5. Research new forming methods and processes

On the basis of the existing, expand the application of RP technology and explore new forming technologies. New forming methods emerge in an endless stream, such as three-dimensional microstructure manufacturing, engineering of bioactive structures, laser three-dimensional internal cutting technology, and layer exposure methods. The research on RP micro-manufacturing mainly focuses on the mechanism and method of RP micro-forming, the precision control of RP system, the control of laser spot size and the forming characteristics of materials.


The micro-parts currently produced are only conceptual models and cannot be called functional parts, let alone microelectromechanical systems (MEMS). To achieve MEMS, there are still many problems to be overcome. For example, as the size decreases, the ratio of surface area to volume increases, surface mechanics and surface physical effects will play a leading role; micro-tribology, micro-thermodynamics, micro-system design, Manufacturing, testing, etc.


Arc spray forming is an important metal rapid prototyping technology that has recently been developed. Laser powder rapid prototyping technology, also known as Laser Direct Metal Rapid Prototyping and Manufacturing (LDMRPM), is one of the most important goals of rapid prototyping technology. It can directly or indirectly manufacture metal with full function. Parts and molds have become an inevitable trend in the development of rapid prototyping technology.
