dodecahedral isosurface thing

pinshape

An isosurface with intricate dodecahedral patterns unfolds before your eyes. Printer Settings: Eaglemoss Vector3 Rafts: Irrelevant Supports: Unnecessary Resolution: 0.2mm Infill: 20% Notes: To ensure a solid grasp on the build plate, I sliced the bottom to expand its surface area in contact and employed a generous brim for extra sticking power. Due to its creation method, it requires significant scaling up before becoming a sensible size for printing. Design Process I started with some code provided to my students as an introduction to 3D graphics projects. This code helps them create models programmatically within Vertex and Index Buffers. Next, I sourced the Marching Cubes function from an online resource, adapted it to feed in an equation and produce a Vertex Buffer containing the given isosurface of that equation, then displayed and exported as a basic obj file. A 2012 post on the K3DSurf forum about isosurfaces led me to the equation below. I input this obj file into Netfabb, where it was stitched together and had its bottom cut off to ensure proper placement on the build plate. Equation: -4 * (g2*x^2 - y^2) * (g2*y^2 - z^2) * (g2*z^2 - x^2) + pow((x^2 + y^2 + z^2 - 1), 2) * 6 = 3 / 10 In the range of [-1.5:1.5] along all axes, and g2 is the Golden Ratio squared. Beyond this range, additional features emerge on the isosurface, but it becomes non-closed.
