The Most Incredible Constructions Printed In 3D in the World

We review some of the most unusual and spectacular printed3D constructions made to date throughout the world, with applications from environmental to industrial.

One of the great topics of discussion in the technological arena is being 3D printing. It is a form of additive manufacturing with which we can produce any element in just a few minutes without further preparation than a digital design previously sketched or scanned.

So much is the hype that is being generated around 3D printing that it is even estimated that this technology will move an associated industry of no less than 26,700 million dollars in 2019 according to IDC.

But up there the theory and the big numbers. What is truly impressive comes when we bring this concept of 3D printing to fruition in concrete use cases that already exist between us.

Therefore, we have compiled seven buildings and devices manufactured with 3D printing that promise to revolutionize from urban structures to health, through mobility or space exploration.

Houses printed in 3D in Valencia

We started this particular compilation in Spain, more specifically in Valencia, where four young people from the PolytechnicUniversity of Valencia created the startup Be More 3D, responsible for the first single-family houses printed in 3D.

Built in-situ, these modular buildings are made of concrete, as if it were a house to use. His first design, a pioneer also on a world scale, consisted of a house of 24 square meters, although now they are able to print houses of up to 70 square meters in about 10 hours. Its cost? 55,000 euros.

3D printed bridges in Shanghai

We go a little further, to China, to delight our eyes with this bridge printed in 3D that has been installed in the central park of Taopu, in Shanghai.

The structure, manufactured in 35 days based on plastic and fiberglass, measures 15.25 meters long and 3.8 wide. It is able to withstand the inclement weather, withstand up to 250 kilos per square meter (four adults per square meter) and its useful life is estimated in approximately three decades.

Artificial coral reefs

And if we go down to the bottom of the ocean would we also find objects printed in 3D? The answer is affirmative: in the Maldives Islands a series of artificial coral reefs have been installed that were built by additive manufacturing.

Cast in ceramics, these 3D printed reefs consist of 220 molds that are submerged seven meters below the surface and their purpose is to serve as a base to transplant live coral that will grow in two or three years around this material.

In this way, the ideologists of the project (an Australian company called Reef Design Lab) want to save the corals from global warming and environmental pollution.

Mannequins to try radiotherapy treatments

To save the planet to save human lives. We are talking now about Marie, a 3D printed mannequin that has been designed by a student at Louisiana State University to measure the effects of radiation in real time and determine the optimal dose of radiotherapy sessions in the treatment of cancer.

Marie is a scale replica of the human being, made of biplastic: it measures 1.8 meters, weighs 7 kilos and can store up to 136 liters of water inside. It was printed in 136 hours and its value lies in allowing the effects of these treatments to be experienced in people who currently do not find artificial replicators in laboratories, such as women and children.

Fully functional electric motorcycles

But 3D printing will not be a part only of fixed structures and buildings, but will also roll on our roads. Thus, the consultant Now Lab has already developed the first electric motorcycle completely made in an additive way, including not only the chassis, but also its tires, suspensions, tires or seat.

Nera, that's the name of the vehicle, is nothing more than a prototype but opens the window to endless possibilities within the automotive industry. Only the electric motor has been left out of 3D printing for obvious reasons.
