I have spent most of my time figuring out the recipe and firing schedule for the glass. I went through a lot of iterations of the recipe where I tweaked the ratio of glass to binder. I settled on the following recipe. It also required a lot more water than I thought to get it to extrude through the 3D printer. The final consistency is a frosting like paste<\/p>\n\n\n\n

Updated Timeline<\/h2>\n\n\n\n
\n
Dec 1: Dial in a kiln program that will sinter the cylinders into glass without slumping. <\/li>\n\n\n\n
Dec 6 : Print larger and more complex geometries and figure out how to fire them without slumping. <\/li>\n\n\n\n
Dec 8: Finish writing my grasshopper and Kangaroo code<\/li>\n\n\n\n
Dec 12: Make lots of objects!<\/li>\n<\/ul>\n\n\n\n
Updated Deliverables<\/h2>\n\n\n\n
\n
A reliable recipe for a paste made from glass frit that can be printed with the Eazao clay 3D printer. <\/li>\n\n\n\n
A kiln program(s) that works with the recipe above to fire the 3D printed objects into glass. <\/li>\n\n\n\n
A range of possible sizes and types of forms that work with this process.<\/li>\n\n\n\n
Five to ten objects 3D printed and made out of glass.<\/li>\n\n\n\n
Grasshopper scripts that generate the gcode for the type of 3D prints that will work with this method. <\/li>\n\n\n\n
A grasshopper definition that takes in a form, the nozzle size that was used to print it in glass, and the firing temperature and uses the Kangaroo plug-in to predict the shrinkage and slumping that will occur in the final shape. <\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
