The very first relevance of the 3D printing technology can be track down to the beginning of the 1980s in Japan. In the year 1981, Hideo Kodama was discovering a way to fabricate prototyping system. He made a layer-by-layer approach to accomplish swift manufacturing of various products. He made a layer by layer approach to accomplish the process of manufacturing. This was done by using a photo sensitive resin which was polymerized by UV light. After a few years, 3 French researchers were also looking to create an instant prototyping machine. Since then the applications of the 3D printing have been applied in various fields such as prosthetics & human, biomedical implants, pharmaceuticals, tailored clothing and construction market. In the current times 3d printing has become one of the remarkable technological innovations. In this blog, we will be reading about application of 3D printing in the construction.
3D printing market in the construction is thriving enormously as it holds numerous benefits as written follows-
1- Time reduction
The traditional construction method takes months of time to get completed. It has been estimated that the large projects take approximately 21% longer time than expected. Moreover, it adds up to approximately 80% cost over the initial budget. On the other hand, 3D printing allows to reduce up to 70% of the time. By using the 3D printing the project can be completed in few hours.
2- More sustainable and cost-effective
The 3D printing technology tells the precise amount of the material to be used to make a structure. This precision allows up to approximately 62% less waste to be generated. Due to this, there will be no ample of purchase of the materials. Subsequently, there will be a reduction in costs of purchasing and storage. By eliminating costs and time, various companies will witness a mounting benefits by utilizing the 3D technology.
3- Flexibility in design
The 3D technology allows the user to personalize the task even before the printing of the actual structure. This eliminates the cumbersome process of making changes.
OSHA which is an acronym for US Occupational Safety and Health Administration published a report about worker safety. It states that approximately 1 in 10 workers on the construction sites gets injuries every year. The primary reason for these injuries are the wrongful contact with the device. Hence, one of the most useful benefit of the 3D printing is that it enhances the safety and health of the workers or employees.
1- Robotic Arm
The printer which are automatically controlled gives the capability for the movement and flexibility. The arm is able to print from various angles.
2- Gantry system
The method of the contouring marks the initiation of 3D printing in the process of construction. This process helps in depositing building material to fabricate the 3D model and develop a large scale structures with the help of a smooth finish on the surface.
The process of the extrusion is the most common 3D printing technique. The technique can be used in all the environment. The method is commonly used for prototyping, modeling, and production applications. Furthermore, the method creates the object by layering material through nozzles places on the robotic arm.
2- Powder Bonding
Other than the contrary method of printing, power bonding utilizes powdered raw material as its one the main components. There are mainly two methods-
A- Powder bed jetting- The first is the characterized by melting dust particles with the help of a laser on the desired object. The coating sheet adds more material for each new layer.
B- Binder Jetting- This method utilizes a print head which deposits a liquid adhesive agent. The liquid binds the particles of the powder together to form each layer. This one allows printing with ultra-level of accuracy and able to handle more complex types of prints.
The autonomous robot sprays the construction of the material under the pressure in the desired shape. The spray method allows to fill up the spaces of the structure with concrete.
The demand for the buildings and is rising day by day. The data published by the World Economic Forum states that 55.1% of human beings resides in the urban areas. The technology was introduced in the United States and currently it is leading in the total number of ongoing projects. The global 3D printing construction market size was valued USD 3.5 million in the year 2020 and it is expected to reach 2000 million by the year 2030.
The market holds innumerable opportunities of growth. Although before investing in the market it is always prudent to know the intricacies of the market. Recently, Research Nester has published a research report which includes detailed analysis of the market.
