Hoosier Pattern produced this video illustrating its use of 3D printing in sand to make cores and other mold components for casting.

Having this video is helpful to show customers, because—as we described in this article—the sand printing capability allows Hoosier to take a radical approach to casting. Instead of making the pattern and core box, the pattern shop can now skip this step altogether by printing the core and other mold components directly in sand. Design freedoms become easy to achieve that were never possible or practical before. Car maker Ford is making its own use of the same technology.

Also seen in this video (starting at around 0:35) are the statuettes used as spacers within the 3D nesting of printed components.
