他喜欢编程，很小就开始玩电脑。后来他在埃因霍温科技大学（Technical University of Eindhoven）学习应用物理，期间依然对计算机热情不减。上世纪90年代，互联网出现之后，对开源程序充满热情的魏玛沙汉开始加入初创公司。尤其是3D建模和后来的3D打印领域。魏玛沙汉说：“有了3D打印，人们面临的唯一限制就是自己的想象力。”
Peter Weijmarshausen grew up in the Netherlands. Even as a child he had an entrepreneurial spirit, and he always found ways to make money, building businesses such as a car washing service and lawn care for neighbors.
He loved coding and started playing with computers at a young age. When he went to study at the Technical University of Eindhoven, he studied applied physics and kept up his interest in computers. After the Internet emerged in the 1990s, Weijmarshausen began to join startup companies, fueled by his passion for open source software. That was especially true for 3-D modeling and, eventually, 3-D printing. "With 3-D printing, your imagination is your only limitation," Weijmarshausen said.
He and his fellow co-founders began to build Shapeways -- an online 3-D printing marketplace -- in March 2007. People can make, buy, and sell 3-D printed products through the site, and Weijmarshausen's goal is to make it easy for people to create unique products. Weijmarshausen, 42, is based in New York. He spoke with Fortune.
1. What business or technology person do you admire most? Why?
One of the companies that jumps out at me is Amazon (AMZN). From what I can tell, they really put their customers in the center. They want to make a company that values their customers, and they don't have huge margins. What they do every time they have an improvement in their service that reduces their cost, they give all of that value back to their customers. They give the customer an ever-better value for their money.
That resonates well with me. That's how you can build a truly magnificent experience that is compelling for an enormous amount of people. It's not about making a few dollars quickly. It's about building a sustainable business that makes all of its customers happy and provides true value. If you do that, then, in the end, as a business you're also making money, lots of money. But it's first and foremost about the customer and getting them the most value. And of course the people that work with Jeff Bezos are supporting that vision. And in the beginning, a lot of people were very skeptical or cynical about it. But he's prevailed, and he's built an amazing company. That's quite something.
2. What technology sector excites you most?
It probably won't surprise you that I'll say 3-D printing. It has the ability to truly disrupt the way we think about products. Way back in the 1800s and before, products were made by hand. And then came along the industrial revolution where we had mass manufacturing. Mass manufacturing has given us a lot of really cool products, but they're all the same. What 3-D printing brings on top of mass manufacturing is the ability for the individual to get the exact product that they want and not just what is available.
To me, that is such a compelling concept. It takes a while to really grasp because it's no longer big corporations that figure out what you might want by deciding what is the lowest common denominator and mass-producing it. No -- it's you who has an idea for what you want. Our job is to make it easy for you to express what you want, and then we'll make it for you at a reasonable price. Isn't that what it's all about? Not that you get pushed into buying certain things, but that you can decide what you want. Whether it's clothing or jewelry or gadgets, it doesn't really matter. The ability to truly influence the products that you get, that's the power that 3-D printing brings.
3. Is business school necessary for entrepreneurs?
I didn't go to business school, and I think I'm a pretty good entrepreneur. I see a lot of entrepreneurs who didn't go to business school. I think maybe you aren't born an entrepreneur, but it's something that you start acting on early in life. Even as early as before 10 years old, it's like this freedom that people feel. Why would I get a job if I can start doing things in a smart way? I always found projects or opportunities to make money instead of jobs. It's a way of thinking that at some point you have to get, then you get better at it. As a company like Shapeways becomes bigger and bigger, you have to learn a few things. Like how do you advance and expand into marketing. Software engineering was already in my blood, and I studied applied physics, so I understood the technology really well. Business school can help you get the framework and context even better, but if you're open to learning, you can do it perfectly well without business school.
