Time waits for no man, and neither does the 3D printing world. We’re a little more patient at 3ders though, so here’s another round-up of recent developments you might have missed. Stories include an award being granted for 3D printed wind turbine blades, SLM Solutions getting its biggest-ever contract, and more besides.

Winners of the annual Federal Laboratory Consortium awards were recently announced, and the innovative 3D printing work of Sandia National Laboratories was recognized. The FLC awards program is intended to promote the achievements of federal laboratories and their industrial partners. In the case of Sandia, this is National Technology and Engineering Solutions of Sandia LLC, a wholly owned subsidiary of Honeywell International Inc. that operates the laboratories for the U.S. Department of Energy’s National Nuclear Security Administration.

Sandia - Oak - Ridge - National - Laboratory

Sandia collaborated with Oak Ridge National Laboratory on production of its 3D printed turbine blades, which won it a Regional Partnership Award from the FLC. The blades were designed to cut costs in the testing process for new blades. They were made to replicate the wake of a full-size blade, but on a much smaller scale. They were one third of the size of regular blades, and cost 95 percent less.

Major global 3D printing company ExOne, based in North Huntingdon, PA, has made a significant addition to its product portfolio for industrial 3D printing. Its production service center can now provide manufacturing clients with components made from 17-4PH stainless steel.

SAE - Type - UNS - S17400 - Stainless

Also known as SAE Type 630 and UNS S17400,17-4PH is a chromium-nickel-copper precipitation-hardening stainless steel that is commonly used for applications requiring high strength and a moderate level of corrosion resistance. Compared with other stainless steel alloys, it is also preferred for its weldability. After 3D printing, 17-4PH parts produced at ExOne’s production service center will be heat treated according to Condition H900 to...
