3D Printed Conductive Materials

Conductive materials can be incorporated into different filaments or deposited with syringe or inkjet tools. These can be conventional metals (silver, nickel, gold, copper)  or conductive polymers such as PEDOT:PSS or carbon in graphene, nanotube, or carbon black forms. Graphene is commonly either incorporated into a polymer composite (PLA etc.), or in inkjet printable form.  The table below compares several products on the market.
