Conductive, flexible TPU introduced for 3D-printing applications

Graphene 3D Lab Inc. (Calverton, NY) has introduced an electrically conductive and flexible filament for 3D printing. The thermoplastic polyurethane (TPU) material is suited for wearable devices and other flexible electronics applications.

The enhanced properties of this product make it ideal for applications involving flexible sensors, electromagnetic interference (EMI) and radio-frequency (RF) shielding and flexible conductive traces and electrodes used in wearable electronics as well as medical devices, trackpads and many other products, according to the company. EMI and RF shielding is widely used in a range of industries—including aerospace, automotive, and medical—to protect against competing signals that may lead to false readings on equipment, noted the company. The filament is available for purchase in 1.75-mm-diameter, 100-gram spools under the trade name Conductive Flexible TPU Filament.

Upgrades to the company’s production facility and extensive research performed by its staff has “given us the opportunity to now offer an exciting new product that will feature two of the most highly sought after 3D printing properties—flexibility and conductivity,” said Elena Polyakova, co-CEO of Graphene 3D Lab, in a prepared statement.

"By adding the Conductive Flexible TPU Filament to our product line of functional 3D-printing filaments, we have expanded the capabilities of 3D printing, thereby shortening the road from the development to the commercial application,” added co-CEO Daniel Stolyarov. "We believe that our new filament will perform well in thriving entrepreneurial communities such as with developers of new wearable electronics products." 

Graphene 3D Lab claims to be the world leader in the development, manufacture and marketing of graphene and other 2D crystals as well as composites based on these nano materials. It operates three commercial divisions dedicated to R&D, 3D printing and industrial graphene-enhanced composites.
