A method for casting an article comprises a first region and a second region. The method comprises casting an alloy in a shell, the shell having a casting core protruding from a first metal piece; and deshelling and decoring to remove the shell and core and leave the first region formed by the first piece and the second region formed by the casted alloy.

The present disclosure discloses a production line for ceramic shell making and a method for ceramic shell making. The production line may include a conveyor chain system, a robotic arm, a slurry coating device, and a sanding device. The conveyor chain system may be configured to convey a batch of modules. The robotic arm may be configured to replace and remove one or more modules among the batch of modules relative to the conveyor chain system and hold the one or more modules during a plurality of subsequent operations. The robotic arm may be configured to be moveable to a plurality of positions each of which corresponds to one of a plurality of stations. The slurry coating device may be configured to coat the one or more modules in slurry. The sanding device may be configured to sand the one or more modules.

The present disclosure provides a method of investment casting using additive manufacturing. In one aspect, the method includes: creating a digital model of a building component using one or more software tools executed on a computer device and importing the digital model in an additive manufacturing apparatus; producing a first physical specimen by controlling the additive manufacturing apparatus in accordance with the digital model; creating a first negative mold using the first physical specimen as a template, the first negative mold having a hollow space substantially defined by a surface profile of the first physical specimen; producing a second physical specimen using the first negative mold; creating a second negative mold enclosing the second physical specimen therein; producing a casting piece using the second negative mold; and finishing the casting piece to produce the building component.

A die cast system having an inner liner insert that enables the configuration of a component produced by the system to be easily changed by changing the inner liner insert without having to rework the die housing is disclosed. Because the inner liner insert only need be removed and replaced to change the configuration of an outer surface of a component produced by the system, the cost savings is significant in contrast with conventional systems in which the die would have to be reworked.

3-D printed PLA material of a selected density is formed into a pattern that is configured as the outer shell of a casting form to be used in the lost foam or evaporative casting process. The purpose of 3-D printing of the PLA material is used to maintain the proper configuration of the form to facilitate casting, and reduce buildup of carbon on the surface of the casting. Because the form is essentially hollow, PLA support pieces can be used on the interior to maintain the structural integrity of the form.
