End Effector Design Over the course of the workshop we have developed both a manual and semi-mechanical method for additive clay printing.

Using the manual end effector revealed dificulties with the line accuracy and pressure consistency.

Our end effectors for the robot arms are pressurized in order to provide a consistent extrusion during the execution of our generated toolpaths.

Based on the clay mixtures that were tested, we were able to develop a series of prints that can stack on top of each other in order to achieve height

Gradient, Geometry & Branching Experiments When we transitioned from Manual to Robotic extrusions, we had the desire to create intricate shapes. Our first insinct was to investigate bifurcation. After multiple failures due to pressure control, we decided to make height our priority. In order to achieve height, we decided to extrude first simple geometries

Taller + Wider Prints with Nachi Our test of simple geometries revealed to be successful up to a certain height and width. We then decided to opt for more culvinear form to add structural capailities to our objects
