High stiffness and temperature resistance
PLA is always the most popular among FDM technology users due to its exceptionally easy printing. A problematic characteristic of common PLA-based filaments is their relatively low thermal resistance, which often reaches 50-60 °C in non-crystallized prints, significantly limiting their functional use.
The result of several months of implementation testing is the new Spectrum GreenyHT™ filament based on a high-performance biopolymer with a softening temperature (VICAT) of up to 100 °C and a heat resistance (HDT B) of up to 90 °C. In addition to improving thermal properties, we also aimed not to deviate from the original mechanical properties of the plastic, which is why the Spectrum GreenyHT filament does not contain plasticizers. In addition, it significantly outperforms traditional types of PLA in terms of stiffness and hardness.
Despite the modifications used, Spectrum GreenyHT™ remains fully biodegradable and compostable under industrial conditions according to the EN 13432 standard. The bio-based material comes from genetically non-modified sources (does not contain GMOs). The material also meets the conditions for food contact (for more information, see the section of the material's technical data sheet dedicated to food contact).
In addition, in the visual sphere, the Spectrum GreenyHT™ filament is characterized by the roughness of the printed surface.
The irregularity and matte finish of the surface effectively mask the layers, significantly enhancing the aesthetic value of the printed models.Spectrum GreenyHT™ is a filament for users who expect easy printing in an edition with enhanced functionality in terms of thermal resistance, high stiffness, and a matte, rough surface.
