Additive manufacturing of bulk metallic glasses (BMGs) through laser powder bed fusion (LPBF) has drawngrowing interest in the last years, especially concerning industry-relevant alloys based on iron or zirconium.The process-inherent high cooling rates and localized melting pools allow to overcome geometrical restrictionsgiven for the production of BMGs by classical casting routes. Yet, the achievable surface qualities are still limited,making an adequate post-processing necessary. In this work, we report on applying thermoplastic forming onLPBF-formed parts for thefirst time to decrease surface roughness and imprintfinely structured surface patternswithout the need for complex abrasive machining. This BMG-specific post-processing approach allows tofunctionalize surface areas on highly complex LPBF-formed specimens, which could be of interest especiallyfor medical or jewelry applications
