As a frontier and subversive technology, 3D printing has a wide range of unexpected uses. Nowadays, many countries in the world give strong support to the development of 3D printing industry in terms of funds and policies, and even upgrade the 3D printing industry to a national strategic level. With the joint advocacy and vigorous promotion of many countries, the research and development of 3D printing frontier technology has been accelerating, and hot applications have emerged.Recently, the President of Sierra Leone, Julius Maada Bio, attended the Fourth Industrial Revolution Conference in Uganda. As an advocate of innovation in science, technology and governance, he delivered a keynote speech on the application of 3D printing technology.President of Sierra Leone Julius Motor Bio 1Ender-3 Pro for New Application of Sierra Leone's National PolicyDuring a lunch in the state legislature, senior government officials were discussing the educational situation within the country. Without visual and intuitive data, it was difficult for the people present to participate fully in the discussion. At this time, Biot is trying to make the existing complex data into intuitive and effective data, can clearly understand the reality of the problems facing the Ministry of Education.Later, the State Council's Bureau of Science, Technology and Innovation (DSTI) immediately began to calculate the distribution of girls outside school in each place, and used a 3D printer to create a map model that accurately identifies the results of the analysis. Through this 3-D printing model, government officials can see the education data of different cities from different perspectives, so that people can see at a glance the distribution status of off-campus girls and the problems and challenges they will face.3D Map of Sierra LeoneDescribe the distribution of girls who do not attend primary schools throughout the countryBio also used a 3-D printer to create a data model of the distance children walk to school. Using this 3-D print model, he discussed with government officials how buses should be distributed nationwide. The 3-D model also provided further analysis and reference for the ideal location of a new school.In other data-driven policy dialogues, Bio also uses a 3D printing model, which greatly improves the speed and quality of local strategic decision-making. There is a desktop-level 3D printer on the desk of Bio's office. This machine is Ender-3 Pro independently developed by Shenzhen Chuangxiang 3D Technology Co., Ltd.Ender-3 Pro, which was launched in March 2018, has now shipped more than 200,000 units abroad. In just a few months after its launch, it has formed a huge user base at home and abroad. Google's global search list for 3D printers has rapidly climbed to the top of the list, becoming the next CR-10 (YouTube has more than 10 million videos and a single viewing volume has reached). Hundreds of thousands of times) and then another hot global item.Biao also said in an interview that this is their first 3D printer and that in the future they will keep pace with the times, install more 3D printers and print various data models to help them formulate appropriate policies and promote Sierra Leone's development.Bio's desk has an imaginary three-dimensional Ender-3 Pro 3D printerAs the representative of "Internet + Intelligent Manufacturing", 3D printing technology is widely used in aerospace, medical, clothing, education, industrial design, culture and art, military, film and television, household appliances, light industry, archaeology, sculpture, jewelry and other fields. From parts to automobiles and airplanes, from animated characters to buildings, from fingerprint gloves to heart models, can be produced by 3D printing.According to the relevant data analysis, with the background of industrial 4.0 and the strong support of governments, it is expected that the global 3D printing industry will be in a period of rapid growth in the next decade. As a vigorous promoter of the global 3D printing industry, China will devote more energy to the training of 3D printing professionals, the formulation of industry standards, and the research and development of cutting-edge technologies.As a preacher of 3D printing industry, Creative 3D will never forget its original intention and move forward, unswervingly follow the line of internationalization and scientificalization, steadfastly increase R&D investment in product innovation, and take part in competition and cooperation with the global market, so as to establish a new trend for the development of China's high-end manufacturing industry and promote the development of 3D printing industry.
