From ancient times to the present, human curiosity about the universe has never stopped, and has been walking on the road of exploration.
At 18:00:00 on May 5, 2020, the Long March 5B, carrying a new-generation manned spacecraft test ship and a flexible inflatable cargo return capsule, blasted off from Wenchang Space Launch site, marking another big step forward in China’s manned spacecraft testing. It is reported that the new generation of manned spacecraft is carrying a “composite space 3D printing system” independently developed by China, which is the first 3D printing experiment in space in China and the first 3D printing experiment of continuous fiber reinforced composite materials in space in the world.
As we all know, the presentation of 3D printing products is inseparable from 3D printing technology, system, and 3D printing materials. In fact, with the continuous expansion of the application field of 3D printing technology and the increasing variety of 3D materials, the global 3D printing materials industry has developed rapidly. In 2018, the global 3D printing materials industry market size reached $3.227 billion, a year-on-year growth of 20%.
In general, 3D printing material types can be classified in different ways. According to the chemical properties, 3D printing materials can be divided into composite materials, metal materials, ceramic materials, polymer materials; according to the physical state, 3D printing materials can be divided into filamentous materials, liquid materials, powder materials and thin sections. In terms of the types of 3D printing materials in China, titanium alloy, PLA and nylon accounted for a relatively high proportion, followed by aluminum alloy, stainless steel, resin and other materials accounted for a relatively low proportion.
