Glass Fused Modeling Deposition (GFDM)
2013-2016

The GFDM process was developed at the Rhode Island School of Design.  Glass is ladled from a furnace at 2200˚F (1200˚C) into a printer kiln.  The kiln contains a crucible with a hole drilled into its bottom. This aperature is aligned with an opening in the bottom of the kiln.  The printer kiln is held at a temperature around 2000˚F as it deposits a stream of glass onto a printing plate.  The robotic manipulator moves the printing plate while hot glass is deposited on its surface.  The robot moves according to programmed tool paths that determine the movement of the plate, which in turn, dictate the form of the glass object.  More documentation of the process is here.  

This gravity fed glass printer demonstrates emerging patterns that align with viscous rope coiling and the "fluid mechanical sewing machine". This process explores natural emergent patterns and form-finding phenomena of glass. Inherent material properties dictate form and structure.
