Stars and stripes in 3-D printing

Posted on Updated on

Hi Friends, I am writing this article. This is Mr. GP Cox’s nice suggestion, the article in Stars and stripes about 3-D printing used in the maintenance of a Lockheed-Martin F-22″.
Thank you to Mr. GP Cox:)

According to Rick Ambrose, Lockheed Martin Space executive vice president, “Our largest 3-D printed parts to date show we’re committed to a future where we produce satellites twice as fast and at half the cost. And we’re pushing forward for even better results. For example, we shaved off 87 percent of the schedule to build the domes, reducing the total delivery timeline from two years to three months.”

Evonik’s €400 million project

Posted on Updated on

Whenever plastics are exposed to high stress, polyamide 12 from Evonik is the answer- in oil and gas extraction, automotive engineering, medical devices, or 3D printing. Evonik produces the high-performance plastic in two forms-as it is VESTAMID line of granulates and it’s VESTOSINT powder.

According to Dr. Ralf Düssel, the Head of the High-Performance Polymers Business Line at Evonik, “This project is a special challenge, the Group’s PA12 granules, and powders. This Evonik’s engineering unit has some 80 engineers are working on the project. We have also contracted a well-known, globally active technical service provider for the detail engineering of individual sub-projects. The Marl Chemical Park offers us optimal conditions for this extraordinary feat. Once we start up the new facility, the existing structures that have been in place for over 50 years will be used for product distribution.”

NASA’s 3D Printed sensor technology

Posted on Updated on

According to Mahmooda Sultana, Associate Branch Head, Systems Engineering Branch at NASA’s Goddard Space Flight Center in Maryland, “Mahmooda uses her love of math and puzzles to develop new technologies and miniaturize instruments for NASA missions. 3D printing allows technicians to print a suite of sensors on one platform, dramatically simplifying the integration and packaging process. These tiny platforms could be deployed on planetary rovers to detect small quantities of water and methane, for example, or be used as monitoring or biological sensors to maintain astronaut health and safety”.
