A fan assembly, comprising:
- a 3D-printed, monolithic fan housing, manufactured as a single, seamless component without any welds, the fan housing including an external housing component and an internal housing component that cooperate to define an annulus, with one or more stator blades extending between the internal housing component and the external housing component, the one or more stator blades and the fan housing formed as an integrated structure to reduce manufacturing complexity;
- an electric motor at least partially housed within the internal housing component;
- and
- a fan wheel operably coupled to the electric motor and positioned in fluid communication with the annulus, the fan wheel including a hub and a plurality of blades extending outwardly from the hub, each of the plurality of blades having a root section printed into the hub, wherein the root section of each blade is integrated into the hub to form a continuous, monolithic structure without attachment features.
