A concept of a test stand for the investigation of a 3D printed turbochargers and selected fluid-flow machinery

The paper describes the general concept of using the rapid prototyping methods and their application tomanufacturing of selected components of rotating machinery. Chosen rapid prototyping technology (multijet printing) allows precise manufacture of rotor models with complex geometry, without the need for their further processing. The research is planned to be performed on designed test rig, which is described in the paper. 3D printed elements will be pretested using air from a high performance compressor. Basic preliminary testing and own experience has shown that this technology is faster, cheaper and more accurate than conventional manufacturing. This fact can significantly contribute to the development of production and research of prototypical fluid-flow machines. The tensile strength testing of the two materials which are used in a 3D printer in different printing directions has been also discussed.
