RESIN VS PLA
THE MATERIAL BEHIND A SONORA
Two materials, two different characters. This is how Kräftsound thinks about which one suits a piece — not a spec comparison, but a craft decision.
The short answer
Resin is chosen when the clearest, quietest playback is the point — a piece meant to be listened to closely. PLA is chosen when toughness and character matter more — an object meant to be handled, given, and played again and again. Kräftsound makes that call for every sonora; you never have to make that call.
WHERE EACH ONE WINS
Resin
- The finest groove walls and the quietest surface
- Resolves detail the other material simply can't reach
- More delicate — the groove edge needs careful handling
- Chosen when clarity is the whole point of the piece
PLA
- Tougher — built to survive handling and repeat plays
- A touch more surface character woven into the sound
- Rewards the close, careful tuning Kräftsound applies
- Chosen when durability matters as much as the sound


A CRAFT CHOICE, NOT A SPEC SHEET
- A piece meant for close, careful listening leans toward resin.
- A piece meant to travel, be handed to someone, or played often leans toward PLA.
- Every material choice is paired with the finishing — curing, deburring, flattening — that lets it play its best.
- Wood-fill, glitter and metal-fill filaments are avoided entirely — they fight the groove instead of carrying it.
COMMON QUESTIONS
Is resin or PLA better for a sonora?
Neither is simply better — they sound and feel different. Resin gives the cleanest, quietest playback; PLA gives a tougher object with a touch more surface character. Kräftsound chooses the material for each piece based on what it's for.
Can a sonora be made from other materials?
Resin and PLA are the materials Kräftsound has refined for this craft. Other filaments tend to be either too abrasive in the groove or too unstable across a flat disc, so they're not used.
Do sonoras wear out?
Like any physical groove, a sonora changes with repeated play over time. Kräftsound finishes every piece to hold up well to normal handling and listening.
Do I choose the material myself?
You choose the track and shape how your sonora looks. Kräftsound chooses and works the material — resin or PLA — to get the best result for that piece, then prints, finishes and ships it.
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.
