Utilizing Rhinocerous, with the grasshopper plug-in, develop a surface model that aggregates a solid 3 dimensional part – of your design. Consider not only the variation of the driving brep surface through the manipulation of control points, lines, etc, but also the variation of the part and the possible layering of multiple skin systems for greater depth and effect. Project should follow and expand on the techniques covered in class and blog.
Produce, either in whole or fragmented form a 3D print of your surface. In this process careful attention must be paid to constructing a well formed ‘water tight’ part that falls within the tolerances dictated by the chosen printing material (ABS plastic or gypsum.) As cost is always a factor with 3D printing – this assignment is more about exploring the potentials of variation in the invented system and having a successful demonstrative print – than producing an elaborate and expensive model. For all intents and purposes, consider this a trial run of a prototyping technology that may be utilized to a greater extent in the final project.
Five curves were lofted in the grasshopper definition with two attractor points near each quadrant of the surface. 2 variable components in an octagonal form were created and differentiated across surface according to area size.
