The Advantages of 3D Printing in the Use of Construction Technology

(1) 3D printing technology can reduce construction costs

The use of 3D printing technology only requires designers to complete the manufacture of architectural models through computers and printers, which greatly reduces the use of labor and saves labor costs. The customization of modules and the small batch production of single pieces reduce the production cost and the cycle of construction projects, and can also save a lot of construction raw materials, so the cost of construction projects has dropped significantly.

(2) 3D printing can shorten the construction period

3D printing technology neither uses traditional construction teams nor traditional building materials such as bricks and tiles. Most building components can be printed and constructed in factories, and then assembled on site, which greatly reduces the production cycle of construction projects. , The production efficiency is greatly improved. Practice has shown that compared with traditional buildings, 3D printing technology is more than 10 times faster, does not require molds, can effectively save costs, is environmentally friendly, green, and low-carbon, effectively improves construction production efficiency, and can promote Development and transformation of the construction industry.

(3) 3D printing technology can improve the quality of construction projects

3D printing products are seamlessly connected, with stable performance and connection strength unmatched by traditional buildings; the participation of computer programs and digital technology ensures the accuracy of building data; the use of strong building materials ensures the quality of the house, the penetration of the house leakage, cracking and other problems can be improved to a certain extent.

(4) 3D printing technology can reduce the operational risks of construction projects

The use of 3D printing technology can reduce the risk of falling from heights and building collapses in construction operations, and provide workers with a safer working environment.

The application of 3D printing technology in the field of architecture also has many other advantages. For example, 3D printing technology can print various complex and personalized architectural shapes according to the drawings of architects, and it is beautiful and environmentally friendly. For another example, 3D printing technology can shorten the construction period, realize the rapid construction of architectural models, and solve the problem of population living quickly and at low cost.



The disadvantages of 3D printing technology

3D printing technology is a technological change in the construction field, but the application of 3D printing technology is still in the exploratory period, and there are still many practical problems to be solved.

3D printing technology mostly uses construction waste, industrial waste, cement, steel bars, etc. as raw materials for printing buildings. Although these materials have good compression resistance, their tensile strength is relatively poor. Printing materials with good compression, tensile and crack resistance and high initial setting strength are the development trend of 3D printing in building materials.

Before the 3D printed building structure reaches the strength standard specified by the design, the printing material needs to solve the support problem of the building structure. Complex 3D printed components have a lot of weight. If it takes a long time to reach the strength standard, the 3D printed architectural model may be deformed.
After 3D printing technology completes the printing of the architectural model, follow-up work such as grinding, cutting, and assembly of the architectural model is required. There are still practical problems in how to level the wall.

In conclusion

3D printing technology is not only fast, low-cost, and exquisite in shape, but also more environmentally friendly and more in line with the needs of modern society. In addition, it also plays a certain role in improving the quality of houses and reducing operational risks. But the fly in the ointment is that 3D printing technology is not yet mature, and it is lacking in tensile strength and deformation resistance. However, I believe that in time, 3D printing technology will definitely become a trend in the construction field.

 The application of 3D printing technology can be traced back to the stereolithography (SLA) technology developed by Charles Hull of the United States in 1986. In the next 20 years, a number of 3D printing technology patents such as layered solid manufacturing (LOM) and fused deposition modeling (FDM) came out one after another. , SLM solution, etc.  Since 3D printing technology started earlier in European and American countries, after more than 30 years of development, technologies such as SLA (stereolithography) and SLS (selective laser sintering) have been relatively mature. It is relatively perfect in R&D and manufacturing of high-temperature metal materials and equipment. The development status of 3D printing technology Since the beginning of the 21st century, various subdivisions of additive manufacturing technology have been further developed, such as digital light processing (DLP), multi-head jet technology (PloyJet), etc. have been developed. Special 3D printing ...

What is 3D Printing？ 3D printing is a method of additive manufacturing, which can process objects layer by layer according to 3D model files. 3D printing can ignore the complex structure of the model, and print out the model, which can be well personalized and customized. Production. The molding method of 3D printing is very suitable for the production of toy models. Magic Box will introduce to you the main advantages of 3D printing toy models  . The general process of 3D printing toy models is conception → manual drawing of floor plans → computer software drawing of 3D modeling → 3D printing → re-verification. After several iterations, the design is finally completed, and 3D printing generally only takes one day to complete, which can greatly reduce production time. The Main Advantages Of 3D Printing Toys: (1) Personalization of toys is easier: because of 3D printing, customization or highly personalization of toys is already very easy to achieve. (2) Development of new toy produ...

With the development of society, there are always some new technologies appearing in our lives and playing an increasingly important role. The 3D printing we are going to talk about today is such a technology. 3D printing has only appeared for decades, but its development is visible. Many people may mention that the first thing that pops up in the mind of 3D is 3D movies watched in cinemas, which is indeed a kind of 3D technology. application, but today we are talking about 3D printing, a technology that is more widely used in our lives and has changed our lives the most. 3D is now widely used in many fields such as manufacturing, medical treatment, education, aerospace, military and so on. Since the birth of 3D printing technology in the 1980s, it has been considered as a rapid prototyping technology for a long period of development, but in the past five to ten years, the application field of 3D printing technology has gone beyond the prototype Instead, it has gradually evolved toward...
