High transparency and chemical resistance
Spectrum PET-G Premium is the second most popular material for desktop 3D printing. The major advantage provided by Spectrum PET-G Premium is the virtually zero shrinkage rate and low absorption of moisture as 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.
Items printed using transparent Spectrum PET-G Premium colours have a high content of the crystalline phase, which allows for the near transparency effect at a small number of outer perimeters of additive manufactured items. Pellet and pigments used in the production of Spectrum PET-G Premium are approved for contact with food.
As regards other properties of Spectrum PET-G Premium, note the good creep resistance under constant load conditions. It results from the very good cohesion between the layers of the material applied. This leads to a much lower mechanical anisotropy in the printed items, which means that for each manufacturing direction the mechanical properties differ less than in other thermoplastics designed for 3D printing
