The purpose of the present investigation is to study the feasibility of decreasing the shell thickness for a statistically controlled rapid casting solution of lead alloy using three-dimensional printing technology. Starting from the identification of a component/benchmark, technological prototypes were produced with different shell thickness. Measurements on a coordinate measuring machine helped in calculating the dimensional tolerances of the castings produced. Some important mechanical properties were also compared to verify the suitability of the castings and further results are supported by microstructure analysis. The study suggested that the shell thickness having a value less than the recommended one is more suitable from a dimensional accuracy and an economic point of view. The provided data from the experimentation are extremely useful for the industrial application of the considered technology. The result indicates that at 1 mm shell thickness, the hardness of the casting improves from the recommended 12 mm. Further, production costs and production time have been reduced by 45.75 and 43 per cent, respectively, in comparison with the 12 mm recommended shell thickness.

Three dimensional printing (3DP) as rapid casting (RC) solutions has transformed over centuries from black art to science, but the metallurgical impinge on the process responsible for change in mechanical properties (like: surface finish, hardness, dimensional stability etc.) are still disputed. The purpose of the present research paper is to review metallurgical affect of 3DP based RC solution. The result of study suggests that prominent reason found to be responsible for improving the mechanical properties of RC is control of heat transfer rate while solidification (thus reducing dendrite formation).

Purpose The purpose of this paper is to investigate the process capability of three-dimensional printing (3DP)-based casting solutions for non-ferrous alloy (NFA) components. Design/methodology/approach After selection and design of benchmark, prototypes for six different NFA materials were prepared by using 3DP (ZCast process)-based shell moulds. Coordinate measuring machine has been used for calculating the dimensional tolerances of the NFA components. Consistency with the tolerance grades of the castings has been checked as per IT grades. Findings The results of process capability investigation highlight that the 3DP process as a casting solution for NFA component lies in ±5sigma (s) limit, as regards to dimensional accuracy is concerned. Further, this process ensures rapid production of pre-series industrial prototypes for NFA. Final components prepared are also acceptable as per ISO standard UNI EN 20,286-I (1995). Originality/value This research work presents capability of the 3DP process supported with experimental data on basis of various process parameters for the tolerance grade of NFA castings. These statistics can help to enhance the application of 3DP-based NFA casting process in commercial foundry industry.
