2012年底,我与同事赴美考察了10余个3D打印和社会制造的相关公司,亲身经历使我深感要精确地把握这一新兴行业的现状与随之即来的发展是一项困难的任务。因此,在这里我只能回顾历史,展望未来,抛砖引玉。200多年前,瓦特发明了蒸汽机,拉开了近代工业革命的序幕。实际上,瓦特只是改进了蒸汽机的设计;在他之前,其他的工程师和科学家都曾制出过各种工业蒸汽机,最早甚至可以追溯到公元一世纪古希腊数学家希罗(Hero of Alexandria)发明的气转球。回顾历史,蒸汽机的真正作用其实不在于
At the end of 2012, my colleagues and I went to the United States to inspect more than 10 related companies in 3D printing and social manufacturing. This experience made me deeply impressed with the difficulty of accurately grasping the status quo in this emerging industry and its subsequent development task. Therefore, here I can only look back on history, look to the future and start a discussion. More than 200 years ago, Watt invented the steam engine and opened the curtain of the modern industrial revolution. In fact, Watt only improved the design of the steam engine; before him, other engineers and scientists had produced various industrial steam engines, even dating back to the invention of the ancient Greek mathematician Hero of Alexandria in the first century AD Turn the ball. Recalling history, the real role of steam engine is not in fact
