Abstract
This paper compares two commercial acid-cured furfuryl alcohol resins. The first material is used for conventional sand moulding (CSM), while the second material was manufactured for the binder jetting process (BJP) using a Voxeljet VX 1000 printer. To that end, chromite sand test specimens were prepared following the American Foundry Society (AFS) procedures to assess various foundry properties, including flowability and flexural strength. The study provides valuable insight into furan resins' properties and differences. In addition, the investigation provides an understanding of the requirements for a suitable local furfuryl alcohol resin for the binder jetting process to produce quality three dimensional printed sand parts.
