Additive Manufacturing technologies use different materials for producing of design parts. Most used technologies of additive manufacturing are Fused deposition modelling (FDM) which use plastic wires for deposition of parts layers. There are also others technologies which use for example resins, paper, plastic powder but also steel and producing of parts from metal powder. Also in plastic materials is wide range of polymers which are suitable for FDM technology. Conventional materials are ABS, PLA, Nylon, PETG and others polymers. There are also special composites where the base is conventional polymer and particles of other solid material as glass, metal, wood which give to produced parts specific properties or appearance. Very specific material is conductive material which can conduct the electrical current. Presented paper deals with using of conductive PLA filaments for part producing. There are described results from scientific experiments which are prepared by standard methods and evaluated by statistical methods. Measured are material properties and electrical resistance.
