The recently published book How to – Model the Additive Manufacturing Process by the NAFEMS Metallic Additive Manufacturing Focus Team, a part of the Manufacturing Process Simulation Working Group, offers practical advice on modelling the additive manufacturing process. The team has now gone further and devoted considerable effort to developing a suite of example problems that encapsulate the complexities of simulating the Additive Manufacturing (AM) process. The first problem revolves around the buckling phenomenon observed when printing thin-walled structures. The reader is encouraged to simulate the phenomenon based on the included and referenced information, and then share their experience with the community.

Revision note: Changes have been made to the online version of this article on 26 November 2024. These updates reflect corrections regarding the type of material used for printing the steel test specimens. Specifically, the originally mentioned 316L stainless steel has been updated to Tool Steel H13, based on newly clarified information. The material properties and related discussion have been revised accordingly to ensure accuracy in the presented findings.
