Abstract
Fe-based bulk metallic glass shows superior mechanical, chemical and physical properties, but its inherent brittleness and micro-cracks hinder further applications. In this paper, a novel chessboard scanning strategy combined with laser re-melting was introduced to overcome the micro-cracks of Fe-based bulk metallic glass via selective laser melting (SLM). The chessboard scanning combied with laser re-melting strategy decreases the residual stress to 168 MPa, which is only 29% of that by traditional scaning strategy. This work provides a feasible route to process crack-free Fe-based bulk metallic glass components by using SLM.
