Two Point Interference Pattern

thingiverse

These patterns are generated by two wave sources operating at the same frequency, similar to those found in a ripple tank. The simulation was conducted using an online wave simulator located at https://www.falstad.com/ripple/, and the B/W image captured at full screen was used to feed the "Image to 3D" function in Simplify3d. The resulting .STL file is based on the light and dark areas in the B/W image but is very coarse. The mesh was subdivided twice, and controls were refined in Silo to produce these two files, one large (34 MB) and the other larger (137 MB from 2 subdivisions). Printouts are "hairy" and require additional work. By lowering the model in the printout and not printing any base layer, a screen can be created as seen in the last image. The same principle applies to the other wave images I'm uploading. These patterns could make very cool room dividers in 3D or could be laser cut.
