WHAT ACTUALLY MATTERS
IN PRINTING A RECORD
A record is a surface-finish problem disguised as a print. This is what genuinely decides whether a groove tracks — and why Kräftsound runs that process professionally rather than leaving it to a reader and a settings sheet.
The rule
Everything in this process is in service of one thing: a clean, consistent groove wall from the lead-in to the run-out. Layer finish and flatness dominate. Material and finishing come next. Nothing else moves the needle, which is exactly why getting it right is a craft rather than a checklist — and why Kräftsound keeps that process in-house instead of asking you to chase it on a printer at home.
THE VARIABLES THAT MATTER
- Layer finish — the groove wall is built up pass by pass, and any inconsistency shows up directly as audible roughness.
- Flatness — a disc that isn't true to the platter turns the groove into a stair-step, which is one of the most common causes of a piece that won't track cleanly.
- Wall geometry — the groove has to hold a shape a conical stylus can actually ride, not just a shape that looks right.
- Material behaviour — some materials resolve a finer wall; others trade a little clarity for durability, and the right call depends on the piece.
- Curing and finishing — deburring, cleaning and flattening after printing matter as much as the print itself.
WHY THIS ISN'T A ONE-CLICK EXPORT
None of the variables above behave in isolation — a material change shifts how flatness has to be managed, and a finishing step that's skipped can undo everything that went right in the print itself. Chasing that balance on a general-purpose printer at home, with no way to verify the result, is where almost every DIY attempt at a playable record falls apart.
Kräftsound runs this whole process on tuned, professional equipment, with every piece checked before it ships. There's no settings file, no profile and no print file handed over — you choose the track and shape how the sonora looks, and Kräftsound makes the physics work.
COMMON QUESTIONS
What's the hardest part of 3D printing a record?
Keeping the groove wall consistent from the centre of the disc to the edge. A print that drifts even slightly — in layer finish, in flatness, in temperature — turns a clean wall into something a stylus reads as noise.
Does the printer itself decide whether a record plays?
Less than people expect. The equipment matters, but tuning, finishing and quality checks decide most outcomes. That's why Kräftsound treats this as a production craft rather than a single export setting.
Can I get the print settings Kräftsound uses?
No. Kräftsound doesn't publish or hand over a settings profile or any print file — the production process is run and refined in-house, and you receive the finished sonora rather than the means to produce one at home.
Does material choice affect how a record sounds?
Yes. Different materials resolve the groove wall differently and hold up differently to repeat play. Kräftsound chooses the material for each piece rather than leaving it to the reader.
Still choosing a material? Read resin vs PLA for 3D-printed records.
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.
