Week 13: Molding and Casting¶
*The final four-part gypsum mold
Group Assignment¶
For the group assignment it was Mariam, Ani, Gevorg, and Hrach [me]. Ani and Gevorg are the students from Gyumri node, but to conduct the stafety training, and on-sight lecture we worked all together.
Safety Training¶
Methods¶
CNC¶
3D Printed¶
Casting¶
Individual Assignment¶
Negative Mold¶
Achieving this form was quite simple. I first imported the .svg file of my favicon. Then I extruded the shape to a desired thickness, and cut it out of a extracted square.
The Idea¶
I drink coffee everyday! I make my coffee using various tools, gadgets, methods and recepies. In fact, in my home section you can also find an interesting poster on a research I conducted studying coffee bean changes during roasting. So naturally, I dedicated an individual project to making something related to coffee, in this case a cofee dripper.
Not to complicate the design, or spend time on developing prototpes, I decided to trace the design of the funnel I am using to prepare my daily filter – a Hairo V60.
The Method¶
*Prompt13.1, involves a lot of fixing in Figma
Slip Casting¶
I began by uploading the profile image aof the funnel, and started tracing the profile curves. After obtaining the desired shape, I proceeded to revolving the sketch around the y-axis to create the 3D cone shape.
Project 2¶
After having achieved the final form, I started subtracting it from more simple solid bodies.
Conclusion¶
Yet again, I experienced something that I had been wanting to try for a long time. As I have experience in pottery, I had already tried slip csting. So advancing from to mking my own gyspsum mold was a complete new discovery.
Though I wish I had tried more molding techniques, such as sand casting, metal block milling, maybe even glass blowing. I will probably come back to wax milling.
Making a three-part mold was an interesting puzzle for me.

Prompts¶
Prompt13.1 Create a clean, technical infographic showing the 6 step industrial process of transforming a 2D logo into a ceramic piece. First, 3D printing an extruded plastic master shape. Second, pouring liquid silicone over the print to make a flexible mold. Third, casting liquid resin into the silicone mold for a durable copy. Four, pouring plaster over the resin copy to create a ceramic slip mold. Fifth, filling the plaster mold with liquid clay [a slip cast] to create the final ceramic form. And as final, sixth, step firing the dried clay form in a kiln. Minimalist isometric style, clear arrows, labeled steps.
