Innovation and practice: 3D printing expert Ma Yihe

On March 29, Yingchuang announced at an architectural 3D printing press conference held in Yifu building of Tongji university that the company has a 6.6-meter high, 10-meter wide and 150-meter long 3D printer in Suzhou factory area, which can print out 10 concrete bungalows of 200 square meters in 24 hours. The habitable rooms are on display in a vacant lot in Shanghai's Zhangjiang high-tech Qingpu industrial park.

　　News just came out, the domestic 3D printing world suddenly boiling. Previously, 3D printing houses have been introduced in developed countries. But the material is either plastic or cement, and is not built as fast as innolux and has never seen a 3D printer as big as innolux claims.

　　Ma Yihe proudly told Xinmin News: Yingchuang, which has been producing green building materials for 12 years, can print an entire house in 3D continuously, whether low or high. Moreover, 3D printing "ink" is the reuse of construction waste, including industrial waste, tailings, etc., which not only reduces the construction cost, but also reduces the damage to the environment.

　　Yingchuang did not release details of its own 3D printers because of trade secrets. If what he said is true, China's 3D printing hybrid cement technology is the world's leading technology, and rapid printing of green buildings is no longer a dream.

　　The announcement came five days after U.S. President barack Obama paid a special visit to the Dutch national museum during a nuclear security summit of 53 leaders in the Netherlands. He watched a full-size, proportionate model of the ongoing 3D printed canal house project.

　The Amsterdam in the Netherlands DUS architects from the beginning of the company, by a 3.5 m high of 3 d printers to produce plastic building components, plans to complete the set up 13 rooms in a building made of amorous feelings of the canal houses in Holland. It took the Dutch three weeks to print a wall three metres high. The internal frame of the building has also been printed out, and space for power lines and water pipes has been reserved. It is estimated that it will take three years for the entire building to be completed. It is worth noting that the materials used for printing are transparent plastic and wood fiber mixtures made from environmentally friendly recyclable materials. To make the structure strong, the building is filled with lightweight cement.

　　Mr. Ma said: “ The house was plastic, not a real building at all, and they started off in the wrong direction. President Obama will be surprised if he visits our results.” Xinmin reporters saw that the front desk and conference room tables were 3D printed products with the appearance and feel of ordinary cement.

　　The core of intra 3D printing is ink, nozzle and supply system, said Ma. As the "ink", its core technology is based on high quality cement and glass fiber is given priority to, rely on independent research and development of printer equipment linear continuous extrusion type printing, and traditional architecture, even stronger than traditional strength of the steel construction; Hollow walls not only greatly reduce the weight of the building itself, but also enable builders to fill the insulation materials in its empty "abdomen", making it a whole self-insulation wall. Through different requirements, can be arbitrary wall structure design, the reserved "beam" and "column" casting the space, one-time solve the bearing structure of the wall, so as to make it play an important role in the high-rise building.

　　The reporter saw a section of video on Ma's mobile phone. It is said that the printing process of 3D printer nozzle in Suzhou factory is only a partial lens. Reporters did not see "the world's largest 3D printer," nor could they tell the speed of the material being printed. But the video image is very similar to the Contour Crafting 3D printing technology photo released by the university of southern California in January.

　　Thanks to funding from NASA, contouring can now print about 232 square metres of two-storey buildings in 24 hours. As early as the summer of 2012, the director of the contouring process program, professor biherlock belloch of the university of southern California, and a professor at the university of southern California. "Behrokh Khoshnevis said: “ Technological" printed wall is hollow, though the lighter, but their intensity coefficient is higher than traditional houses, but also save 20% - 25% of the funds, 25% to 30% from 45% to 55% of the materials and artificial.” Now, NASA hopes the technology will allow humans to take local materials, quickly and in bulk print "alien houses" after migrating to the moon or Mars.

　　President Ma said: Prof hoshnevis, who visited China last year to contact intronics, left with an "ink" cement as a souvenir. It is unclear whether the contouring process and intra are related, since the professor himself has not been contacted.

Architectural revolution

President Ma said: He started his business in Shanghai in 2002 and has been focusing on building materials. Intron 3D printing technology can be said to be the result of 12 years' hard work of him and his team. It is a hard startup time. Light steel keel and gypsum board is a kind of traditional building materials product, with low technology content and economic added value .

　　While making the product, Mr. Ma learned from foreign literature about GRG, a new decorative industrial material, and quietly began research and development. In the summer of 2004, they explored the formula and production process of GRG and successfully entered the project of Shanghai Oriental art center. Since then, yingchuang has undertaken hundreds of projects, accounting for more than 95% of the market share of China's theater GRG project.

　　Ma Yihe team also developed a new type of ecological stone SRC (special glass fiber reinforced composite cement), applied in Hainan international conference and exhibition center, Shanghai Sheshan tea garden villas on construction projects. The company has since made breakthroughs in FRP and indra. It is these technologies that lay a good foundation for Yingchuang 3D printing.

　　In 2008, Yingchuang has printed the first building wall material with 3D printing technology. Ma said that Yingchuang has developed 3D printer equipment independently, printing oil and printing technology during 12 years. The company has 77 national patents, 400 successful case, which not only solves the problem of irregular decoration and decoration in large buildings (especially theaters and sports venues), but also saves a lot of costs for owners.

　　It is worth mentioning that the "ink" of Yingchuang 3D printing buildings is the reuse of construction waste. In Xiangyang, Tianjing, Shanghai and Suzhou, it can basically digest the local construction waste nearby at present.

　　Ma hopes to build 100 "dream factories" across the country in the future -- local materials, recycled construction waste, industrial waste and tailings, and processed, processed and separated by technology, making it the raw materials of 3D printing “ink”.
