Dutch 3D printing technology firm MX3D is close to beginning construction on its stainless steel, 3D-printed pedestrian bridge in Amsterdam.
We wrote about the bridge and its design in 2015. MX3D Co-Founder and CMO Gijs van der Velden recently explained to me at the Autodesk University trade show in Las Vegas where the project is at and why they expect construction (via giant welder robots who will weld individual parts “printed” in mX3D’s facility together) to start in early 2017.
“We’re at the point where we’ve printed every critical part of the bridge and all we need is approval from the engineers,” van der Velden said. “Our design is quite elaborate and all the diameters change everywhere and we use 3D printed parts. We’re getting pretty close and once they approve we have agreed with the City government that once we do a full load-bearing test it will be acceptable. It’s not the normal procedure but the city was very helpful in accommodating us.”
The bridge, which will be made of stainless steel 316 alloy, will be installed in a public park in Amsterdam and cross one of the city’s famous canals.
“(We chose 316 stainless) because it’s highest grade standard and not too expensive,” van der Velden said. “We want to make this technique available for other professions — other than aerospace (where it’s already being used) — so, we want to work in steel, stainless steel, bronze, aluminum.”
