Prusament Premium PLA: problems, parts and running costs
Checked: 2026-10-25
Summary
Prusament Premium PLA is a polychromatic PLA filament whose Mystic colors shift with nozzle temperature, layer height and viewing angle, on the same base resin as standard Prusament PLA. Known issues are brittleness, low temperature resistance, lack of independent test data, and high shipping costs from Prague. Ownership cost is replacement spools at about $23.99 sale, $29.99 list, or $35.99 at a US retailer, with refill spools at about $26.99 for some colors.
Common problems and fixes
- Brittle material — PLA has average toughness and is brittle; not suited to load-bearing or impact parts; Prusa recommends more perimeters rather than higher infill for strength. [1][3]
- Low temperature resistance — temperature resistance is 55 °C and parts soften above about 60 °C, so it is unsuited to outdoor or warm environments. [1][3]
- No independent test data — no independent instrumented test was found; evidence is manufacturer specifications and in-house tests, and per-spool QR-code diameter data is manufacturer-generated and not independently verified. [4][5]
- High shipping costs — manufacturer blog comments mention high shipping costs from Prague. [4]
- Not for repeated food contact — 3D-printed PLA parts are not recommended for repeated food contact because layer grooves can harbor bacteria; a food-safe coating is suggested. [1][3]
- Industrial composting only — PLA is biodegradable only in specialized composting facilities above 80 °C, not in home compost. [3]
Parts and consumables
- Replacement filament spool — standard spools at about $23.99 sale / $29.99 list (Prusa) or $35.99 (Printed Solid); refill spools at about $26.99 for some colors. [1][2][7]
Yearly running cost
No subscription or lock-in; cost is replacement spools at about $23.99 sale, $29.99 list, or $35.99 at a US retailer, with refill spools at about $26.99 for some colors. Not enough data for a typical annual total.
When it is a good buy
Price thresholds: at $23.99 or less strong value; $26-$32 fair; above $32 weak unless the Mystic effect is wanted. Alternatives: standard Prusament PLA for the same base resin without the Mystic effect; Prusament rPLA, blends, PETG, ASA, PC or PA for different properties; Prusa Basic PLA (externally made) for lower cost. Buy Prusament Premium PLA when verified ±0.02 mm tolerance and per-spool traceability matter or the Mystic finish is wanted.
