The reasons are: 1. Today’s 3D printing construction machines are relatively large. The larger the machine, the worse the printing details; 2. The on-site assembly work will return to labor-intensive, which increases the cost. Cost; 3. The technology is not yet mature. Even if the product can be produced, it is difficult to mass-produce it and will break when dropped.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
1. Today’s 3D printing construction machines are relatively large. As the machines get bigger, the difficulty and cost of manufacturing the machines themselves are increasing. At present, the larger the machine, the worse the printing details.
2. 3D printing modularization, each component is printed in advance and finally assembled together on site. The advantage is that it solves the limitation of house size, but the disadvantage is that the on-site assembly work becomes labor-intensive and increases the cost.
3. The technology is still immature and has a strong sense of gimmickry. 3D printing is better at printing single small-volume buildings, but today's buildings are developing into skyscrapers, and 3D printing skyscrapers is currently technically impossible. Terry Gou once used mobile phones manufactured by 3D printing as an example, emphasizing that 3D printed parts are useless because electronic components cannot be added to these products and cannot be mass-produced for electronic products. Even if the products are produced, they are difficult to mass-produce and will break when dropped.
Extended information:
3D printing is a branch of rapid prototyping technology. It is a method based on digital model files that uses powdered metal or plastic, fiber A technology that waits for raw materials, then prints them layer by layer, and finally constructs the object. At present, 3D printing technology is developing rapidly, from printing simple toys in the early days to printing human organs, and today it is possible to print houses. (As early as November 2012, Scottish scientists used a 3D printer to print artificial liver tissue from human cells for the first time. In 2019, scientists from a university in Israel even used 3D printing technology to print a "complete" heart).
The 3D printing process is simply divided into three steps: first, computer modeling software modeling, second step, "partitioning" the built three-dimensional model into layer-by-layer sections, and third step, guidance The printer prints layer by layer.
In fact, everyone has seen 3D printed buildings, but they didn’t know that they were 3D printed. For example, in the mass procession celebrating the 70th anniversary of the founding of the People’s Republic of China, the “Endeavor Shanghai” float displayed the site of the National Congress of the Communist Party of China and the Free Trade Zone. , Lujiazui and other miniature architectural models are all manufactured by 3D printing technology.
