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. 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 resistance, high
dimensional stability, and low shrinkage. Spectrum Premium PCTG filament
combines the most desired properties of Tough PLA and PET-G. PCTG material has
a heat deflection temperature of 76"C, as well as excellent print surface and
higher elasticity. Other advantages include high chemical resistance
of printed models. Elements made using transparent colors
of Spectrum Premium PCTG have greater clarity than their counterparts made
with PET-G. This means that it is possible to achieve a near-
transparent effect with a small number of outer contours.
A heated build chamber is not required for printing.
Key features:
- heat deflection temperature 76"C - higher impact resistance than premium PET-G - greater transparency than premium PET-G (applies to transparent colors) - easy printing, processing, and finishing - chemical resistance - high dimensional accuracy of printed parts - hydrophobic, odorless - excellent print surface
Applications:
- visual and functional prototyping - fit tests - conceptual models - manufacturing tools
Filament specifications:
- filament diameter: 1.75mm/2.85mm - extrusion temperature: 240–270"C - bed temperature: 60–80"C - print speed: 40–110mm/s
