Project Two Progress

    I've settled on making my jewelry design a tiara, but I'm still figuring out the final design that will be. I've been experimenting with various tools to create geometric patterns for the tiara. I'm mainly inspired by the inclusions formed in the rainbow lattice sunstone in the concept post for this project, but I've also been exploring more curved geometry inspired in part by mathematical topology.

    Something that needs to be considered for my concept to work, is that for the tiara to be printed as a negative cavity that can be filled with liquid, is that all piece of the tiara must be connect, with the smallest cross section to be no smaller than 2mm in order to ensure printing clearance for the gap, and that the surface tension of the liquid I use to fill the cavity doesn't keep air bubble from escaping.

    I am also contemplating another method to reach similar outcome, where I instead 3D print only the outer shell of the tiara, or tiara parts, fill them with liquid, and then arrange them in a mould to cast them in resin directly. Some preliminary tests of the clear PLA showed that the micro gaps between lines and layers scatters light a little too much for the inside to be visible. This could play to my advantage, where the object represented by the cavity is both unwearable, and visually obscured, but I'm not sure that would land or communicate well to others. Further testing is needed.

    Here's one of the patterns I was drafting to create more of a three dimensional lattice that resembles the lattice inclusions of the sunstone.

    Here I was experimenting with the helix tool, creating helices, rotating some copies, and sweeping a square profile along them

 

 

     

    Here I took a circle, twisted it by 180 degrees end to end, generated two helices around that curve, and their reversed helices, generated pipes on all the curves, and subtracted the piped helices from the twisted circle helix.

 

    Here I created a simplistic 2D lattice, extruded it, and used the flow along surface tool to wrap it around the arc of a cylinder.

    Here I took a semicircle on the ZY plane, placed a 1/3rd sized copy further along the X axis, tweened 15 copies between them, extruded them in the positive X direction by 2mm, offset the resulting surfaces by 2mm, mirrored them over the ZY plane, placed 2mm by 2mm wide box along the length under the arches, grouped them, and used flow along surface to wrap them around the arc of a cylinder.
