Creative Formation: CNC carving hand-sculpted representations
A rapid prototyping process for an ornamental component was developed by manipulating a digitally sculpted architectural surface. The enlarged surface texture of a trumpet flower was first finely rendered using graphite then digitalized; via height field extrusion, it is then turned into two substrates: one for thermo-forming using CNC milling with foam, another for silicone molding by means of plaster 3D printing. Positive casting using plaster/ other cementitious materials finds its potential application in ceramic tile making, whereas the low-cost and efficient vacuum-forming process lends itself to lighting fixture (e.g. wall sconces) production.
