The Swirl vase was made with two finely balanced Bézier curves.
Fun facts :
In order to hold water and prevent leaking, the print process is very slow, taking about three days to produce a single vase.
The print process creates ‘charming’ surface artefacts that are visible up close. One of them is called a Z Seam, which is a vertical mark at the place where the print head moves up along the z-axis during printing (see photo of Pearl version). Also the texture is that of extremely fine horizontal grooves, that feels a bit like an old vinyl record surface.
These had been tested to hold water, and passed.
