Investing can often be characterized as mostly smooth growth with occasional interruptions of violent fluctuations, similar to being an airline pilot. Ninety percent of the job is uneventful to the point of automation; ten percent of the job is terrifying and requires complex skills and a flawlessly calm demeanor.
One of the original entrepreneurs in the 3-D printing world (Link)
Hans Langer founded Electro Optical Systems "EOS" over 30 years ago. Today, EOS’s 3-D printing machines have a base price as high as $1.6 million and fill the factory floors of companies like Boeing, BMW, Lockheed Martin and Siemens.
After receiving his Ph.D., Langer thought he would become an academic, but a professor convinced him he could make a bigger difference in industry. Early in his career while working at General Scanning, Langer proposed the company start their own 3-D printing division. At the time, 3-D printing was in its infancy and the board of directors said no and argued it was to risky. Langer had an idea that 3-D printing would one day be significant to the manufacturing industry as it could produce parts that would have been impossible using traditional manufacturing techniques. Convinced of his idea for 3-D printing he quit his job. In 1989, at age 36 with two young kids and just over $50,000 to his name, he founded EOS. Today he is worth an estimated $2.6 billion.
