The multiple surface finishing techniques of painting, mirror polishing, silk-screening and UV coating for the prototypes required not only excellent surface finishing capabilities and experience, also the strong attention to each detail that would considerably affect the final finishing quality.
CNC Machining Prototyping:
CNC machining the top and bottom covers made of clear acrylic (PMMA) that would be mirror polished and UV coated. The smooth milled surface helped reduce hand polishing time also get tight tolerance. In addition, the cutting feed and speed of milling acrylic were different to milling the other plastics since its material properties of high brittleness.
