Writing about additive manufacturing (AM) and the 3-D printing of gears is somewhat akin to publishing an updated dictionary. A new edition dictionary is literally already out of date before it hits Amazon's or your local bookseller's shelves. New words are coined and definitions are updated constantly. So it is with AM: The technology is evolving so quickly that technical papers and other sources of AM information require constant revision.

AGMA President Matt Croson explains how the association is here for members and the gear industry at large, providing information, resources, education and training -- even during the crisis.

In this edition of Arvin's Angle, Joe explains why training isn't an expense. It's an investment.

Welcome to a new era of Gear Technology magazine! AGMA is proud to add Gear Technology, Gear Technology India, Power Transmission Engineering, the Michael Goldstein Gear Technology Library and supporting websites and circulation under its umbrella.

As you've probably heard by now, Michael Goldstein, founder and Publisher since 1984, has stepped back from his day-to-day duties and transferred the operation of Gear Technology, Power Transmission Engineering and Gear Technology India to the American Gear Manufacturers Association.

When I started Gear Technology more than 35 years ago, my intention was to create something of lasting value for the gear industry. It was a way of giving back to the industry that had been so good to me and my family.
