Abstract

Bio-based powders are produced from renewable resources such as plants, agricultural waste, or even algae. These materials offer a compelling alternative to conventional plastics, which are often obtained from fossil fuels. New types of powder materials for the 3D printing process need to be characterised. They play an important role in 3D printing technology. Based on the results from testing, process parameters can be adjusted. There are currently no standardised methods for the testing of 3D printing materials. The moulding sand material has the same material properties as the renewable bio-based powders used for 3D printing.

In order to efficiently characterise the material, conventional foundry sand testing methods were considered. In this study, the existing testing facilities of the foundry industry were used to test the properties of Miscanthus, a plant in the grass family.

The results show that the universal testing machine can be used for general characterisation of relevant material properties, but modifications to the specimen geometry and testing technology are required for in-depth investigation of new powder materials for the 3D printing process.
