Description
Technical field
The present invention relates to a kind of ELUTION METHOD of powder, and in particular to a kind of that 3D printing material elute to obtain nodularization
The high powder body material of rate.
Background technology
3D printing technique is the focus studied in currently advanced manufacture field, belongs to multi-crossed disciplines convergence and science and technology wound
Newly, the characteristics of green manufacturing, intelligence manufacture and socialization are manufactured is embodied.Its achievement in research has been widely used in consumption electricity
The fields such as son, automobile, Aero-Space, mould, defence and military, industrial design, regenerative medicine.European and American developed countries pay much attention to,
Think that 3D printing technique will promote third time industry to remove from office together with other Digitized Manufacturing Technologies such as network technology, robot technology
Life.Various countries have also carried out corresponding layout and policy guide, such as China《National medium ＆ long term sci-tech development program outline
(2006-2020)》、《National " 12 " scientific and technological development planning》, and the U.S.《The advanced manufacturing strategy meter of country
Draw》Deng.Extensive use of the 3D printing technique in industry manufacture field is realized, also needs to solve the problems, such as a series of technical bottleneck,
Such as 3D printing precision and efficiency, printed material, printed design and printing equipment problem.
The material of current 3D printing is mainly solution based on metal, polymer and composite, it is thread, bar-shaped and
Powder body material.In terms of material, the restriction wide variety of maximum bottleneck problem of 3D printing technique is the material category for being adapted to printing
Less, expensive, shortage feature.Therefore, for the technical need in different application field, 3D printing material rational design is studied
Principle and method, develop feature printed material technology of preparing, realize the prepare with scale of printed material, and not only development is printed
