PLA (Polylactic acid) filament is the most popular filament due to its ease of use. It is produced from starch from the cultivation of corn, sugar cane or other starch-rich vegetables. Filaments made from NatureWorks specialised Ingeo PLA grades for 3D printing deliver properties and performance not found in other raw materials or PLAs.
PETG filament is a variant of the widely used PET polymer, its use in 3D printing is booming due to the fact that the ratio between printing difficulty and mechanical characteristics is very good. It is widely used in industry because it is chemically very stable and has a high impact resistance.
