Excellent alternative to PET-G
Spectrum Premium PCTG
filament is an excellent alternative to PET-G, which is well known in the
world of 3D printing. The PCTG filament, which belongs to the same material group
of copolyesters, offers similarly easy printing as PET-G. A very important
advantage of Premium PCTG filament is its increased impact toughness, high
dimensional stability, and low shrinkage. Spectrum Premium PCTG filament
combines the most desirable properties of Tough PLA and PET-G. The PCTG material has
a heat deflection temperature of 76"C, as well as excellent surface finish and
higher elasticity. Other advantages include high chemical resistance
of printed models. Parts made using transparent Spectrum Premium PCTG colors
have greater clarity than their counterparts made using PET-G. This means that a near-
transparency effect can be achieved with a small number of outer contours.
No heated build chamber is required for printing.
Key features:
- heat deflection temperature of 76"C- higher impact toughness than premium PET-G- higher transparency than premium PET-G (applies to transparent colors)- easy printing, processing, and post-processing- chemical resistance- high dimensional accuracy of printed parts- hydrophobic, odorless- excellent surface finish
Applications:
- visual and functional prototyping- fit testing- conceptual models- manufacturing tools
Filament specifications:
- filament diameter: 1.75mm / 2.85mm- extrusion temperature: 240–270"C- bed temperature: 60–80"C- printing speed: 40–110mm/s
