High Durability and Rough Surface PLA is always the most popular choice among FDM users due to its exceptionally easy printing. The downside of conventional PLA-based filaments is their relatively low thermal resistance, often reaching only 50–60 "C for non-crystallized prints, which significantly limits their practical use. As a result of several months of testing and implementation, a new filament Spectrum GreenyHT was developed based on a high-performance biopolymer with a softening temperature up to 100 "C and thermal resistance up to 90 "C. Besides improving thermal properties, the original mechanical properties of the plastic were maintained, so Spectrum GreenyHT contains no plasticizers. Furthermore, it significantly exceeds classic PLA grades in stiffness and hardness. Despite modifications, Spectrum GreenyHT remains fully biodegradable and compostable under industrial conditions defined by EN 13432. Its bio-based content comes from non-GMO sources. The material also meets food contact requirements. Additionally, Spectrum GreenyHT filament visually features a rough surface. The surface irregularity and matte appearance effectively mask layers and significantly increase the aesthetic value of printed models.
