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。

This approach shares a lot in common with the idea of multivariate interpolation over scattered data. Multivariate interpolation attempts to estimate values at unknown points within an existing data set and is often used in fields such as geostatistics or for geophysical analysis like elevation modelling. We can think of our colour palette as the set of variables we want to interpolate from, and our input colour as the unknown we’re trying to estimate. We can borrow some ideas from multivariate interpolation to develop more effective dithering algorithms.
But a robot vacuum is the only kind of device that regularly roves around your home. That gives this vulnerability a unique sense of foreboding, perhaps enough to provide the plot to a found footage horror film.
