Three-dimensionally (3D) printed sand molds for custom glass parts

Abstract The presented research investigates a digital fabrication method for custom glass building elements based on three-dimensionally (3D) printed molds. Custom parts with specific geometries usually require several steps of manufacturing, highly specialized craft, or machinery. Computer Numerical Control milled steel molds are only suitable large lot sizes due to their high cost and limited geometric freedom. Lost-wax casting requires manufacturing post-processing. This paper an accessible, low-cost process shaping artifacts using 3D-printed close the gap between mass-produced custom-crafted elements. Previous has demonstrated potential binder jetting inorganic binders casting. range traditional methods besides that can be combined molds, including foundry kiln casting, blow molding, slumping. aim is extend possibilities provide approaches three-dimensional glass. goal simplify from design production solid, hollow, doubly curved sheet precision. presents investigations techniques material considerations, heat resistance, compatibility different glass- making processes, coatings mold treatment. Furthermore, precision resulting evaluated, guidelines typologies defined. Glass bricks sheets facades features enabled by could allow novel optical, structural, decorative properties in
