Project Overveiw<\/h2>\n\n\n\n

My goal for this project was to print with glass using the affordable and accessible desktop Eazao clay printer. I developed a recipe for a paste made out of glass frit that could be easily printed with the Eazao. I then figured out a kiln schedule that would fire the printed pieces so the glass would sinter and stay together and also look like glass. I began by printing cylinders and using these to dial in both my paste recipe and my firing schedule. I learned that the hotter I fired the cylinders, the glossier they were, but they also slumped more. I originally thought that I could use this property for the computation side of my project. I was going to try to use some physics plugins for Grasshopper to predict the amount and shape of slumping given a geometry and temperature. I struggled with getting any of the cylinders to shrink uniformly without slumping and abandoned my original thought for printing more complex hollow geometry. I also pivoted away from trying to model the slumping.<\/p>\n\n\n\n

I decided to pivot to printing objects that were mostly flat or solid instead of hollow vessels. I started by writing some code that drew parametric 2D curves and turned them into gcode. I made a lot of earrings this way. I also used the tiling project to print a series of tessellating tiles in different colors that I could tessellate and fire to melt them together. Finally I tried printing some small solid 3D objects. I hoped that the solid nature of them would prevent the slumping I was seeing with cylinders.<\/p>\n\n\n

Background Research<\/h2>\n\n\n\n

Below are a few papers and documentation I found interesting and helpful. The first is by John Klein, Michael Stern, and Giorgia Franchin from Neri Oxman’s Mediated Matter group at the MIT Media Lab. They built a glass 3D printer that prints molten glass. I am hoping to be able to 3D print glass in a much more affordable and accessible way, but I thought it was a cool project to research and highlight. The next paper investigates making transparent silica glass through powder sintering. The third is about making glass-like sintered material from metallurgical waste. The last is technical documentation of heat and glass from Bullseye Glass, which is where we get our glass frit. <\/p>\n\n\n\n
