輪到中國定規則,這一尖端技術,禁止出口,美國3次求購無功而返

近年来,随着中国的发展速度越来越快,西方国家也在不少技术上宣布对中国实施禁运,但让欧美国家没想到的是,在一项尖端技术上,中国不仅领先全球,同时还禁止出口国外,那么中国究竟垄断了什么技术呢?据了解,中国禁止出口的这种技术,正是最近十分火热的3D打印技术,由中国制造的铸锻一体化机床性能十分先进,为了确保技术不外泄,中国早早就下了出口禁令,就连美国都曾3次求购无功而返,看来在3D打印领域,这次轮到中国来定规则了。

中国在3D打印技术上的领先,可谓是未来步入工业4.0时代的保障,自1984年商用3D打印技术首次亮相以来,该技术就视为能够改变现有制造业的尖端技术,相比传统制造模式,3D打印极大节约了人工成本与制造时间,只需塞入所需原材料,就可在短时间内得到成品,由于其蕴含的巨大商业价值,在短短几年时间里,诸如分层实体制造,熔融沉积成型以及激光烧结等新型3D打印技术先后涌现,直至目前为止,3D打印技术已经是西方国家产业布局的关键性项目。

中国在3D打印技术的起步时间较晚,国内虽然早在1988年就首次开展了3D打印技术的研究,但发展速度十分缓慢,直至2013年才有了追赶国外诸如3D Systems,德国EOS等3D打印巨头公司的实力,尽管起步晚,但中国却后劲十足,在2017年,中国已有500多家3D打印领域的相关企业,产业规模突破了100亿元,随着产业规模的扩大,中国的3D打印技术也随着增长,同样是2017年,中国在3D打印领域的专利申请数已高达7402件,位居全球第一。

而其中有不少专利,都集中于金属材料以及3D打印设备上,例如禁止向外国出口的铸锻一体化机床,在技术上的领先,对于中国的工业发展来说是十分有利的,3D打印能够快速制造出使用钛合金,高强钢等高性能金属的工业产品,即使是在飞机制造领域,这项打印技术也能够帮助生产一些小型的精密部件,例如在国产大飞机C919上所使用的复合钛合金构件,便是由国产激光立体成形3D打印技术生产的。

尽管中国的3D打印技术属于世界一流,但在目前阶段,国内打印技术与西方仍然存在着部分差距,由于国内的3D打印技术发展重心在应用与生产设备上,在一些关键性技术方面,中国仍需依赖外国进口,例如3D打印专用材料,由于国内研发的专用材料较少,3D打印件的成品性能普遍较低,而西方国家目前则已经开始研发新型高分子复合材料,中国在材料领域仍然需要进行技术攻关,才能实现对西方国家的追赶。

总的来说,3D打印技术作为最近30年以内才出现的新型技术,距离大规模工业化运用尚需时日,这也给了中国迎头追赶西方的机遇,尽管在部分技术上与西方仍有差距,但在3D打印产业规模不断增大的情况下,中国追上这部分差距只是迟早的事,在未来的工业4.0时代,中国必然会成为领跑者之一。
