Resonance Lamp

Resonance patterns, also called Chladni figures, are created when sound energy is applied to a metal plate. Loose sand is sprinkled on the plate, and the sand naturally collects into the low energy nodes generating an endless number of amazing patterns.The YouTube video linked below shows how the effect works. With over 9 million views in the last 3 years, it's certainly captured the attention of many, and I hope this lamp does as well!For this piece, I selected two of the patterns from the video and applied them to the lamp. Playing on the translucent nature of FDM plastic, I debossed the lamp where the nodes are, recreating patterns of dark and light on the surface.Because the base model is parametric, newly generated patterns can easily be applied to create an endless variety of lamps. To transfer the pattern from plate to lamp, I captured and vectorized a photo. This method captures little irregularities in the model and gives it more character, as opposed an equation that would generate the pattern procedurally.The model prints upside down with no supports and meets minimum thickness and overhang requirements that will ensure it prints well. If any of the dimensions need to be tweaked for a particular printer, the included parametric Fusion 360 file makes the process easy.Resonance is intended as a hanging lamp (with a fixture like this one: http://www.ikea.com/gb/en/catalog/products/80263709/) or can also work as a table lamp simply by moving the support structure from top to bottom in the model.
