Project information
Glass 3D printing is moving from experimentation to real-world applications. In collaboration with Maple Glass Printing, the Glass Competence Center (GCC) at TU Darmstadt is showcasing innovative 3D-printed structures applied to flat soda-lime silicate glass. Using the advanced Maple 4 printer and Fused Deposition Modelling (FDM) technology, this breakthrough enhances facade design by combining structural efficiency with aesthetic flexibility.
Recent GCC research shows that stiffening flat glass with 3D-printed structures can reduce material use by up to 70% compared to conventional glass. This advancement improves sustainability while enabling the production of insulating glass with integrated 3D structures, custom lettering and patterns, and functional elements such as shelves and door handles. With nearly unlimited design possibilities, 3D-printed glass offers economic and ecological benefits for architecture.
A key factor driving this progress is the “3 Keys to Innovation” strategy at GCC. By fostering age diversity in research teams (I), integrating craftsmanship with advanced technology (II), and maintaining strong industry collaboration (III), the center continues to push the boundaries of glass 3D printing.
With its combination of efficiency, versatility, and sustainability, this technology is set to redefine the future of facades.
