N2 - In this paper, the Direct Croning (DC) process is compared to the Z-Cast process using the Analytic Hierarchy Process (AHP). This comparison is based on the use of these two Additive Manufacturing (AM) techniques for a specific casting application referred to as Rapid Casting for Tooling (RCT). RCT is the manufacturing of metallic tooling by casting in sand moulds produced by AM. The AHP criteria included the manufacturing time and cost, surface finish, dimensional accuracy and durability of cast tools. Experimental results are used for the pairwise comparison of AM alternatives and the determination of intensities. The research shows that the DC process using an EOSINT S 700 machine is superior to the Z-Cast process in a Spectrum 510 machine. The overall preferences of the two AM processes were found to be equal to 52% for DC and 48% for Z-Cast.
