3D-Printed Future Has Already Come

Of course, you have heard about using 3D printers in bioprinting, building houses or just for fun. Keep reading to find out how 3D printing is used in creating bridges, planes and even rockets.

1. ‘World’s first’ 3D printed bridge opened in Brabant, Netherlands

Dutch officials reported about the opening, as they called it, the world’s first 3D-printed concrete bridge for cyclists.

“The bridge is not very big, but it was rolled out by a printer, which makes it unique,” Theo Salet, from the Eindhoven University of Technology, told Dutch broadcaster NOS.

“Searching for a newer, smarter approach to addressing infrastructure issues and making a significant contribution to improving the mobility and sustainability of our society” – said the head of BAM, Marinus Schimmel.

The work on its printing started in June 2017. It needed three months to build the bridge.

Should be mentioned that the Netherlands is among countries, with the United States and China, taking a lead in the cutting-edge technology of 3D printing, using computers and robotics to construct objects and structures from scratch.

Meanwhile, the first in the world pedestrian 3D-printed bridge was opened in December 2017 in Madrid. The Institute of Advanced Architecture of Catalonia (IAAC) was in charge of the architectural design of the bridge, which has a total length of 12 meters and a width of 1.75 meters.

2. Boeing 3D Printed Parts – would you venture to fly?

In spring 2017, Reuters wrote that Boeing will cooperate with Norwegian company Norsk Titanium to create 3D-printed parts for its 787 Dreamliner jet airliner. For the first time, Federal Aviation Authority approved using such  3D-printed structural components.

The reason Boeing is experimenting with 3D printing is that 787 model claims more metal comparing to other planes. Such innovative decision could save up to $3 million in construction costs on each jet built.

Titanium has many benefits as it is strong, lightweight, and helps to keep the plane fuel efficient. The point is that titanium is seven times more expensive than aluminum, which is widely used in commercial jets.

3. Just print the rocket and launch to space

Space industry also follows the tendency to use 3D printing in developing some components or even for creating a rocket.

For example, NASA developed 3D printed rocket details using two distinct metal alloys for the first time ever. Before that  3D printing rocket components have all been composed of a single metal. The opportunity to combine metals allows decreasing the cost of building rockets and make them stronger.

Furthermore, Elon Musk announced making with the help of 3D printing some components for Raptor engines, that is used in BFR (Big Fucking Rocket).  “We developed a new metal alloy for the oxygen pump that has both high strength at temperature and won’t burn,” Mask said while answering questions on Reddit.

Moreover, Relativity Space Inc. – startup company created by Tim Ellis and Jordan Noone, spent two years to build a rocket using only 3D printers. They believe that 3D printing technology will make rockets cheaper and faster to produce.
