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.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
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.
