Repeatable quality and a reduction in
the amount of tolerance.
Modelling wax, high-density foam,
manufactured board and card.
Consider health and safety, tooling, feed
speed and surface finish.
Modelling wax can be machined by
CNC and then used to produce a
master for lost wax casting.
Consider feed speed, depth of cut,
coolant and tooling.
Changes of colour and texture give a
better aesthetic view of what a product
may look like.
