【编者按】3D打印听起来很炫、很酷、很神奇,是一个颠覆性的概念,但不是未来金属加工技术的全部组成。可以预见的是,机床、刀具等加工设备与手段在相当长阶段内仍会发挥重要的作用,仍然会有创新性的发展,至于向哪个方向发展,如何发展,无疑还是要从用户的实际需求出发。 [Editor’s note] 3D printing sounds cool, cool, amazing, a subversive concept, but not the full make up of future metalworking technology. It is foreseeable that machine tools, knives and other processing equipment and tools will still play an important role in a long period of time, and there will still be an innovative development. As to what direction to develop and how to develop it will undoubtedly depend on the actual needs of users set off.
