Designing in the Computer

Until a few years ago, designing 3D models involved computer-aided drafting (CAD) software (such as Autodesk Revit, shown in Figure 5-3) that required powerful computers and expensive specialized software. For years, CAD was well beyond the capabilities of most people outside of a dedicated group of specialists.

Additive manufacturing allows the creation of complex internal structures rather than simple, solid-block components — an improvement over traditional CAD tools which cannot always create models to rival the true capabilities of 3D printers. New tools are becoming available in specific arenas, as in the case of medical implants that must be highly customized to fit an individual's bone structure while also allowing complex lattices and other forms of fabricated non-solid models. (Figure 5-4 illustrates a complex structural lattice applied to what was originally just a hollow sphere with sliced-off sides.)
