2. Develop new forming energy sources
Rapid prototyping technologies such as SL, LOM, and SLS mostly use lasers as an energy source, and laser systems (including lasers, coolers, power supplies, and external light paths) are expensive and expensive to maintain, resulting in high cost of molded parts, so many RP research centers Development of new forming energy. At present, there are RP systems that use expensive lasers such as semiconductor lasers and ultraviolet lamps to replace expensive lasers. There are also quite a few systems that use a heated forming material to deposit molded parts without using a laser.
3. Develop molding materials with superior performance
Advances in RP technology have relied on the development of new rapid prototyping materials and the development of new equipment. The development of new RP materials, especially composite materials, such as nanomaterials, heterogeneous materials, and other composite materials that are difficult to fabricate by traditional methods, has become a hot spot in the research of RP forming materials. At present, the research focus of foreign RP technology is the research and development and application of RP forming materials. Most of the scientific and technological personnel who conduct RP technology research in many universities in the United States come from materials and chemical engineering.
Biological science, information science, nanoscience, manufacturing science and management science are the five mainstream sciences of the 21st century. The five major technologies and their related industries will change the world. The intersection of manufacturing science and other sciences is its development trend. Bio-manufacturing with RP and biological sciences, remote manufacturing with information science, and micro-electromechanical systems with nanosciences all provide space for RP technology. Rapid reaction integrated manufacturing system consisting of parallel engineering (CE), virtual technology (VT), rapid tooling (RT), reverse engineering (VR), rapid prototyping (RP), network (Internet, intranet) will be The development of RP provides strong technical support.
