PETG Premium – Dark grey – Spectrum

PETG Premium Filament – Dark Grey – Spectrum

High transparency and chemical resistance

Spectrum PET-G Premium is the second most popular material for desktop 3D printing. A major advantage of Spectrum PET-G Premium is its near-zero shrinkage and low moisture absorption compared to other thermoplastics used for FDM/FFF 3D printing. Products manufactured with PET-G retain stable properties over a long lifetime. Spectrum PET-G Premium combines the advantages of PLA and ABS. It also provides virtually seamless printing and exceptional adhesion between layers.

Products printed with Spectrum PET-G Premium transparent inks have a high crystalline phase content, allowing the effect of near-transparency in a small number of outer perimeters of additively manufactured products. The pellets and pigments used in the manufacture of Spectrum PET-G Premium are approved for food contact.

Regarding the other properties of Spectrum PET-G Premium, it should be noted the good creep resistance under constant load conditions. It is due to the very good cohesion between the layers of the applied material. This results in much lower mechanical anisotropy in the printed products, meaning that for each production run, the mechanical properties vary less than with other thermoplastic materials designed for 3D printing.

Key Features:

• high transparency compared to other additive manufacturing materials
• very good mechanical properties in terms of hardness, toughness and impact resistance
• temperature resistance HDT – 69°C
• Vicat softening point – 78°C
• chemical resistance
• high dimensional accuracy
• combines the advantages of PLA and ABS
• exceptional adhesion between layers
• odourless seal

Applications:

• visual and functional prototyping
• fit testing
• conceptual models
• production aids
• production of translucent housings and backlit parts for various boards and signs

The very good mechanical properties of Spectrum PET-G Premium, combined with its chemical resistance, determine the application of this material for the production of products with relatively high dimensional accuracy and stability of both shapes and mechanical properties. Accordingly, these are mainly gears and plain bearings subjected to relatively high static loads in an aqueous environment. PET-G is also used for the manufacture of translucent housings and backlit parts for various boards and signs.
