3D printed sand cores and moulds are finding increasing use in Danish foundries for production of very complex components for pumps, impellers and other high performance parts.

Cores and moulds are built in a process where layers of sand are laid out in a building chamber and then bonded with a binder, which is dosed in a nozzle similar to an ink-jet printer.

This building process produces sand moulds an cores that are more permeable than the moulding sand normally used in foundries where almost all processes involves a physical densification or packing of the sand.

The quality (strength and surface roughness) of the castings produced in sand moulds depends on how the metal is cooled in the mould. It is therefore important to know the properties of the printed sand moulds, and how they differ from moulds produced by traditional methods.

In this project, we offer a combination of experimental studies of heat flow in sand combined with inverse modelling to determine properties such as thermal conductivity and thermal expansion of printed sand and sand produced in traditional processes.

The project will be carried out in collaboration with a Frese Metal- og Stålstøberi in Slagelse. They specialise in production of high integrity parts for the marine and offshore industries in bronze and stainless steel. https://www.frese.eu/foundry/en-GB
