Ally, Not Adversary I


n the larger additive world, a lot of attention is given to intricate 3-D printed pieces in plastic or metal. They are meant to showcase


the amazing geometries achievable by printing a part directly and skipping traditional manufactur- ing steps. It’s a shame this can overshadow metalcast-


ing, which has been creating complex shapes for decades, arguably even centuries. And it’s a shame I’ve had conversations with individuals outside of the metalcasting industry who assume additive manufacturing is going to put the industry out of business. So when


I talked with Andreas Bastian, an engineer and research scientist, for our Casting of the Year ar- ticle on page 28, this quote was music to my ears:


Additive


manufacturing is having an impact on metalcasting.


“Metal printing likes to show all these exotic shapes that can be produced, but we want to demonstrate casting is a technology that is quite well suited to those shapes, particularly when you are making something larger than a bread box. Metalcasting offers hundreds of materials to choose from compared to metal printing, and the manu- facturing base is mature.”


Yes. Additive manufacturing is having an impact


on metalcasting and it’s not the death blow some were imagining. Foundries are learning how to use this technology to improve their traditional part development while still giving customers castings that meet rigid, often safety-critical, requirements. While some would argue the adoption of 3-D printing in our industry has been too slow, it is occurring—and at a growing pace. Investments are being made across the industry in 3-D printing sand molds, wax patterns and hard tooling and last year, AFS created an offi cial additive manufactur- ing division with specifi c committees for all three opportunities. T e committee has been active, and


a conference on the topic will be held Sept. 10-13 in Louisville, Kentucky. Additive can help low


volume and prototype metalcasters work faster and enable customers to wield more design muscle for stronger, lighter parts that are easier to manufacture. Parts like


this year’s Casting of the Year—a swing arm cast by Tooling & Equipment Interna- tional—help throw up a blinking neon sign to metalcasting and its capabilities. T e geometry may look like the typical direct metal printed examples we always see, but it’s not. It’s a metal casting produced in a proven manufacturing process in a


common, standardized alloy. Design engineers have to like that. On a separate note, Modern Casting recently


launched an updated website along with the revamped AFS website that was activated last month. The magazine website has a modern look, with an emphasis on getting more con- tent and related graphics on the main home page. Navigation has been simplified. Most ex- citing, the new platform is much more mobile friendly and easier to access when you’re away from your desk. Take a look; the url is still www.moderncasting.com.
