Producing the worlds first 3D-printed bridge with robots "is just the beginning" - Joris Laarman
The technology that startup MX3D is developing to 3D print a bridge in Amsterdam could be used to produce «endless» different structures, says Dutch designer Joris Laarman in this exclusive movie.
MX3D is a new research and development company co-founded by Laarman and Tim Geurtjens, which plans to use robots to produce the worlds first functional 3D-printed steel bridge over an Amsterdam canal by 2017.
«The basics of the technology is pretty simple,» Laarman explains in the movie, which was filmed at MX3Ds workshop in Amsterdam. «Were using an industrial robot that is usually used in assembly lines in the car industry. We have combined this with a welding machine and our own software to have it 3D print in metal.»
The six-axis robots that MX3D are adapting are able to rotate their arms along six different planes of movement. They build up structures by depositing small quantities of steel in layers.
Unlike traditional 3D printers, robots can produce much larger structures by moving across them as they print.
«Youre not limited by size, so we can theoretically print endlessly big,» Laarman says.
The steel footbridge will span eight metres. MX3D originally intended to print the bridge in situ, but had to abandon that plan over health and safety concerns. Laarman and his team will now reconstruct a section of the canal in their workshop to demonstrate that it could be done on site.
The bridge will be printed in one piece, with the robots printing a load-bearing structure to support their own weight as they work.
«The bridge is going to be fairly small – its a pedestrian bridge,» Laarman says. «Its still a huge challenge, because we want to print it in one go. We want the robots to print their own support structure as they move over the water.»
