By using high-quality raw materials, a 3D printer filament is created that is particularly easy to process. A state-of-the-art manufacturing process achieves very low production tolerances, resulting in impressive printing results with all FDM 3D printers. Each spool is sealed in a high-quality bag. Made in Switzerland, with low diameter and roundness tolerances, and easy to print. Lightweight Polyactid is a polymer that expands during 3D printing. With active foaming technology, parts can achieve a weight reduction of up to 70%. The material begins to foam at a temperature of around 200°C. As the temperature increases, the expansion effect is enhanced. Maximum expansion is achieved at a printing temperature of approximately 250-260°C. The flow factor can be optimized with the right settings.
