Directa Plus launches graphene-based 3D printing material

26/09/2016
Graphene-based products developer Directa Plus has added a graphene-enhanced filament for 3D printing, Grafylon 3D, to its range. This is the first 3D printing product to contain the Italian company’s Graphene Plus material. The new product has been developed in collaboration with Filoalfa, a division of Ciceri de Mondel that specialises in producing filaments used in 3D printing; it is now commercially available.

Directa Plus has described Grafylon 3D as a new generation of polylactic acid-based (PLA) filament containing its graphene-based product. In 3D printing, hundreds or thousands of layers of material are “printed” layer upon layer using various materials, most commonly plastic polymers such as PLA filaments.

During testing, improvements observed in performance compared with non-graphene-based 3D filaments included improvement in surface finish, thermal conduction properties, tensile strength higher by 23%, elongation higher by 28%.

Chief executive of Directa Plus, Giulio Cesareo, said: “We are delighted to launch Grafylon 3D. Our new filaments provide advantages over non-graphene-based filaments that open up new areas of application for 3D printing such as conductivity and material strength. We believe they can revolutionise industry standards in the 3D printing field.”

For its part, Filoalfa said it intends to continue working with Directa Plus and to use its graphene-based products with other polymeric bases for filaments.
