In recent years, 3D printing has found its place in the construction field, but there is still a long way to go before it can shake up the construction industry and completely change the existing construction methods.
The test of 3D printing in the construction industry may start from the garden landscape, and it is expected to develop into intelligent construction of digital + 3D printing.
The application of 3D printing technology in various landscape elements includes garden landscape bridges, urban furniture, park benches, flower boxes, tree pools, isolation belts, side stone enclosures, etc.
Next, let's take a look at the typical applications through specific cases.
Coordinates - Beijing.
The 2022 Beijing Winter Olympics has been over for a while. When we look back at the 3D printing behind the Winter Olympics, we can still think of the "snowflake" landscape decorations in the "Open Winter Olympics" theme flower beds. It is located at the northwest corner of the Xidan Intersection. The raw material is urban solid waste, which is produced by 3D printing technology after many complicated processes.
The surface of the 3D-printed simulated snowflake has a rough and grainy feel, and the largest snowflake has a diameter of 1.7 meters.
Coordinates - Shanghai
During the 14th Five-Year Plan period, Shanghai will focus on building a park city and building a city of thousands of parks. Among them, the pocket parks constructed with city leftovers through planning and design will account for 30% and become a major highlight. According to reports, this year Shanghai will complete the construction and renovation of 80 pocket parks, using 3D printing technology for the first time.
Walking to Yantian Greenland Park, you can see 12 groups of petal-shaped leisure seats and three-dimensional flower beds.
Coincidentally, the Meiling Pocket Park in Putuo District has just been completed and opened recently. The entire pocket park adopts a streamlined style, and a set of leisure seats and flower beds that match it also use 3D printing technology, which optimizes the appearance of the entire green space. curve.
Coordinates-Shenzhen
Shenzhen is known as the "City of Thousands of Gardens", with 1,238 parks enveloping the city, and Shenzhen ranks "No. 1 in China" in terms of the number of parks. If you don't like cookie-cutter parks, you can visit the Shenzhen World Convention and Exhibition Center, where a 3D printing park has been built with a total area of 5,523 square meters.
A park consisting of more than 2,000 pieces of concrete was completed in just two and a half months, and the park's sculptures, benches, flower beds, retaining walls, and curbs were produced using robotic arm 3D printing technology. Specifically, it is printed using a proprietary concrete-based construction material through a system of lightweight modular six-axis robotic arms.
Coordinates - Chengdu
If you have the opportunity to visit Chengdu, you can go to Yimahe Park when you pass by Longquanyi District. There is a "Liuyun Bridge" here, with a total length of 66.8 meters, of which the 3D printed part of the bridge is 21.58 meters long, the widest point is 8 meters, and the highest point is 2.68 meters.
The surface layer of "Liuyun Bridge" is printed with polymer ASA+20% glass fiber custom-made materials. The steel structure skeleton is hidden inside the bridge. The 3D-printed bridge deck and the steel skeleton are superimposed to bear the force, and the load-bearing capacity is similar to that of a general bridge. Steel structure footbridge. Through the construction method of segmented printing and on-site assembly, the printing process of the bridge body took only 35 days and used a total of 12 tons of materials.
To achieve a real landing, 3D printing architecture has taken an important step. When you check in at a certain park, you find that the landscape structures have layers of beautiful lines. Yes, they are 3D printed.
