...become possible owing to advances in the quality of the output produced by machines originally designed for RP (Figure 2). Many parts are now in fact produced in a fully functional, final state and are therefore not prototypes, despite being produced using machines recognisable as rapid prototypers. [Described image] Figure 2 Example of a latest-generation (in 2015) rapid...

...becomes r sub 12 times r hat sub 12 equals bold r sub one minus bold r sub two full stop Equation label: (7) This notation is convenient because the indices 1 and 2 are in the same order on both sides of the equation. However, remember that the displacement is from q sub two to q sub one . The left-hand index labels the end-point and the right-hand index labels the...
