Not Likely to Result in a high quality record.

The signals that are way down in level on a vinyl record are so small, they approach the wavelengths of light.

The highest resolution 3-D printer I am aware of has a minimum feature resolution of 0.1 mm or so. We could be generous and say that a super-duper pro grade 3-D printer might be able someday to reach 0.01 mm feature resolution. Still way off of -60 or 70 dB signal levels on a vinyl record groove. The 0.1 mm might represent something like -10 to -12 dB level in a groove, if even that low, or the equivalent of a broken Sound Blaster sound card operating at only 2-3 bits of resolution.

The signal levels and their physical size in the groove were discussed in the following articles:

Popular Electronics, Nov. 1980 issue, "Phonograph Playback: It's better than you think!" By Dr. Bruce Maier and Jon Risch

Audio magazine, March 1981, page 21, "More Than One
VTA", again by Dr. Maier and myself.
