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, easy to print. Polylactic acid is a polymer that consists, among other things, of lactic acid molecules. Currently, we offer PLA filament in 1.75 mm and 2.85 mm. A heated bed is advantageous for PLA filament but not strictly necessary. We recommend using an air cooler when processing PLA filament. Furthermore, PLA is characterized by significantly more pleasant odor properties compared to other plastics.
