3D Print Clay Nozzel

A quick introduction of how to make textures in 3D printed clay objects through adjustments of the extruder nozzel.

Make sure that dimensions are as close to the original as possible. If the nozzel it to large, it will slide into the extruder; to small and it will slip out. This might take a few test prints.

I used an FDM printer and it helps to put a raft bellow the 3D printed nozzel to prevent the PLA from spreading on the first layer.

After the nozzel is sized correctly, tests must be made to calibrate the extruder with the new nozzel. Play around with the extrusion rate and the layer height depending on the shape/size of the nozzel.

The images here show the results from a cross shaped nozzel head.

Here are some examples of the varieties of forms and textures that can be created with simple changing out the extrusion head.

I was able to successfully reduce the thickness of the extruder from 5mm to 2mm, but sticking to the circular aperture.

But the limits of how thin is still to be reached!
