Lost wax casting bonding methods and systems. A method for bonding a wax component in a feeder system for a lost wax casting process comprises embedding conductive nano-particles in wax to form a sacrificial susceptor. The method includes coupling the wax component to another component such that the sacrificial susceptor is at an interface of the wax component and the other component. The method comprises inductively heating the sacrificial susceptor to cause the wax of the sacrificial susceptor and at least a portion of wax of the wax component to melt to thereby form a bond between the wax component and the other component.

A directional solidification casting method includes fluidly coupling a feed line conduit with a source of molten metal and with a directional solidification mold at a gating. The mold has an interior chamber with a shape of an object to be cast using directional solidification in a growth direction. The feed line conduit is fluidly coupled with the gating in a downward direction oriented at an angle that is closer to the growth direction of the mold than to another direction that is perpendicular to the growth direction of the mold. The method also includes positioning a downstream portion of the feed line conduit below the gating, directing the molten metal into the mold via the feed line conduit, and casting the object in the mold using directional solidification.

A casting method using combined 3D printed shell mold and the combined shell mold used in the method. The method consists of shell mold making and casting steps. The shell mold is constructed by combination. First, the 3D printer at least prints out a runner part and several pattern die parts for molding products. In the print run, the first interfaces corresponding to the quantity of pattern die parts are printed out integrally on the runner part. The second interfaces corresponding to the first interfaces are formed on the pattern die parts. Afterwards, the first interfaces and the second interfaces are butted, the primary runner in runner part is connected to the die cavities in pattern die parts, the runner part and pattern die parts are combined to form a shell mold for casting multiple products at a time.
