| John O. Milewski, a pioneer of metal additive manufacturing, analyzed 3D in his new book, Metal Additive Manufacturing: Rocket Jet, Medical Implants and Custom Jewelry. The future of printing trends, metal additive manufacturing applications will be popular.  GKN Aerospace Reinforces and Connects Vulcan 2 Nozzle Parts with Wire Laser Additive Manufacturing One can look at the future of 3D printing from two perspectives, one is the evolution of specific technologies driven by specific needs over the past 30 years and the other is an exciting new direction driven by global trends, technology convergence and personal creativity. In the next five years, additive manufacturing will make metals more popular. Twenty years ago, 3D metal-based 3D printing and additive manufacturing (AM) originated in rapid prototyping. John was working in a team working on the melting of 3D metal-shaped laser powders, dreaming of aerospace components, medical implants And a wide range of industrial applications, engineering challenges such as laser, metal powder technology, process speed, accuracy, distortion, residual stress and surface finish are seen as widely adopted barriers.In addition, computer modeling, software, hardware, laser and process control technologies Limitations and costs are huge, so John and the team have speculated that it will take at least 10 years for the metal to enter mainstream manufacturing. Ten years ago, metal additive manufacturing was not a mainstream technology and the unremitting efforts in science and engineering contributed to the continuous development of the fundamental industrial application of core technologies.However, 3D printing prototypes using polymers have reached the mainstream of use, made of special metals Complex shape demo hardware is produced. Nowadays, the dream of 20 years ago has come true, and additive manufacturing parts are finally used in key aerospace, medical and industrial applications. In more and more critical applications, applications have crossed the finish line for certification Use, thus providing a variety of similar product development direction.An additive manufacturing standards (such as ASTM developed standards) will be widely used in the industry by NASA to build and test the rocket nozzle manufacturing additive, Setting the track for formal standards to bring human hopes and dreams out of the earth Additive manufacturing medical devices such as Stryker's titanium alloy spinal implants are applying for FDA certification and integrating additive manufacturing technology Humans can benefit from it.
The future of metal additive manufacturing will not only continue these core directions, but will also accelerate and prosper with advances in software, hardware, artificial intelligence, information technology, robotics, machine learning, sensors and industrial internet of things. The continuous unification and diversification of basic technologies make it reasonable to predict the exponential growth of the scope and speed of metal additive manufacturing. Desktop-grade 3D printers are becoming more widely used, with 3D printing available for educational programs, small businesses, individuals, inventors and hobbyists, etc. The trend for low-cost materials and systems over the next five years is Is about to enter the metal field, to achieve the true popularity of metal printing. |
