<p>The use of lasers for the manufacture of parts from bulk metallic glass (BMG) largely depends on the development of rational modes of laser exposure to the material. Rapid cooling is critical to prevent crystallization and achieve an amorphous structure. This article uses software developed and verified by the authors to simulate selective laser melting (SLM) and systematically study the conditions of laser processing of a multicomponent zirconium-based alloy. A new two-step method for calculating the thermal field has been developed, which allows for numerical studies of BMG recrystallization processes during multiple scanning. An optimal strategy for laser processing of a glass-forming alloy is necessary to solve the critical problem of the influence of heat accumulation and minimizing crystallization during repeated laser scanning. SLM strategies have been proposed in which it is possible to reduce the volume fraction of the crystalline phase in the surface layer of BMG of given limited dimensions by orders of magnitude.</p>
