Prusament PLA Anthracite Grey: problems, parts and running costs
Checked: 2026-10-23
Summary
Owners and reviewers most often cite the premium price versus budget PLA, initial stringing at lower temperatures, and mild moisture sensitivity as the main caveats. Running cost is just the filament itself at about $29.99/kg standard or $23.99/kg promotional, with no subscriptions or lock-in. It is a good buy at or below $23.99 for accuracy- or finish-critical prints, and above $30 it competes with budget PLA for hobby use.
Common problems and fixes
- Initial stringing at lower temperatures — reported in hands-on testing; stabilizes at 215 °C with about 5 mm retraction. [8]
- Moisture sensitivity — PLA is mildly hygroscopic; dry at 45 °C for 4-6 h or 50 °C for 4-8 h if prints show popping or poor surface. [6][10]
- AMS and spool-holder fit — the full-size spool needs an adapter for Bambu AMS, and 2 kg spools may not fit standard holders. [10]
- Color-specific finish caveats — Galaxy Black glitter can highlight ghosting and layer lines and Azure Blue showed uneven color on broad surfaces; Anthracite Grey is a standard non-glitter color and is not affected. [5]
- Galaxy Black clog batch (not applicable) — Czech-made spools produced March 13 to May 13, 2026 had an incorrect mix and clogged; US-made spools were excluded, and this does not apply to Anthracite Grey. [5]
- Refill compatibility — new 900 g coreless refills fit the redesigned October 2025 spool, but older 1 kg cardboard-core refills do not. [5]
Parts and consumables
- 900 g coreless refill (fits redesigned October 2025 spool) — replacement option for the spool; older 1 kg cardboard-core refills do not fit the redesigned spool. [5]
Yearly running cost
The only recurring cost is filament at about $29.99/kg standard or $23.99/kg promotional (Prusa3D, checked 2026-10-23), with no subscriptions or lock-in; drying equipment is optional. Annual spend depends on print volume, so no typical yearly figure is available. Not enough data.
When it is a good buy
Price thresholds: $23.99 promotional at Prusa3D (Black Friday 2026) [2], $29.99 standard at Prusa3D [1][2], and $30 MSRP per Filament Oracle [7]. Above $30 with shipping, compare budget PLA such as Hatchbox or eSUN for hobby and decorative prints [6]. Named alternatives: Hatchbox or eSUN budget PLA when cost matters more than tolerance; Prusament PLA Blend, High Speed or Lightweight when a different formula is needed [5].
