Product Description

Prusament ASA Signal White 800g (NFC) is a top-of-the-line ASA filament produced directly at Prusa Research. ASA (acrylonitrile styrene acrylate) is considered the true successor to ABS – it offers high temperature resistance up to approximately 93 °C, excellent UV stability, and very good dimensional stability. This makes it ideal for long-term outdoor use and mechanically stressed parts.

The Signal White variant is a bright white, technical shade suitable for functional parts, housings, covers, prototypes, brackets, interior, and exterior parts. The material is wound on a new returnable spool with an NFC tag (OpenPrintTag), which allows compatible printers and applications to read basic information about the material directly from the spool.

Key Features

• Premium ASA filament from Prusa Research – produced in-house, with strict quality control.
• Signal White color – a rich technical shade suitable for functional and design use.
• High temperature resistance (~93 °C) – suitable for thermally stressed parts in interiors and exteriors.
• UV stability and weather resistance – ideal for outdoor use (covers, brackets, signage, equipment parts).
• Excellent mechanical strength and toughness – resists impacts and wear.
• Lower shrinkage than ABS – better dimensional stability and less warping under proper printing conditions.
• Possibility of acetone smoothing – smooth, almost "lacquered" surface (at the cost of losing fine details).
• Easy sanding and post-processing – possibility of surface treatment by wet and dry sanding.
• Soluble in acetone – can be used for gluing parts or joining multiple prints.
• NFC tag (OpenPrintTag) in the spool – transmits information about the material, works offline, independently of the cloud.
• High-quality winding – consistent feeding, minimization of tangling.

Recommended Use

• Outdoor parts: brackets, covers, consoles, garden equipment components, elements for facades or pergolas.
• Automotive & technical applications: wiring holders, sensor housings, technical enclosures, parts in the engine compartment away from direct contact with the exhaust.
• Sport and hobby: bike mounts, mounting elements for equipment, robust fixtures.
• Functional prototypes: mechanically and thermally stressed prototypes where PLA or PETG is not enough.

Tips for Printing with ASA

• Environment: printing in a closed box/enclosure is recommended to limit the warping effect for larger models.
• Ventilation: print in a well-ventilated room – ASA releases vapors during printing that can be unpleasant.
• Bed adhesion: ensure a perfectly clean bed surface (e.g., IPA) and optionally use a suitable adhesive.
• Large models: add a skirt / brim / draft shield to minimize corner lifting.
