Directa Plus launches graphene-based 3D printing material

Directa Plus has launched GRAFYLON 3D, a polylactic acid-based (PLA) graphene-enhanced filament for 3D printing, which has been developed in collaboration with FILOALFA, a division of Ciceri de Mondel that specialises in producing filaments used in 3D printing. GRAYFLON 3D is claimed to be the first 3D printing product to contain the Company’s Graphene Plus.

Giulio Cesareo, CEO of Directa Plus, said: “Our Graphene Plus is produced from a chemical-free process that has been independently certified as non-toxic and non-cytotoxic. We look forward to working with FILOALFA and enabling them to further differentiate their filaments through the incorporation of our graphene-based products.”

The inclusion of Graphene Plus is said to enhance the filament’s properties, whilst maintaining a competitive price. During testing, GRAYFLON 3D showed an improvement in surface finish and thermal conductivity compared with non-graphene-based 3D filaments. It also showed a 34% improvement in elastic modulus, 23% higher tensile strength and 28% higher elongation.

“GRAFYLON 3D is the first of a new generation of filaments containing graphene developed with Directa Plus,” added Antonio Berera, R&D manager of FILOALFA. “We are working with Directa to produce graphene-based products to be used with other polymeric bases for our filaments, and look forward to bringing to the market further products with unique properties that will differentiate them from competing solutions.”
