GreenyHT
PLA filament is still very popular due to its simplicity in printing, but has a relatively low heat resistance, which significantly limits its functional use.

As a result of months of implementation testing, Spectrum has developed a new 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 . Spectrum GreenyHT™
The filament contains no plasticisers and significantly outperforms classic PLA grades in terms of stiffness and hardness.

• Fully biodegradable and compostable in accordance with EN 13432
• Bio-based comes from non-genetically modified sources (GMO-free)
• fulfils the conditions for contact with food (technical data sheet)
• increased functionality in terms of heat resistance
• high rigidity

Spectrum GreenyHT™ filament differs visually from normal PLA due to its roughness.
The irregularity and mattness of the surface results in a matt, rough finish, which conceals individual print layers and improves the visual appearance.
