3D Printing As an Alternative to Pattern Making

Posted by Hill and Griffith Company on Jan 26, 2021 9:16:21 PM

3D printing has eliminated much of the tedium of the 3,000-year-old sand casting process

Excerpt from the January 2014 Additive Manufacturing article by Peter Zelinski.

Hoosier Pattern has changed its business in a way that dramatically expands the design freedom available to its customers. Historically, the company has machined foundry patterns. Today, it uses 3D printing to create molds and cores directly from sand.

That's sand casting in a nutshell, although journeyman pattern maker Dave Rittmeyer will tell you there's far more to it than that. Rittmeyer, the customer care and additive manufacturing manager at Hoosier Pattern Inc., Decatur, Ind., also will tell you the industry has undergone a dramatic shift over the past decade or so, thanks in part to AM.

Casting Goes Digital with Sand 3D Printing, Nondestructive Testing

Posted by Hill and Griffith Company on Jan 12, 2021 5:04:14 PM

Tooling & Equipment International (TEI) used to make tooling for castings. Now, it casts prototype parts in a digital workflow using 3D printed sand molds in combination with simulation software, CT scanning and X-ray technology.

Excerpt from the January 2019 Additive Manufacturing article by Stephanie Hendrixson.

"In the early days, before numerically controlled machines, casting tools were made by highly skilled pattern makers carving mahogany into patterns and packing sand around them," says Oliver Johnson, president of Tooling & Equipment International (TEI). "You'd be talking six or nine months to make all the tooling for a part that we could do today with a 3D printed mold in two days."
