Abstract: Multiscale Modelling of Selective Laser Melting

Dr Milan Patel

RMIT is participating in a CSIRO-NTU Singapore-led project to develop cutting-edge simulation models of additive manufacturing – specifically the Selective Laser Melting process. This project will combine high-definition continuum fluid dynamics at the part scale, which models powder melting & melt pool tracking, with phase-field modelling at the grain scale that predicts solidification rate and finished-part microstructure. ‘Live’, bidirectional data exchange between these two sub-models permits the most accurate predictions of both the behaviour of the SLM process & the microstructure of the finished part to be obtained from one simulation platform.

All coding is performed using open source platforms, allowing for rapid technology transfer to industry partners. Enquiries should be addressed to dayalan.gunasegaram@csiro.au.
