Carbon Nanotubes: LATI3Dlab Revolutionises 3D Printing with Conductive Sensors

Discover how LATI3Dlab uses carbon nanotubes to lower electrical resistivity in plastic compounds for 3D printing. The technology used for Filoalfa’s Alfaohm filament, derived from this innovation, can be used to create conductive sensors used in medicine with outstanding results.

LATI3Dlab, a LATI spin-off specialising in thermoplastic compounds for 3D printing, has achieved a new milestone in the creation of electrically conductive materials. The introduction of carbon nanotubes and structured carbon black has made it possible to lower the electrical resistivity to less than 10Ω in PLA-based plastic compounds. This innovation offers extraordinary homogeneity and isotropy of electrical properties, regardless of the deposition method and infill.

The Alfaohm filament, developed with this technology and marketed by Filoalfa, was used by Dr. Jesús E. Contreras-Naranjo and his team to 3D print conductive sensors for medical applications. These sensors, activated with a specific surface preparation, have been shown to conduct electrical signals from electroanalytical devices, revealing the presence of chemical substances.

The advantages of this technology, such as fast manufacturing times via the FDM process, adaptability to customised designs and competitive cost, pave the way for innovative applications such as supercapacitors, lithium-ion batteries and solar cells in the hybrid or electric vehicle sector, confirming the revolutionary potential of 3D printable conductive compounds.
