Numerical and experimental investigations of a turbocharger with a compressor wheel made of additively manufactured plastic

Additively Manufactured Parts Made of a Polymer Material Used for the Experimental Verification of a Component of a High-Speed Machine with an Optimised Geometry—Preliminary Research

“…MJ technology makes it possible to select several types of light-curing resins with different mechanical properties. Due to the specified operating conditions [ 11 ], the most resistant material with the catalogue name of VisiJet M3-X (3D Systems, Rock Hill, SC, USA) with a tensile strength of 54 MPa and a softening temperature of 88 C [ 39 ] was used in the research presented in this paper. The material used in the research was chosen from two of the most durable materials offered by the manufacturer of the selected printing technology.…”

“…The material used in the research was chosen from two of the most durable materials offered by the manufacturer of the selected printing technology. The materials were experimentally tested to determine their tensile strength and maximum operating temperature and the results are described in papers [ 11 , 39 ]. The aluminium compressor disc comes originally from an industrial turbocharger used in this research and no design data is available.…”

“…Currently, AM is most often used in the medical industry [ 1 , 2 , 3 ], and its rapid growth is taking place during the COVID-19 [ 4 ] pandemic to produce all possible elements used to combat the pandemic and support the production of life-saving components [ 5 ]. A wide range of applications can be observed in industries such as stomatology [ 6 , 7 ], power engineering [ 8 ], aerospace industry [ 9 ] and even the automotive industry [ 10 , 11 ]. AM methods used to manufacture real 3D objects using the layer-by-layer technique use a few types of building materials, namely metals, polymers, ceramics and glass [ 12 , 13 ].…”

“…The aim of the paper is to present a tool for verifying the optimised shape of the blades of rotor discs (i.e., turbine disc and compressor disc), the manufacture of which is either very difficult or impossible using the conventional production methods (that is, machining, CNC milling, etc.). The results and considerations presented in the paper constitute a continuation of research on the use of polymer-based AM technologies for the manufacture of prototype parts of high-speed machines [ 11 , 38 ].…”

Preliminary investigations on extrusion of high viscosity slurry using direct writing technique

“…This technology is equipped with an ability to create complex 3D parts without the use of tooling, which can reduce up to 50% of the product lead time. Due to the strange feature of AM techniques such as time efficient, cost-effective and can print wide range of materials such as ceramics [4][5][6], metals [7][8][9], food [10][11][12] and thermoplastics [13][14][15]; the AM process attracted a great deal of attention in the areas of automotive [16], aeronautical [17], medical [18], robotics [19], electronics [20], construction [21] and consumer goods manufacturing [22]. Recently, the additive manufacturing of solid propellant has gained interest due to the ability to form complex and intricate shapes.…”
