Higher resolution requires better materials - but most additive 3D printing has a max resolution of a few fractions of millimeters (hundreds of microns). A good record has a groove resolution on the order of single micron units - if not smaller. That's actually quite a ways to go. Even conceptually, it's not easy to deposit and solidify something with single micron precision without a well-regulated chamber, a very precise (and probably slow) nozzle. Even the expensive commercial units still have only sub-mm resolution.
