The Earrings |
|
|
|
The brief was to design
and cast a special gift for Valentines Day. We decide on a pair of heart
shaped earrings in 18ct gold with diamonds set in white gold. These were
to be presented in a cast box in 18ct gold, also set with a diamond.

| One of the benefits of Computer Aided Design, is the ability to create complex 3-dimensional forms that appear to be quite large in mass but being able to accurately control the dimensions of say, the wall thickness, we can keep the volume of the model to a minimum. |
|
| The CAD files were then converted into an STL format, this converts the surface of the models into a group of tiny triangles to enable the wax reproduction to take place. In this case the wax patterns were produced using a Sanders Rapid Prototyping process, (basically, the machine builds up layers of wax on a bed to produce the model). The waxes were then trimmed, sprued, invested and cast using the lost wax casting process. |
