All the advantages and ease of printing of PETG with the high mechanical strength of carbon fiber.

The PETG is a modified version of the previous PET. Polyethylene Glycol Terephthalate (PETG) is a non-toxic thermoplastic polymer used in the manufacture of clothing and in products such as containers. PETG filaments have gained much popularity due to their low molding temperature and durability, so it isn't surprising that manufacturers develop new materials from PETG.

The Nanovia PETG CF stands out from the rest of the market with a carbon fiber size optimized for 3D FDM printing. This distribution of the fibers frees the printer's extruder from jamming, but even so it's recommended to use a nozzle larger than 0.4mm, as in many other filaments with high quality fibers (XSTRAND GF30-PPXSTRAND GF30-PA6Timberfill Light Wood ToneTimberfill RosewoodTimberfill ChampagneTimberfill CinnamonSmartfil E.P. and etc). Apart from that, the PETG CF together with the PLA is one of the easiest and most stable materials for printing parts and models regardless of their size.

On the other hand, the development of this filament has also managed to obtain values of mechanical strength (Traction Module: 4700 MPa) so high that they are only surpassed by really advanced materials (PEI CF, GF30-PPGF30-PA6 and few others). Due to its high carbon fiber content the PETG CF has a very high resistance to brittle breakage and high rigidity.

The great dimensional stability obtained with the fusion of the PETG with the carbon fiber, results in an extremely durable material even in adverse environments for many other materials used in 3D printing.

The PETG CF is a material oriented for users who need to make structural parts and exposed to high mechanical stresses. This is why many branches of engineering and even medicine use this material to make their prototypes and final pieces. In particular, the paramedic field usually uses this material to make accessories and components for their patients, such as prosthetics or adaptable parts of wheelchairs.

The PETG CF (PETG with carbon fiber) of Nanovia is an ideal material to replace temporary functional pieces or permanent metal with medium loads, which can be made a post-processed (sanding, painting, etc.) with total peace of mind. In addition, the PETG CF is compatible with the majority of 3D FDM printers on the market and with any standard nozzle (brassequal to or greater than 0.50mm in diameter.

3D printing with PETG filament is just as simple as with the PLA filament. In the case of the PETG CF filament, it's necessary that the printing base is hot, between 80 and 100ºC. In addition, the temperature of the extruder should be between 200 and 240ºC. In the case of printing large pieces it's advisable to use BuildTak, Kapton TapeMagigoo or DimaFix so that the pieces don't tend to detach from the base. To ensure the dimensional stability of the parts it's advisable to use a closed 3D printer.

With the PETG CF it's necessary to use a nozzle of 0.50mm in diameter or more but it isn't necessary to use a reinforced nozzle since this filament has low abrasion. Even so it's recommended to use the Nozzle Olsson Ruby for all advanced materials.
