6.96 Model of one of the samples supported by the crate. Case studies 251 contour-based formats can be dramatically more effi cient. However, current stereolithography users have no functions within the preparation software (3D Lightyear TM ) for the verifi cation, translation and orientation or crucially support generation of contour formats, specifi cally the SLC. This is despite the fact that the necessary code for each of these functions exists elsewhere (C-Sup, VerSLC). These problems meant that to successfully build these models necessitated the utilisation and combination of several different pieces of software where appropriate and a thorough understanding of the stereolithography process. Objects that appear unfeasible for the standard practices of STL fi le and automatic support generation may in fact be perfectly possible if they are considered carefully (there is always more than one way around a problem). For example, these models were made possible because (1) the nature of the objects suggested that they would form self-supporting and self-draining structures in the inner volume and (2) the SLC fi le format was used.
252 Medical modelling 6.97 Final cleaned model of one of the samples. As building these models has shown, seemingly obsolete software may still posses a level of accessibility that is extremely useful to the expert user, especially in research. Consequently, for many researchers in this fi eld it is advisable to maintain copies of superseded RP software. 6.15.8 Software • C-Sup – a module of Mimics Version 7.0, Materialise NV, Technologielaan 15, 3001 Leuven, Belgium, 2001. • 3D Lightyear TM version 1.1 – Advanced User License, 3D Systems Inc., 26081 Avenue Hall, Valencia, CA 91355, USA, 2000. • VerSLC, 3D Systems Inc., 26081 Avenue Hall, Valencia, CA 91355, USA, 1993. • Maestro version 1.9.1, 3D Systems Inc., 26081 Avenue Hall, Valencia, CA 91355, USA, 1996. • Slicer – a module of Magics version 6.3, Materialise NV, Technologielaan 15, 3001 Leuven, Belgium, 2000.
