Filament Spectrum Premium PET-G
High transparency and 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 are 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 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.
- high transparency as compared to other materials for additive manufacturing
- very good mechanical properties as regards rigidity, hardness and impact resistance
- temperature resistance HDT - 69°C
- Vicat softening temperature - 78°C
- chemical resistance
- high dimensional accuracy
- combines the advantages of PLA and ABS
- exceptional adhesion between layers
- odour-free printing
- visual and functional prototyping
- fit testing
- concept models
- manufacturing aids
- manufacturing of semi-transparent enclosures and backlit sections of various boards and signs
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 a relatively high dimensional accuracy and stability of both shapes 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
Filament is reeled on the neat, transparent spool. Each spool contains information on the type of material, diameter and recommended printing temperature. Filament is vacuum-packed with a moisture absorber. Whole product packed in the original, folied Spectrum Filaments packaging.
VERIFY YOUR SPOOL – the most precise quality control system on the market
Filament for 3D printers is manufactured by the method of free extrusion, which is one of the most difficult processing techniques by extrusion, due to the particularly large impact of process parameters on product dimensions and material homogenization.
During the production each 1mm of Spectrum Filament is being continuously measured in 2 axis with ±0.8µm accuracy, what allows to obtain a high-quality final product. As a proof of this, Spectrum Filaments has introduced, as one of the few manufacturers in the world, the possibility of presenting online, individually for each manufactured spool:
- the course of diameter on the entire length of the spool,
- mean diameter,
- standard deviation.
Precise survey guarantees that Spectrum Filaments products meet rigorous market requirements.
