Introduction
This page comprises a literature review of 3D printing with electrically conductive materials.
"Rapid prototyping of electrically conductive components using 3Dprinting technology"
- made of plaster-based powder bound layer-by-layer by an inkjet printing of a liquid binder
- impregnated by a dispersion of carbon nanofibers (CNF) in epoxy resin
- Surface resistivity of the model below 800 Ω/sq has been obtained when impregnated by a mixture containing less than 4 wt.% CNF. Volume resistivity of the molded and hardened CNF dispersion used for model impregnation have also been measured and a value less than 200 Ω cm has been obtained at 3 wt.% CNF content
- carbon-black or metal powders increases the viscosity of the infiltrant so that it is not able to impregnate the 3D model structure
- the average diameter of the fibers is 100 nm and typical length is 50–200 μm
