In this project, you will design a 3D model of an extruder die with a negative shape cut into it. You will 3D print the extruder die and use it to create unique extrusions that can be used in either your sculptural or wheel-based work.
What you will learn:
– How generate and manipulate shapes using the “shape generator” tools in Tinkercad.
– How to use negative shapes to bevel positive shapes in a digital model.
– How to size a digital model so that it fits within an existing tool.
– How to use the clay extruder with your unique 3D printed extruder die to create new forms that can enhance your clay objects.
The following tutorial walks you through how to design a extruder die. Again, make sure you have completed the other Tinkercad tutorials first, especially the “overview” tutorial HERE.
Once you have exported your extruder die model into an STL file, import it into Cura to prepare it for the 3D printer.
The list to the right are the settings you should use to 3D print your extruder die. These settings have been tested on the Monoprice Mini and the Monoprice MP10 and both worked well.
Make sure your extruder die has a width of 110mm and a height of 15mm. This will allow it to work with the Brent Extruder at the IUS Ceramics studio.
