lecture: Gems are truly outrageous

Combining 3D printing and crystallisation techniques

Event large

This talk demonstrates how to make fake gemstones and related accessories using only a 3D printer and kitchen, as well as various pointers to make your own designs.


This talk demonstrates the age-old process of rock candy, while using 3D printed shapes as moulds for the crystallisation process. Covered steps are the basics of crystallisation chemistry, practical limitations for moulds, as well as post-processing steps to remove excess growth from your design.

In the overarching story, you will be taken through the process of designing a (slightly more realistic) replica of a hammer once used by the character Taric known from the League of Legends game. From this process the various steps and challenges will be explained in depth, giving the audience an opportunity to learn from the ideas and problems encountered in the creative process.
