GE Aviation, Lockheed & Optomec Star in Metal 3D Printing Project
The Anniston Army Depot repaired components of the Abrams M1 Tank AGT1500 engine using an Optomec LENS 3D printer, eliminating the high-heat welding process used with traditional methods that can cause distortion effects. This process is now the subject of a $4 million Optomec-headed America Makes project for the Air Force. (Source: Anniston Army Depot)
Really like the direction this program is taking with creating spare parts for legacy flight programs through the use of 3D printing. Since the fabrication of these spare parts is typically high mix and low volume, in many cases, this will prove to be an outstanding fit.
Aside from prototyping and, in some cases, end-production manufacturing, one of the most promising use cases for metal 3D printing and additive manufacturing is for repairing high-value components. But additive manufacturing techniques are not created equal for any of these. The conformal layers that can be achieved with the LENS process on non-flat surfaces of parts makes it stand out for this application.
Major changes are happening in the world of 3D printing and additive manufacturing materials, machines, and software. If the industry -- and the design engineers and OEMs it serves -- are to grow, all three areas must become much more tightly integrated.
The FDA has just released draft guidelines for using 3D printing in the design, development, and manufacture of regulated medical products. Although the recommendations are non-binding, they do set some much-needed parameters.
HP's industry-changing 3D printing announcement for commercial-scale end-production wasn't the only news of note at RAPID 2016 this week. Here are six more game-changing software and hardware news items, plus some videos explaining HP's technology.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
