It seems just about anything these days can be produced with a 3D printer, including a house and parts for spacecraft and racing cars. Bridges can be added to the growing list, writes Daniel Michaels for the Wall Street Journal. “Additive manufacturing, better known as 3-D printing, has found eager adopters in transportation thanks to the technology’s ability to produce strong, lightweight parts in almost any shape,” writes Michaels. And 3D printed construction is most valuable with structures customized for a specific location. 3D-printed bridges can be found in the Netherlands, China and Spain. This summer, Dutch tech startup MX3D installed an artistic bridge, printed from stainless steel, across a canal in Amsterdam. “Every bridge is different,” the company’s CEO told Michaels.
