1. Industry overview
In recent years, with the continuous breakthroughs in 3D printing technology, 3D printing has been successfully applied in many fields such as aerospace, medical equipment, manufacturing, and the arts of life, and continuous breakthroughs have been made. Many countries regard it as the “third time” The commanding heights of the technological revolution”. 3D printing has also attracted much attention because of its wide application, versatility and value.
3D printing is based on digital model files, splits the three-dimensional geometry into several two-dimensional planes, and processes the three-dimensional data layer by layer according to the three-dimensional data of the printed object, and uses the forming equipment to pile up layers of materials to form the target three-dimensional model. 3D printing technology types include fused deposition (FDM), layered stacking (GLOM), photosensitive resin solid-liquid formation (SLA), selective powder laser sintering (SLS), laser selective melting (SLM), etc. Different from the traditional subtractive manufacturing process, 3D printing technology uses additive manufacturing, which has theoretical all-round manufacturability, short time, low production cost, and can achieve efficient use of raw materials and save energy. In line with modern manufacturing methods.
At present, the business of 3D printing companies can be roughly divided into: equipment manufacturing, printing consumables production, software development and 3D printing services. Among them, equipment manufacturers often have their own consumable development and software development functions. Statistics in 2019 show that the scale of the 3D printing industry reached 11.956 billion US dollars, of which the equipment industry was 5.297 billion US dollars, accounting for 44.3% of the industry scale. According to the forecast of the Prospective Industry Research Institute, under the demand of market demand and industry development, the global 3D printing market is expected to exceed 22 billion US dollars in 2022.
The development of the 3D printing industry is a breakthrough in the application of traditional industries under the promotion of technology. With the continuous development of technology, domestic and foreign countries are optimistic about the development prospects of the 3D printing industry. The development of the 3D printing industry is rising steadily, which will bring a new round of traditional manufacturing innovation.
