News Australia reported that Hank Haeusler, a senior lecturer in architecture at the University of New South Wales, said that it is technically possible to build a 3D printed house. The key is to find the right customers, developers, and contractors. By.
"I think this will definitely happen, and I think in five to ten years, we will see more and more 3D printed houses," he said.
Heisler said that researchers at the Royal Melbourne Institute of Technology (RMIT) have developed 3D printed structural nodes, which can be used to connect building components, such as connecting reinforced concrete walls. He believes that 3D printing technology has been widely used in industries such as automobile and aircraft manufacturing.
Although still in the experimental stage, the ability to build house components with 3D printing has been demonstrated, and architects are perfecting this technology.
Researchers at the University of Southern California developed a technology called Contour Crafting more than ten years ago. Professor Behrokh Khoshnevis said his goal is to be able to do so within 24 hours. Complete the whole house from the foundation to the roof.
He once said in 2003: "Our goal is to be able to complete the construction of a 185 square meter bungalow on site in one day, without human hands."
He hopes to develop a giant 3D printer, with which he can print a complete house in one go.
Koscheneves acknowledged that entry-level 3D printers for building houses will be on sale in the next few years, but a lot of testing is needed to get this technology certified.
He said: "People should understand that basic 3D printing can be used to build the basic shell of a house. A lot of things need to be built inside."
He said that under ideal conditions, using 3D printing technology to build a formal traditional house can save 10% of money. But building a simple house, such as a simple house for low-income people or an emergency shelter, will save even more.
Last year in China, Shanghai Yingchuang Decoration Design Engineering Co., Ltd. demonstrated 3D printing technology for building houses. They used what they claim to be the world's largest 3D printer to build 24 one-room houses within 10 hours. The cost of each house is A$6494. The company also claimed that they built a five-story building, making it the highest 3D printed building in the world.
Yingchuang used their four giant 3D printers to build the walls of the house, using recycled materials and concrete. The concrete is poured layer by layer, and the formed walls are assembled on site.
Koshineves claims that 3D printing technology has unique advantages and is feasible in architecture. Heisler also holds the same view.
"Time will tell whether 3D printing technology really saves money or not, but it can definitely design and build complex shapes," Heisler said. He said that, in fact, the biggest advantage of 3D printing technology is the potential to build non-standard shapes. If Jorn Utzon, the architect who built the Sydney Opera House back then, would build it now, he would definitely consider using 3D printing technology.
He said that with rising labor costs, 3D printing can eventually become a cheap way to build houses, but still using traditional materials such as concrete. At present, 3D printing technology for building houses is still far away from mass commercial applications. But if the cost of hiring manual construction continues to rise, one day maybe 3D printing technology will become an attractive option.
