Prusa CORE One L PP Spring Steel Sheet – Optimized for Polypropylene 3D Printing

The PP Spring Steel Sheet for Prusa CORE One L is specifically engineered for polypropylene (PP) filament printing, delivering reliable adhesion where standard build plates fall short. Designed for materials like Prusament PP Carbon Fiber Black, this sheet features a specialized surface finish that improves first-layer bonding and supports consistent, high-quality results.

Polypropylene filaments typically struggle to adhere to smooth, textured, or satin sheets. This dedicated PP surface solves that problem, allowing you to print larger PP parts without warping or detachment, often without the need for any separation layer or adhesive.

The sheet features a lightly textured finish, similar to satin sheets, providing a balance between adhesion and surface quality. It is also compatible with PLA, PETG, and TPU, though it is optimized specifically for PP-based materials.

Key Features:

• Engineered for polypropylene (PP) filaments

• Excellent adhesion for materials like Prusament PP Carbon Fiber

• No glue or separation layer required for most PP prints

• Supports larger prints with reduced warping

• Lightly textured surface for consistent results

• Flexible spring steel for easy print removal

Care & Maintenance:

• Clean with IPA as needed

• Do not use acetone; it can damage the surface and reduce performance

Usage Notes:

• Best suited for PP-based materials; other filaments may have reduced adhesion

• Visual imprints or gloss changes may appear over time but do not affect print quality

Warranty:

• Print sheets are consumable items and not covered for normal wear or cosmetic changes

• Only defects present on arrival are covered
