Spectrum Filament PET-G premium Deep Black 4.5kg (PETG-dBLACK-4.5-SPEC)

High chemical resistance

Spectrum PET-G Premium is the second most popular material for desktop 3D printing. A major advantage provided by Spectrum PET-G Premium is the virtually zero shrinkage rate and low moisture absorption compared to other thermoplastics used for FDM/FFF 3D printing. Items manufactured with PET-G maintain stable properties over a long life. Spectrum PET-G Premium combines the advantages of PLA and ABS. It also provides nearly trouble-free printing and exceptional adhesion between layers.

Big filament reels - for feeding large printing projects

Items printed using transparent Spectrum PET-G Premium colors have a high content of the crystalline phase, which allows for a near-transparency effect with a small number of outer perimeters on additively manufactured items. The pellets and pigments used in the production of Spectrum PET-G Premium are approved for food contact.

Regarding other properties of Spectrum PET-G Premium, note the good creep resistance under constant load conditions. This results from the very good cohesion between the layers of the applied material. This leads to much lower mechanical anisotropy in the printed items, meaning that for each manufacturing direction, the mechanical properties differ less than in other thermoplastics designed for 3D printing.

The very good mechanical properties of Spectrum PET-G Premium, combined with its chemical resistance, determine the application of this material for the manufacturing of items with relatively high dimensional accuracy and stability of both shape and mechanical properties. Accordingly, these are mainly gear wheels and slide bearings subject to relatively high static loads in an aqueous environment. PET-G is also used to manufacture semi-transparent enclosures and backlit sections of various boards and signs
