Oct 29, 2015A team of five TU Delft students are working on 3D-printing a bicycle. Advantages of a 3D printed bicycle is that the bike can be made exactly every individual’s specifications and it is cheaper than a traditional bike.The bike frame is made out of stainless steel, newspaper AD reports. This means it is heavier than the current aluminium bikes. But that does not mean this will always be the case – 3D printers are capable of working with all kinds of organic forms and using different materials can result in a lighter bicycle.This bicycle is the successor of the previously 3D printed bridge, which will be placed in Amsterdam in 2017. It forms part of a collaboration between Technical Universities and the Amsterdam Institute for Metropolitan solutions, in which TU students work on printing practical objects from everyday life.“We are now printing full-time”, Stef de Groot, one of the students working on the bike, said to the newspaper. “I expect the bike will be complete in two to three weeks.”This is still just an experiment however. Commercial production is still far in the future, according to Jouke Verlinden, professor of Industrial design at the Technical University.
26/10/2015...For safety the printing was totally enclosed in dark welding curtains to protect the visitor’s eyes. We managed to stick a poster of renders of the bike to one of the welding curtains so that people could at least see what we were printing even if it was not possible for them to watch the printing itself...
...a functional prototype is already in the works, and was revealed today at the Detroit Auto Show, where its four-wheeled, Wall-E-esque body zipped around on the showroom floor. In order to ensure that the Audi Lunar Quattro is rugged enough to withstand a lunar landing and then continue to face the elements throughout its journey, Audi and the Part Time Scientists have been working with metal 3D printing technology, constructing nearly the entire rover out of 3D printed aluminum and titanium.3D printing also enabled the scientists to manufacture special hollow structural components to route the wiring—something that would not be possible with CNC milling or other traditional manufacturing techniques. “It's not possible from the axis of freedom," said Robert Böhme, CEO of PT Scientists. "The parts are like one millimeter thick.”..
..showcased the first ever 3D printed object from asteroid metal as a sort of proof-of-concept of what might be common in space mining in the future.The raw material used for the 3D print was taken from an asteroid sourced from the Campo Del Cielo impact crater in Argentina and is made up of iron, nickel, and cobalt. From there, parts of the asteroid were pulverized and powdered..
