Colfeed4Print's FEco family of materials includes the FEco Graphene in filament format as well as in pellet format. The FEco Graphene pellets have a PLA base and inorganic content in the form of 15% of conductive graphene particles with a mean diameter of 503 nm and a specific surface area 180 m²/g. Parts 3D printed with these pellets have an electrical conductivity of 1000 S/m and can be UV-sterilized. The method of colloidal preparation employed for the feedstock facilitates achieving a significant level of dispersion for graphene particles within the polymer matrix.

For optimal printing results, adhere to the following printing recommendations: maintain a printing temperature of 170-180 ºC, with a bed temperature ranging from 50-60 ºC. A printing speed of 5-20 mm/s and a layer height exceeding 0.15 mm are advised. To safeguard the integrity of the pellets, store it in a dry, shaded environment within the temperature range of 5-30 ºC.
