不锈钢“3D打印”自行车
Need a bike? Print one up. Yeah, I know. It’s not exactly new to see custom-made 3D printed bicycles- back in 2015 Italian design studio Eurocompost unveiled their Bhulk MTB bike frame made out of recycled PLA filament and Portland-based Industry lifted the curtain on their titanium 3D printed, ‘connected’ bike Solid. While both of these are similar in how they were manufactured–printed in pieces first and then assembled together–a team of Dutch students from the Delft University of Technology has created their own version using a multi-axis 3D printing robot.一家工业设计公司发布了它们的3D打印自行车，准确地说是钛合金材质的自行车架。来自代尔夫特理工大学的荷兰学生们最终完成了这件作品，用的PLA材料作幕布，即聚乳酸,是由玉米和木薯等植物‘变’的,植物经过多道工序提炼出淀粉,经微生物发酵成乳酸,再聚合成聚乳酸
The students employed a unique 3D printing method from MX3D to create their Arc Bicycle. MX3D Metal is the melding of an industrial robotic arm and a welding machine, using a rapid prototyping process known as Wire and Arc Additive Manufacturing (WAAM). The process works as it sounds. An arc welder deposit metal one layer at a time on top of one another. Surprisingly, the process goes fairly quick.
学生们使用了MX3D公司的技术，这家公司2015年6月，在阿姆斯特丹市利用3D打印和焊接机器人建立一座大桥。
Using MX3D Metal allowed the team to print their bicycle right on the tabletop as the WAAM process in conjunction with the robotic arm eliminates the need for support structures or building plates with the metal solidifying as the form is being created. This also allows for larger builds over conventional 3D printing as space is limited only by the robotic arm’s reach. While the frame itself may look like it could bend and contort while being ridden, looks can be deceiving. The team took the 26-pound bike for trial rides around Delft’s cobblestone city streets with no issues what so ever.
MX3D技术允许你在桌子上打印
Of course, the Arc Bicycle is just a design concept and not for mass production but the team hopes others with be inspired by their design and build their own. MX3D is also using larger WAAM robotic printers to print a stainless steel bridge in the heart of Amsterdam, in an effort to prove they can create an intricate, structurally sound bridge using the very same process.

当然了，这个自行车行为艺术表达的是一种设计理念，而不是量产工艺。
真不错，有一台这样的打印机好方便。 也就是打印了一部分车梁，然后组焊 zms9439 发表于 2016-2-22 09:17 static/image/common/back.gif

是不是受限于打印机的大小
现在的3D打印并不能完全代替传统工艺，有一部分工艺不能达到传统工艺所能达到的要求呀 3D打印没能量产，价格高，其实这就是商机 用成熟的工业机器人来打印也是不错的方法。
