Prusa Research has begun selling the polymer pellets used in Prusament production in small batches. Announced on 13 October 2026, the range covers natural PLA, PETG, ASA and PC Blend in 3.5–4 kg canisters and 12–14 kg bags. It targets direct-pellet workshops and research or teaching labs for which an industrial minimum order of hundreds of kilograms or tonnes is excessive.

The products are verifiably listed in Prusa's store and the company ships them pre-dried in moisture-resistant packaging. 'Ready to use in most cases' remains a vendor claim: transport, storage, repeated opening and polymer sensitivity mean that the user still needs to measure condition or establish it through a controlled process trial.

Four polymers and two pack sizes

PLA and PETG are offered in 4 and 14 kg packs; ASA and PC Blend in 3.5 and 12 kg packs. Launch-time European prices including VAT were respectively €39.99/€129.99, €39.99/€119.99, €49.99/€149.99 and €59.99/€179.99. These are a snapshot. Shipping, tax, waste and usable mass belong in the purchase decision.

Every larger pack lowers list cost per kilogram, but the cheapest kilogram is not necessarily the cheapest accepted part. A partly used bag that absorbs moisture or feeds poorly can create more scrap than the discount saves. Consumption rate and resealable storage are therefore economic variables for short runs.

What 'the same raw material' means

Prusa says it diverts and packages the exact pellets used for Prusament filament. In a public response the company clarified that PLA, PETG and ASA are clear base resins without added modifiers, allowing laboratories to add their own colour or additive, while PC Blend is the complete proprietary mixture with additives. That distinction matters because compounding can change flow, crystallisation, bonding, shrinkage and mechanical performance.

The same base resin does not automatically create a part equivalent to spooled Prusament. Filament extrusion adds homogenisation and thermal history; an FGF screw, heating zones, back pressure and nozzle create another. A filament datasheet is useful background, not direct qualification for pellet printing.

FGF: higher throughput, different process risk

Fused Granular Fabrication bypasses filament production, and Prusa says pellet extruders can deposit several kilograms per hour. Furniture, sculptures, tooling and moulds may benefit from lower feedstock and machine-time costs. High mass flow also magnifies feed variation, heat accumulation, warpage and interlayer-bond variation.

Introduce a new pellet through a mass-flow test followed by representative coupons. Record lot, opening time, storage, measured or justified moisture, screw speed, zone temperatures, mass flow and extrudate geometry. Convenient pack sizes make trials easier; they do not replace validation.

Research, teaching and in-house filament

Natural uncoloured pellets can support small formulation experiments. Prusa names colourants, UV stabilisers, glass fibre and carbon nanotubes, as well as laboratory extrusion of 1.75 or 2.85 mm filament. A lower purchase threshold lets a laboratory compare more formulations within one budget.

Added fillers can introduce exposure, feeding and wear risks. Powder handling, blend homogeneity, screw and nozzle wear, and filament diameter and ovality require their own plan. One printable coupon does not establish long-term stability or safety-critical suitability.

Editorial conclusion

The launch changes procurement rather than polymer chemistry. A 3.5–14 kg pack can cover a meaningful laboratory programme or medium FGF part without forcing industrial inventory. The next useful evidence is lot data, detailed technical documentation, moisture condition and repeatability across different pellet extruders. Until then, 'the material behind Prusament' is valuable provenance—not process qualification.
