NASA Will Use Stratasys 3d Printer to Make Mars Lander Door

NASA has announced that a new partnership, Stratasys of Eden Prairie and Phoenix Analysis & Design Technologies are teaming with Lockheed Martin Space to make a 3D printed hatch door for NASA’s Orion spacecraft.

 

This is a new venture for Stratasys which traditionally makes 3D printers and component parts for automotive, aerospace, industrial and medical device firms. The Stratasys printed materials that Lockheed selected includes high-strength resins and Antero 800NA electrostatic dissipative plastic materials offer high-performance mechanical chemical and thermal properties according to officials.

 

Stratasys was founded in 1989, by S. Scott Crump and his wife Lisa Crump in Eden Prairie, Minnesota. Crump’s idea for the technology came to him in 1988 when he decided to make a frog for his young daughter by using a glue gun with a mixture of polyethylene and candle wax in creating the shape layer by layer and of a way to automate the process. Four years later in 1992, Stratasys sold its first product, the 3D Modeler.

 

In October 1994, Stratasys had an initial public offering on the NASDAQ; they sold 1.38 million shares of common stock at five dollars per share. In 1995, Stratasys bought IBM’s rapid prototyping intellectual property and other assets. They also employed 16 former IBM engineers who’d been developing a small 3D printer that relied on extrusion system similar to Crump’s patented fused deposition modeling technology. Continue reading

Why I Admire the Mayo Clinic

Last September I had my annual physical with my personal physician of 30 years, Dr. Dean Kahoi, and he noted that I had an abnormal gait in my walk. He suggested that I make an appointment with a neurologist which I did. I met with Daniel J. Kuyper, MD and he did some basic tests and ordered up MRIs of my brain and neck. The outcome of the MRIs was my brain was happily all right but I did have spinal stenosis.

 

In November, I met with a neurosurgeon from Minneapolis-St. Paul. My wife, Corrine Foley, was in attendance with me. The doctor showed me where I was having some strength difficulties and some muscle loss and proceeded to show me from my MRIs where the stenosis was occurring. He recommended that I have a couple of discs removed and then a couple of weeks later have additional surgery to scrape bone away from my spine. The discs would be removed from the front by opening my throat and then the scraping would occur from the back of my neck by cutting through muscle. In other words it would be a two surgery procedure. Continue reading
