“…Future work will investigate methods of exact geometry measurement. However, the difference between the hydraulic performance of the 3D-printed model and that of the commercially available model was small, and several blood pump developers have concluded that hydraulic evaluation is effective for 3D-printed blood pumps [1][2][3][4][5]. Therefore, 3D printing is an effective method of confirming the hydraulic performance of a pump.…”

“…They concluded that the PGF method was the most viable and feasible method of producing prototypes, whereas the MJ method produced the best surface roughness, yielding a roughness profile with an arithmetic average of less than 10 lm where the layer thickness was 12.5 lm. Rajenthirakumar et al [5] presented a design system for manufacturing an industrial centrifugal pump impeller using the PGF method and tested the performance and hydraulic efficiency of the manufactured centrifugal pump impeller. Throckmorton et al [6] manufactured an impeller prototype for an axial flow blood pump using the SLA method and completed the numerical modeling of the pump using computational fluid dynamics analysis, hydraulic testing, and hemolysis experiments with the pump.…”

An impeller the same geometry as the impeller of a commercial monopivot cardiopulmonary bypass pump was manufactured using 3D printing. The 3D-printed impeller was integrated into the pump casing of the commercially available pump to form a 3D-printed pump model. The surface roughness of the impeller, the hydraulic performance, the axial displacement of the rotating impeller, and the hemolytic properties of the 3D-printed model were measured and compared with those of the commercially available model. Although the surface roughness of the 3D-printed model was significantly larger than that of the commercially available model, the hydraulic performance of the two models almost coincided. The hemolysis level of the 3D-printed model roughly coincided with that of the commercially available model under low-pressure head conditions, but increased greatly under high-pressure head conditions, as a result of the narrow gap between the rotating impeller and the pump casing. The gap became narrow under high-pressure head conditions, because the axial thrust applied to the impeller increased with increasing impeller rotational speed. Moreover, the axial displacement of the rotating impeller was twice that of the commercially available model, confirming that the elastic deformation of the 3D-printed impeller was larger than that of the commercially available impeller. These results suggest that trial models manufactured by 3D printing can reproduce the hydraulic performance of the commercial product. However, both the surface roughness and the deformation of the trial models must be considered to precisely evaluate the hemolytic properties of the model.

“…Nonetheless, the RPLA impeller produces 93% less environmental impact than the VPLA impeller. Added to the latter research, computational fluid dynamic (CFD) analysis has also been conducted on a centrifugal pump impeller to calculate and enhance the overall performance and the efficiency of the impeller [25][26][27]. Also, a CFD analysis has been conducted to calculate the velocity and pressure contour alongside the blade of the impeller as well as the cavitation phenomenon which causes significant loss of performance and degradation of life in the centrifugal pumps [28][29][30].…”

Centrifugal pumps are used extensively in various everyday applications. The occurrence of corrosion phenomena during operation often leads to the failure of a pump’s operating components, such as the impeller. The present research study examines the utilization of composite materials for fabricating centrifugal pump components using additive manufacturing as an effort to fabricate corrosion resistant parts. To achieve the latter two nanocomposite materials, carbon fiber reinforced polyamide and carbon fiber reinforced polyphenylene sulfide were compared with two metal alloys, cast iron and brass, which are currently used in pump impeller manufacturing. The mechanical properties of the materials are extracted by performing a series of experiments, such as uniaxial tensile tests, nanoindentation and scanning electron microscope (SEM) examination of the specimen’s fracture area. Then, computational fluid dynamics (CFD) analysis is performed using various impeller designs to determine the fluid pressure exerted on the impeller’s geometry during its operation. Finally, the maximum power rating of an impeller that can be made from such composites will be determined using a static finite element model (FEM). The FEM static model is developed by integrating the data collected from the experiments with the results obtained from the CFD analysis. The current research work shows that nanocomposites can potentially be used for developing impellers with rated power of up to 9.41 kW.

“…Rajenthirakumar and Jagadeesh 20 set out to compare the performance differences of three different impeller models, which they modeled with the computational fluid dynamics (CFD) method, by manufacturing them with the selective laser sintering (SLS) method. They compared the CFD analysis results and experimental results of these impellers for three parameters and finally obtained similar results (Table 1).…”

The fused deposition modeling (FDM) technique which is one of the 3D printing technologies was used to produce a centrifugal pump impeller. The fabrication and investigation of the impeller were preferred because of its complex geometry and the difficulties encountered in its production. The most commonly used ABS, HIPS, PLA, and carbon fiber filaments were preferred to compare and determine the most suitable material for the production of the impellers. Firstly, mechanical test specimens from four different materials were printed in the 3D printer according to standards. Then the tensile tests and quasi-static punch shear tests (QS-PST) were applied to determine the mechanical properties of the 3D printed parts. Also, the mechanical tests were repeated to some specimen with the different fillings to define the optimum fill rates. Secondly, the impellers were fabricated from four materials by using the 3D printer in determined fill rates. Then, these impellers were mounted in the actual pump system, and pump performance tests were performed. In the pump performance tests, the head, pump efficiency, and electric power parameters were measured against the flow rate for each impeller. Finally, the mechanical properties and pump performance of the impellers compared with the GG25 cast iron impeller which is produced by traditional technique. As a result, PLA was selected as the most appropriate material for the production of the impellers. Furthermore, PLA showed superior performance compared to others when price, production time, and product weight parameters were considered.
