The R3D PETG-Silk Lead Gray Filament combines the proven properties of PETG with an elegant silk-gloss finish. This filament is suitable for use in standard FDM 3D printers and produces printed objects with a glossy, silky-shimmering surface in a subtle lead gray tone. PETG-Silk combines good impact resistance with high layer adhesion and moderate flexibility. The material has a low moisture absorption of 0.4%, which positively influences storage stability and print quality. The tight diameter tolerance of ±0.02 mm ensures uniform material feed and consistent print results. The filament is compatible with AMS systems and can be processed with nozzle sizes of 0.4 to 0.8 mm made of copper or hardened steel. Suitable print surfaces include BuildTak, glass, blue tape, or PEI, with the use of adhesive recommended. The spool is sealed and packaged with silica gel to minimize moisture exposure. For optimal storage, the manufacturer recommends a cool, dry environment at 15 to 25 °C without UV radiation.
