HOW A RECORD IS
3D PRINTED, HONESTLY
From an audio file to a disc spinning on a turntable. This is the whole process — what has to be prepared, what has to go right, and why it's a craft Kräftsound handles for you.
Before anything is printed
Three things decide whether a printed record plays: a mono, carefully prepared audio file, a groove mesh generated from that audio, and equipment that can hold fine, consistent detail. The equipment matters less than people expect — it's the preparation that decides most outcomes, which is why Kräftsound treats this as a craft rather than a one-click export.
THE FULL PROCESS
- 1
Prepare the audio
The track is summed to mono and shaped so its range sits inside what a groove can carry. Anything outside that range can't survive the groove, so leaving it in only adds distortion.
- 2
Generate the groove geometry
Amplitude becomes lateral displacement; time becomes the spiral. Groove pitch is chosen first — wider pitch means cleaner playback and less runtime per side. A lead-in spiral and a locked run-out groove are added.
- 3
Orient and print with precision
The disc is printed flat, grooves facing up, with no supports. Any tilt turns the groove into a stair-stepped diagonal — the single most common cause of a piece that won't play.
- 4
Cure and finish
Resin pieces are washed and fully cured; every piece is left flat under light weight so it doesn't warp while it settles.
- 5
Deburr, check and ship
The groove entry is cleared and the piece is test-played before it leaves. What arrives at your door is finished and ready — at 45 RPM with a conical stylus and standard tracking force.
HONEST EXPECTATIONS
- Wider groove pitch trades runtime for playback clarity — Kräftsound starts wide.
- A warped disc sounds worse than a characterful one; keeping the piece flat matters more than almost anything else.
- Every piece is test-played before it ships, not assumed to work.
- Printing a recording without permission is still copying it — Kräftsound only works with artists who've placed their music in the catalogue.
COMMON QUESTIONS
Can a 3D printer really print a vinyl record?
It can print a playable record-shaped piece. It is not vinyl — the material is resin or PLA, and the sound is narrower and more characterful than a pressed record. The groove is real, and a normal turntable stylus reads it.
Do I need to print one myself?
No. Kräftsound designs, prints and finishes every sonora professionally and ships it to you. You never receive a print file or need to own a printer.
How much audio fits on a 3D-printed record?
A few minutes per side on a typical disc. Printable groove pitch needs more room than a pressed record, so less audio fits in the same space.
Will it damage my stylus or turntable?
A properly finished piece played at standard tracking force won't damage a stylus, though printed discs are more abrasive than vinyl. Getting a disc properly finished is exactly the part Kräftsound takes care of.

Skip the groove maths
Kräftsound turns a track into a sonora — a co-created sonic art object. You design it, we print it professionally and send it to you. No files, no printer required.
