Excellent April's fool joke, but man it would be sick if you could actually 3D print your own vinyls.

There was a hackaday where someone did that....but it was terrible audio quality from what I remember. Cool idea though.
It will be much easier with a resin printer but controlling for the microscopic pitch shift that would take place with any amount of shrinkage would probably necessitate a specialty printer.
To say nothing of the fine-tuned resin as well as the curing process. 🤯
Pretty sure a decent resin printer has enough resolution for a record. Not sure about durability though.
I'm not sure how high the resolution is on resin printers, but the tip of a record stylus is maximum 0.001mm in diameter, here are the specs for records, it's some pretty small grooves with very fine detail you need for something that's passable.
In the 70s and 80s there were kids toys which played injection moulded plastic discs with a stylus that tracked the groove. I think you might be able to achieve something similar out of a printed record if it was spun fast enough but it wouldn't sound great.
What about modding a printer with a needle to play records? Could that be done?
I get that it's a joke, but can anyone eli5 why this wouldn't work with modern resin printing resolutions?
It works. This was 11 years ago: https://www.youtube.com/watch?v=IQi8FUsZ8OY
For FDM sound quality is horrible but works too.
somewhere there is a script (github?) that generates the gcode files (somebody might reply with link to it).

Turntable uses needle to feel the “bumps” and turn it into sound, if the needle can feel dusts (which is why people always wipe them before playing), it can definitely feel the layer lines.
Dusts are like what single digit microns? while the best resolution for resin printer is at 10 microns.

As an aside, don't wipe records. While dust is unlikely to damage it, scraping something across the surface can cause scratches which can affect the playback. An air duster is your best bet 👍
Wiping with cleaning solution prevents scratching and gets them squeaky clean.
The grooves are like 0.04mm and the best resin printers are only down to 0.1mm. You could do it, but it probably would sound terrible.
The phrozen sonic 12k claims it can get down to .01 mm layers. I feel like that would have a decent shot. But I could be misinterpreting what that means for resin since I've never used it.
I was bracing for the Rick Roll cover in the songs at the end.
