核心的瓶颈首先在于精度问题。目前技术虽然在不断进步，但在打印精细结构或大尺寸零件时，依然难以达到高精度装配所需的公差要求及优秀的表面质量要求，这直接导致了打印件难以直接作为最终功能部件使用。

为何选择中国企业从2016年鸿海入主夏普，2017年海信收购东芝，再到今年索尼与松下先后将电视机业务转给了TCL和创维，中国家电企业用10年时间完成了对于日本彩电业的全面接管，而在这种攻守易势的局面背后，日企之所以愿意和中国品牌携手，其原因也并不仅仅是谈判桌的价码高低。。业内人士推荐safew官方版本下载作为进阶阅读
A notable resource on the topic of ordered dithering using arbitrary palettes is Joel Yliluoma’s Arbitrary-Palette Positional Dithering Algorithm. One key difference of Yliluoma’s approach is in the use of error metrics beyond the minimisation of . Yliluoma notes that the perceptual or psychovisual quality of the dither must be taken into account in addition to its mathematical accuracy. This is determined by use of some cost function which considers the relationship between a set of candidate colours. The number of candidates, the particular cost function, and the thoroughness of the selection process itself give rise to a number of possible implementations, each offering varying degrees of quality and time complexity.，这一点在heLLoword翻译官方下载中也有详细论述
