Abstract

The use of Rapid Prototyping technologies for the production of sacrificial sand molds for the foundry industry has been previously researched, but with Selective Laser Sintering as the main technology, and with different methods of processing, and materials, as critical variables. With the proliferation of 3D printers and the relatively easy and economical production of moulds with special sands supplied by Z-Corporation, it is time that direct metal casting through 3D printing is scientifically investigated. Knowledge of the influence of various process parameters on the quality of moulds and subsequent castings is essential in effectively employing direct metal casting in real-world applications. This paper presents results of experimental investigations carried out to establish the influences of critical factors, such as curing times and temperatures, on mechanical characteristics, such as strength and permeability, of sand moulds produced by 3D printing. Statistically designed experiments are employed for the systematic analysis of the individual roles of critical curing parameters, as well as their combined effects.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
