Graphematech and Add North 3D develop novel graphene-enhanced 3D printing filaments

A collaboration between two innovative material technology startups Graphmatech and Add North 3D (a Swedish 3D materials developer specialized in FDM materials) has developed novel conductive Aros Graphene-based filaments for 3D printing. This may open up many new different 3D-printing applications such as thermal management components, circuit boards and efficient electromagnetic and radio frequency shielding.

The recently developed 3D-printing technology based on Graphematech's Aros Graphene may grant the ability to control the exact level of conductivity of the filament. The new filaments will now be optimized and go through beta testing with a reference group before it is expected to reach the market in 6-12 month.

Graphene-coated smart contact lenses could protect eyes from EM radiation and dehydration

Researchers at Seoul National University, Graphene Square and Interojo have shown that graphene-coated contact lenses could protect eyes from electromagnetic radiation and dehydration and be used in various healthcare and wearable technologies.

The researchers began by synthesizing a graphene layer on a copper foil using CVD. They then transferred the carbon sheet onto the surface of a contact lens with the help of a polymer layer after etching the copper. "Thanks to its outstanding flexibility, graphene can be coated on the convex lens surface and conform to it," explains the team.

GNext's graphene-based inks to soon enable recyclable EMI shielding sheets

Last week the Graphene-Info team visited the MWC - the world's largest mobile technologies conference held in Barcelona, which this year included a graphene pavilion, organized by the ICFO and the Graphene Flagship, Europe's $1 billion research project initiative.

One of the companies showcased in the pavilion was the Italy-based GNext, that demonstrated its graphene-based ink, used for rapid fabrication of electronic devices. GNext's ink can be printed using many common techniques on a wide range of substrates, including biopolymers such as PLA, and achieving a volume resistivity below 4 ohm/sq/mil.
