These computer files are used to create 3D animations depicting the events surrounding a product failure or other situation. Stereolithography adds another, real world, dimension to the presentation of evidence. The same information used in creating the animation can be used to create complimentary 3D models for use as exhibits in trial. An effective presentation can now include video and or animation or the events, enhanced by a physical model used to isolate important areas for further discussion with expert witnesses, and to educate and persuade the jury. The cost is greatly affected by the subject and its complexity.
Costs can range from a few hundred dollars to a few thousand.
The relatively low cost puts stereolithography models in the same category as large poster exhibits used every day in trials throughout the country. The process clearly breaks the 2D to 3D barrier for presentation of evidence. Paul Kakert is President of Forensic Media, a multimedia company specializing in forensic presentations and 3D animation.
