Why choose it

This filament combines the ease of printing of standard PLA with enhanced mechanical properties, making it suitable for parts that need a bit more resilience. The silver colour gives a premium appearance, and the ±0.02 mm diameter tolerance ensures reliable feeding and consistent layer adhesion. With a tensile strength of 50–60 MPa and an elongation at break of at least 50%, prints are both sturdy and slightly flexible, reducing the risk of cracking.

Ideal use cases

• Prototyping and concept models
• Visual display models and architectural mock-ups
• DIY projects and educational use
• Functional parts requiring improved toughness

Good to know

The filament is vacuum-sealed with desiccant to maintain dryness and print quality. It is biodegradable under industrial composting conditions and produces low odour during printing. Store in a cool, dry place when not in use.
