It sounds kind of like listenting to music on an old shortwave radio with the bass fading in and out.
Why couldn't you just make the record like they would originally and rotate a disk with a vibrating stylus that cuts the groove into the media?
Since we can transfer files and recordings, the only point of this would be testing higher resolution 3D printing.
I don't expect CD quality sound with this but it's neat that the resolution of 3D printing is improving.
There's a guy in New Zealand with two lathes modified to do exactly that - cut directly to vinyl. He's the only person to actually do that (the old portable lathes still cut lacquer or acetate coated metal discs that can be played a few dozen times before they start wearing out, just like any other conventional lathe). they sound really cool and run about /disc.
There were some old direct to disc booths in the 50s that cut on cardboard discs with some kind of coating, but every disc like that I've found is unplayable - the coating cracks with age.

She can print *my* record.. :)
ahhh I dont know what that even means!!

Pretty neat actually. It sounds really bad and probably fucks up your needle, but its a cool concept.
Retro-piracy. I like it.
People actually used to pirate LPs in the 70s by casting them in alginate and pouring plastic in. It sounded horrible from what I've heard, but much better than this (years ago someone did a DIY demo on a website with recordings - it sounded like a flexidisc).
I'm from Seattle. I wanted to honor that musical legacy by playing our most commercially successful band.
To my knowledge, printers have a tolerance of something like 15 microns, which isn't much for an ordinary object but clearly way too much for a record.
The resolution of a record is something like 1/12 the narrowest dimension of a PVC molecule, and that works out to something like 200 bit digital audio That's all ballpark, someone did the chemistry and math about 5 years ago but I forget the exact figures.
This sounds like s 32kpbs mp3 from the 90s played through broken earbuds.
It sounds like shit, but the concept is still cool. It's one of those "Hey look what we can do!" moments, rather than an issue of usefulness and practicality really.
We've all been able to burn audio CDs with flawlessly duplicated quality for, what, fifteen years now?
"Flawlessly duplicated quality"
a/b them. The error rate is so high on most burned CDs that it's easy to hear a difference between a copy and an original, even on cheap speakers.
There's no redundant data on an audio CD like there is on a CD-Rom so any bits that don't burn correctly are gone. Usually the player's error correction can handle it, but it's audible (especially in the lows, at least to my ear - they lose definition). If the disc is too cheap/burned at a high speed, it can have so many errors that it will skip in cheaper players; even a good burned copy will usually skip easier than a manufactured CD.
Mos tof the claims about CDs being durable/"perfect sound forever" are 100% hype used to market them in North America back in the 80s. In Europe they were more accurately marketed as an upgrade to cassettes, while records were still considered the format of choice for high quality audio since they're more durable and have much higher resolution.
CHOPPED AND SCREWED
I find this very cool. What is that "whistle" that keeps going up and down in the background? They all seem to have it and I'm guessing it's some sort of aliasing issue, since all 3D printing is voxel based AFAIK and if that track is made up of 15 micron cubes, that would probably be audible as a square wave.
Also, she said 4M triangles per minute, which is not much detail at all. Assuming these all came from 44,100Hz CDs, that's 1.5 triangles per stereo sample.
