RS 3D Printer Filament PETG. PET-G is a strong, high clarity, odor neutral and easy to print filament for 3D printing. These characteristics, together with the high impact strength, excellent flexibility and practically no shrinkage make PET-G an excellent material which combines the advantages of both PLA and ABS. The filament is hydrophobic and therefore does not absorb water. In short, PET-G has many great features and is the perfect addition to any filament assortment. High clarity Strong ; Flexible Almost no warping Hydrophobic (Does not absorb water) Food Contact Acceptable Odor neutral printing. Recommended temperature for heated bed is ± 35-60 C. Adhesion is possible on different surfaces. PET-G can be used on all common desktop FDM or FFF technology 3D printers. Storage: Cool and dry (15-25 C) and away from UV light. This enhances the shelf life significantly.
