Abstract

Its transparency, aesthetic appeal, chemical inertness and electrical resistivity make glass an excellent candidate for small and large‐scale applications in the chemical, electronics, automotive, aerospace and architectural industries. Additive manufacturing of glass has the potential to open new possibilities in design and reduce costs associated with manufacturing complex customised glass structures that are difficult to shape with traditional casting or subtractive methods. However, despite the significant progress in the additive manufacturing of metals, polymers and ceramics, limited research has been undertaken on additive manufacturing of glass. In this study, a laser powder bed fusion method was developed for soda lime silica glass powder feedstock. Optimisation of laser processing parameters was undertaken to define the processing window for creating three‐dimensional multi‐layer structures. These findings enable the formation of complex glass structures with micro or macro‐scale resolution. Our study supports laser powder bed fusion as a promising method for the additive manufacturing of glass and may guide the formation of a new generation of glass structures for a wide range of applications.
