On completion of your chosen 3D CAD model a test prototype can be produced. The assembly is taken and usually shelled and all internal detail and features removed.
Space models have many uses and can be used as a design aid, assist with packaging design, or production line evaluation just to name a few. A finished model can be of a basic finish, right through to fully finished, painted or coated depending upon requirements.
Alternatively hand sculpted or CNC foam models can be produced. Usually produced from low density foam the models are in many cases created prior to the generation of 3D CAD. T
The foam models can effectively be used to assess varying design iterations and are a very rudimentary form of test prototype which can be used to validate design’s initial draft.
