an Investigation of Additive Process 

This project aims to investigate additive processes which alter form and material attributes through deposition techniques. With the small Kuka robot as the primary machine, we move from 2D operations into 3D processes. The goal is not only considering tool path but coordinating change in material attributes. Therefore, the sequence of building, as well as the timing and switch in the material composition are important factors in this project. According to the statement above, I try to create an intricate path for the extruder. By the fractal algorithm, I produce a set of fractal polygons, then rotate them with different angles. Finally, through loft operation, I can get a vessel with numerous folding surfaces. Based on this form, the tool path will be produced by continuous contouring. For the purpose of achieving the relationship between opacity and translucency, shifting materials is a necessary method. The material deposition will together create patterns. Utilizing two kinds of PETG: clear and black, the feature of surfaces could be showed obviously. In order to create a gradient from clear to black, I segment the black PETG into many small pieces and insert them into the extruder orderly. When the clear ones are still in the extruder, the black segments will blend with them together. It results in different shades of black and translucent purple. Because of material attributes, the effect of light and shadow is fascinating. Through the folding surface, the light will be refracted into different colors. This effect is just like the light gleams from cosmos or aurora.
