The development status of global 3D printing technology


 3D printing technology can be traced back to the invention of the inkjet printer in 1976. In 1984 Charles Hull applied optical technology to the field of rapid prototyping, which opened the curtain of 3D printing. Since the 1980s, the 3D printing industry has received widespread attention at home and abroad, and various 3D printing technologies have also been applied and developed in many industries. Now it has covered many fields such as manufacturing, medical, academic, aerospace, and military.

According to the characteristics of printing technology, 3D printing can be divided into selective laser melting molding, selective laser sintering molding, laser direct sintering technology, electron beam melting technology, fused deposition molding, selective thermal sintering, three-dimensional lithography, digital light processing , Three-digit printing technology, and cell drawing printing, etc.

 

    At present, the main forming technologies of the 3D printing industry mainly include three-dimensional lithography, three-dimensional light solid molding, PVC plastic hot stamping and laminating, melt extrusion molding, three-dimensional inkjet printing, and digital light processing. Since the development of SLA molding technology in the mid-1980s to the late 1990s, more than a dozen different rapid prototyping technologies have emerged. In addition to the foregoing, there are typically 3DP, SDM, SGC, etc. Among them, the four technologies of SLA, LOM, SLS and FDM are still the mainstream of 3D printing technology.


    According to the data from the "2018-2023 Global 3D Industry Market Outlook and Investment Strategic Planning Analysis Report" of the Prospective Industry Research Institute, the development of 3D printing is heavily dependent on technological progress and breakthroughs. At present, the most popular technology for 3D printing applications in the world is FDM technology. , Accounting for 63.9% of total platform revenue; SLA + DLP technology ranked second with 18.1% of total platform revenue, and SLS technology ranked third, accounting for 11.1% of platform revenue.

 

    The domestic rapid prototyping technology research and development work began in the late 1980s, consistent with the international time point. Up to now, four major research and development centers have been formed: Beihang University, Huazhong University of Science and Technology, Xi’an Jiaotong University, and Tsinghua University. Reach the international first-class standard. The team of Professor Wang Huaming of Beihang University is currently one of the few research institutions in the world that can achieve laser rapid prototyping of titanium alloy load-bearing structural parts for aircraft, and is the only unit that has achieved installation; Professor Shi Yusheng’s team from Huazhong University of Science and Technology developed the world’s largest in 2012 Laser rapid prototyping equipment (1.2x1.2m working surface SLS). The R&D teams of Xi'an Jiaotong University and Tsinghua University have also mastered the key technologies of SLA equipment.


 


       

     My country has only introduced 3D printing technology in recent years. Compared with foreign countries, the gap is very large. It is mainly reflected in the technology and market application. The level of research and development is not high, and the degree of connection with the market is low. At present, it has not produced large economic benefits. Unlike the two major 3D printer companies that have emerged in the United States, 3D Systems and Stratasys, my country's 3D printing technology originated from universities such as Xi'an Jiaotong University, Huazhong University of Science and Technology, and Tsinghua University, and related technology transformation is concentrated in school-run enterprises.

 

    As of 2017, my country's 3D printing technology patent applications totaled 9,907, with 3062 applicants, and the average number of patents was 3.24. In 2016, the number of 3D printing technology patent applications was 3554, accounting for 35.87% of all patents; the number of patent disclosures was 4739, accounting for 48.38% of all patents, a year-on-year increase of 79.78%. Among the disclosed patents of 3D printing technology, there are 340 authorized invention patents, 1,630 utility model patents, 293 appearance patents, and 2,530 invention patents.

 

    However, it should be noted that there are still many problems in my country's 3D printing technology, such as the phenomenon of "low-level duplication", which makes limited investment fail to play a better role, especially in the combination of learning, production, and research, which affects scientific research. Commercialization of results, until industrialization.


 In addition, the business community has insufficient understanding of the importance of 3D printing technology and lacks strong support from enterprises. At present, almost all R&D funds invested in are borne by the state, and enterprises have not played their leading role. For companies that have introduced 3D printing technology and equipment, they have also failed to give full play to their role. Because the current 3D printing technology and equipment are too expensive, the majority of small and medium-sized enterprises rarely get 3D printing technology services.
