How does 3D printing works

The process of 3D printing, which is what created this likeness of the Star Wars character Yoda, has gained in popularity in recent years. There are several types of 3D printers, but all involve the same basic approach for “printing” an object: transferring a substance in multiple layers onto a building surface, beginning with the bottom layer.

A Dutch architect recently announced plans to construct a house using 3D printing, a technology that has been around for decades but has only entered the public consciousness in the last few years.

Janjapp Ruijssenaars, who works with the Amsterdam-based architecture studio Universe Architecture, recently announced his plans for Landscape House, a looping infinity building that he expects will be completed in 2014, according to the Guardian.

Expected to cost between $5 million and $7 million, the building will be made from 3D-printed pieces.

Frequently portrayed as a seemingly magical process, 3D printing — also called additive manufacturing — involves creating a solid object by layering thin slices of material including plastic, metal and ceramic.

Dutch architect Janjapp Ruijssenaars has proposed building a house using 3D printed materials. To do so, he plans to use a large machine that deposits sand and a binding agent in layers roughly five to 10 millimetres thick to create six-by-nine-metre sections of a stone-like material.

“It’s been in use for industrial contexts for at least 20 years,” says Matt Ratto, assistant professor at the University of Toronto and director of the information faculty’s Critical Making Lab.

However, 3D printing has caught the public eye over the last few years as the technology has become more refined, not to mention cheaper.

Some of the proposed uses have drawn widespread attention in the media, from the ability to manufacture gun parts at home to the creation of edible entrees from pureed foods.

Anyone hoping for a Star Trek-type “replicator” able to generate myriad objects of varying complexity will likely be disappointed, as the technology is typically used to test the fit and functionality of prototype models or pieces in manufacturing and design projects.
