Abstract
Described are techniques for additive manufacturing with magnetic manipulation. The techniques including a method comprising performing additive manufacturing using a material containing a ferromagnetic additive to create a component. The method further comprises, during the additive manufacturing, generating a magnetic field near a portion the component, where the magnetic field causes the portion of the component to deform during the additive manufacturing based on the material containing the ferromagnetic additive.
Claims19
A method comprising:
- performing additive manufacturing using a material containing a ferromagnetic additive to create a component;
- and
- during the additive manufacturing, generating a magnetic field near a portion of the component that is structurally unsupported, and wherein the magnetic field supports and deforms the portion of the component during the additive manufacturing based on the material containing the ferromagnetic additive.
A three-dimensional printer comprising:
- a platform;
- a nozzle for printing a component on the platform using a material containing a ferromagnetic additive;
- and
- a plurality of inductors surrounding the platform, the plurality of inductors configured to receive electricity during printing the component to deform the component by generating a magnetic field that interacts with the ferromagnetic additive.
