Prusa CORE One L Satin Powder-Coated Print Sheet — The All-Rounder for Large Format

The Prusa Satin Powder-Coated Print Sheet for the CORE One L brings the same excellent all-round adhesion properties of the standard CORE One satin sheet to the larger 300 × 300 mm build platform. A lightly textured matte finish provides optimal adhesion across the widest range of filament types without glue, Windex, or any other adhesion aids for most materials.

The double-sided spring steel design snaps onto the CORE One L’s magnetic build plate and flexes for easy print removal. Both sides feature the same satin powder-coated surface.

Why Satin for the CORE One L?

On a large-format printer, bed adhesion is even more critical than on smaller machines. Larger prints have more surface area pulling against the bed during cooling, and corner lifting on a 300 mm print can ruin hours of work. The satin surface provides strong, consistent adhesion across the full build area without the complications of glue stick application on a large plate — no uneven adhesion zones, no dried glue patches, no cleaning 300 × 300 mm of glue residue between prints.

Best Sheet for Polycarbonate

Polycarbonate prints better on the satin sheet than on either smooth or textured options. For frequent PC printing, a thin glue stick layer is recommended to protect the sheet surface — but adhesion is excellent without it.

Compatible Materials

PLA — excellent adhesion, no glue needed
PETG — excellent adhesion, no Windex or glue needed
ABS & ASA — good adhesion in enclosed chamber
TPU / FlexFill 98A — good adhesion, no glue needed
Polycarbonate — best of any Prusa sheet, glue recommended for frequent PC use
PA / Nylon — with appropriate settings

Care & Maintenance

Clean with soap and warm water, or isopropyl alcohol (IPA) for routine maintenance. NEVER use acetone on the satin sheet. Acetone creates microfractures in the powder coating that degrade the surface over time. Do not use sharp metal scrapers — flex the spring steel to release prints.

Compatibility

This sheet is sized for the Prusa CORE One L only. It does not fit the standard CORE One, CORE One+, MK3, or MK4 — those use a smaller sheet size.
