2.  Warping  Stable  Porous  Uniform grain structure.

3.  Quality of finish  Tool wear  Expansion.

4.  Consider… › Initial investment › Training › Working environment › Flexibility › Communication › Wastage.

5.  Repeatable quality and a reduction in the amount of tolerance.

6.  Modelling wax, high-density foam, manufactured board and card.

7.  Consider health and safety, tooling, feed speed and surface finish.

8.  Modelling wax can be machined by CNC and then used to produce a master for lost wax casting.

9.  Consider feed speed, depth of cut, coolant and tooling.

10.  Changes of colour and texture give a better aesthetic view of what a product may look like.
