这不算什么新创意，但是从去年开始，3D打印重新变得炙手可热起来：2007年，当彼得在皇家飞利浦电子公司（Royal Philips Electronics）的孵化器里创办这家公司时，他要打印一个自己设计的iPhone手机壳需要支付高达500美元的费用。而现在在Shapeways公司，一个设计师只需付约20美元就够了。正是看到了这一前景，近期安德森•霍洛维茨基金（Andreessen Horowitz）领衔向该公司投资了3000万美元。
A short subway ride from Midtown Manhattan, Peter Weijmarshausen is building a factory that reimagines mass production. Weijmarshausen is the co-founder and chief executive of Shapeways, a company that lets people design and order objects printed on high-end 3-D printers.
It's not a new idea, but in the last year 3-D printing has become newly available: In 2007, when he first started the company within the incubator of Royal Philips Electronics, Weijmarshausen would have paid as much as $500 to print a self-designed iPhone case, for example. At Shapeways today, a designer will pay around $20. This promise recently spurred Andreessen Horowitz to lead a $30 million round of funding in the company.
It's hard to imagine how a machine could "print" an iPhone case until you've seen it. So, last Friday afternoon a group of Fortune reporters and editors headed out to Long Island City for an inside look a the mass manufacturing technique considered so promising that President Obama called it out in his January State of the Union speech.
The Shapeways factory officially opened last fall, but it's still under construction. We passed through the administrative area where a half-dozen Brooklyn designer types were fulfilling orders out to the factory floor where nine machines are up and running so far. When the factory is complete, there will be as many as 50.
In front of us, one of these hulking machines gives off heat. It's the size of a refrigerator; inside, a rectangle tray the size of my favorite chili pan is being filled layer-by-layer with dust. We push our noses up to the small window to watch: A layer of dust is spread. Then, a laser burns a series of lines into the dust, heating it to the point of almost melting to form the object. It will take 24 hours for this chili-pan size tray to be complete.
For now, the Long Island City factory only prints materials in a white nylon plastic, though that will change in time. Shapeways is able to manufacture in other materials -- stainless steel, sandstone, ceramics -- from its other facilities. The company also has offices in Seattle and Eindhoven in the Netherlands.
A diagram of the tray's contents hangs to the right of each printer. Weijmarshausen explains that Shapeways maximizes each tray by pairing elements of different customer orders. These diagrams look like a cross between a 3-D sonogram and a katamari. This optimization brings the price down. Once the tray is completed, employees bring it over to a post-production area where they remove all the dust that hasn't been sealed by the laser. The result is a jumbled collection of parts that are cleaned and separated and buffed, much like bone-hunting archeology. Depending on the order, many are also dyed in bright hues.
