PCTG Premium – Black (Traffic black) – Spectrum

PCTG Premium – Black (Traffic black) – Spectrum

Excellent alternative to PET-G

Spectrum Premium PCTG filament is an excellent alternative to PET-G, which is well known in the 3D printing world. Belonging to the same family of copolyester materials, PCTG filament offers similar printability to PET-G. A very important advantage of Premium PCTG filament is its increased impact strength, high dimensional stability and low shrinkage. Spectrum Premium PCTG filament combines the most desirable features of Tough PLA and PET-G. The PCTG material has a heat distortion temperature of 76°C as well as an excellent printing surface and higher ductility. Additional advantages include the high chemical resistance of the printed patterns.
Elements made with Spectrum Premium PCTG transparent colors have a higher transparency than their counterparts made with PET-G. This means that it is possible to achieve a near-transparency effect with few outer contours.

A heated chamber is not required for printing.
