Several direct metal fabrication technologies are available on the market for production of medical implants. Each technology has advantages and drawbacks and there is no consensus what constitutes optimal technology. These technologies are often considered to be competitors but that may not always be the case. Laser-based systems tend to be more accurate than electron beam-based systems and provide smaller features and finer surfaces. However, the fabrication cost may be higher and the build time longer with laser-based technology compared to electron beam-based technology, prohibiting fabrication of larger implants. This presentation reviews case studies where both electron beam and laser beam systems have been used to fabricate custom implants out of titanium. Build time, surface quality, feature size, and cost were compared and reviewed. This presentation gives an overview of the technologies and can help potential users to choose the system that fit their needs the best.
