A casting assembly includes a core body extending along an axial direction between a first end and a second end, the core body having a core interior surface and a core exterior surface, with the core exterior surface shaping a part surface of a cast part. The core interior surface at least partially bounds a hollow cavity. The casting assembly also includes a shell body extending along the axial direction and having a first shell surface and a second shell surface, with at least a portion of the second shell surface facing the exterior surface of the core body.

Casting assembly

A casting assembly includes at least a first body and a second body. The first body can be a core and the second body can be a shell. The first body has a first interior surface and a first exterior surface. The second body has a second interior surface spaced from a second exterior surface. A portion of the second interior surface is spaced from and facing the first exterior surface. The first body having a casting hollow, where the casting hollow is at least partially defined by the first interior surface.

Partial integrated core-shell investment casting molds that can be assembled into complete molds are provided herein. Each section of the partial mold may contain both a portion of a core and portion of a shell. Each section can then be assembled into a mold for casting of a metal part. The partial integrated core-shell investment casting molds and the complete molds may be provided with filament structures corresponding to cooling hole patterns on the surface of the turbine blade or the stator vane, which provides a leaching pathway for the core portion after metal casting. Core filaments that can be used to supplement the leaching pathway, for example in a core tip portion of the mold are also provided herein.

Method for making an integrated core-shell structure

Multi-piece integrated core-shell structure for making cast component

The present disclosure generally relates to additive manufacturing of an object using both a digital light processing (DLP) projector and a focused energy source to irradiate a photopolymerizable material, and apparatuses and methods for the same. The DLP projector irradiates and cures an outer perimeter of the object, and the focused energy source irradiates and cures an inner region of the object. In a preferred embodiment, irradiation by both the DLP projector and the focused energy source occur from underneath a tank holding the photopolymerizable material and through a transparent window.

Hybridized light sources

This invention relates to a product and a method of preparing ceramic and/or ceramic hybrid materials through the construction of a printed die. The printed die being made by three dimensional printing or additive manufacturing processes possesses both an external geometry and an internal geometry.
