Is anyone working on a reasonably priced turntable to play vinyl discs without degrading them? In the mid '80s, Finial Technology announced such a turntable, and had a working unit at CES in 1986. It had a stylus that contained laser interferometers that could very accurately and precisely measure the distance from the stylus to the grove walls. It kept the stylus near, but not touching, the groove, getting the audio…
I remember reading an article about somebody 3D-printing vinyls a couple of years ago. It sort-of worked but it wasn't quite there yet. Still, 3D printing technologies improves very fast nowadays so maybe in the not-so-far future it'll make more sense to just print a new vinyl from the master the current one is too badly damaged rather than spend money on a super expensive turntable? In either case I feel like it's s…
We have the technology to 3d print records, though the audio-fidelity maybe isn't there (~2 years ago) for music more subtle sounds (jazz or classical). It also did not seem possible on an (affordable) FDM 3d printer and I didn't have access to an SLA 3d printer.
Keep in mind prints would take hours to do, on top of the usual delicateness of 3d printing.
Part of the joy of having a record is the rest of it, the album cover, the notes, etc. I wasn't trying to copy an existing record, so for me there was considerable effort required for those parts as well which made it harder to justify the extra effort 3d printing a record would have required.
Which brings me to my last point. There are numerous services that will accept a digital audio file and mail a physical record, in the $200-500 range (length/size dependent). Depending on your budget (esp compared to gaining access to an SLA printer and your time), that may be more effective.
