Abstract

The rapid sand casting of sand moulds has gained significant attention in the foundry industry. However, existing technologies for this process are still quite expensive, and financial assessments are required to justify the adoption of this process in foundries. To that end, a paper was previously published on the financial feasibility of the Voxeljet VX1000 system using the payback period method. This study takes the analysis one step further by considering the time value of money by using a discounted payback period method. The accuracy of the two methods as a means of providing accurate results is compared to guide local foundry men in adopting this process in the local foundry industry.
