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。
Intel documentation describes the 386's Protection Test Unit as a component that "implements fast testing of complex memory protection functions." It is mostly composed of a PLA (Programmable Logic Array), referred to as Test PLA by Intel, that is physically visible by its regular appearance on the die. This single piece of combinational logic replaces what would otherwise be dozens of multi-cycle conditional branches in the microcode. Instead of testing privilege rules sequentially, the microcode issues a single protection test operation, and the PLA evaluates all applicable rules in parallel, producing a complete decision in one evaluation: continue, fault, or redirect to a gate handler.
