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.
The grab bag of plastic and rubber materials featured in this new product slideshow are aimed at lighting applications or automotive uses. The rest are for a wide variety of industries, including aerospace, oil & gas, RF and radar, automotive, building materials, and more.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
