Abstract
Advances made in Additive Manufacturing (AM) or 3D printing led to the 3D printing of sand
moulds and cores used in the foundry industry. Ideally, the mechanical properties of the 3D
printed moulds and cores should be uniform throughout the 3D printed part. This will ensure
that the casting produced from the 3D printed mould has uniform properties throughout the
mould. The following study investigated the effect of the printing location and part
orientation in the AM machine used to produce the 3D Printed mould on the bending strength
property of sand parts. Several printing orientations and angles were considered in the
investigation. Descriptive statistics was used to assess and interpret the results.
