“It has always been the objective of Graphene 3D to create new opportunities for 3D printing. With every functional filament we introduce to the market, the types of 3D projects that can be successfully printed expands exponentially,” said Elena Polyakova, Co-CEO of Graphene 3D. “As this filament is ideally suited to switches, sensors and actuators, we also expect this new functionality will challenge more traditional manufacturers to examine incorporating more 3D printing technology into their manufacturing processes.”
The magnetic filament is available in 1.75 mm diameter, in 350-gram quantities for $39.99. The color is flat black, giving printed objects a cast iron appearance. Because of the iron content, the filament is more brittle and abrasive than standard PLA, so expect some increased wear on your nozzle; Graphene 3D Labs suggests doing a first level adjustment and using a larger or wear-resistant nozzle for longer prints. Unlike other iron products, however, it’s unlikely to rust.
The filament really does carry a powerful magnetic charge; for best results, Graphene 3D Labs recommends using neodymium iron boron (NdFeB) or samarium cobalt (SmCo) magnets with it. The filament prints at a temperature of 215° to 225° Celsius; a heated bed can be used at 60° but is not required. Print speed is about 60 to 80 mm/s.
“We expect 2016 to be a significant year for Graphene 3D in terms of introducing new functional filaments,” said Daniel Stolyarov, Co-CEO. “We have several new functional filaments in the development pipeline and we expect to release several new filaments throughout the year. Availability of a large selection of functional 3D printing materials enlarges the capabilities of additive manufacturing allowing you to print projects that will only be limited by your imagination.”
