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. 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 sizes. A heated bed is advantageous for PLA filament, but not strictly necessary. We recommend using a cooling fan when processing PLA filament. Furthermore, PLA is characterized by significantly more pleasant odor properties compared to other plastics.
