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.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
LeMond Composites, founded by three-time Tour de France cycling champion Greg LeMond, is the first to license a new carbon fiber production method invented by Oak Ridge National Laboratory (ORNL) that's faster, cheaper, and greener.
This month will mark the launch of the SpeedFoiler, a super-fast, ultra-lightweight foiling catamaran that can fly short distances over water faster than other foiling designs, in part because of its carbon composite materials.
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.
