Abstract
The authors describe the novel use of a selective laser sintering (SLS) machine, commonly used in the aerospace industry, to produce an accurate model of an orbital blowout fracture. Standard stereolithographic apparatus (SLA) technology failed to reproduce either orbital floor of a patient with a blowout fracture. The use of SLS technology using the same CT dataset to produce a superior model, highlights potential limitations of routine SLA technology and the high accuracy of SLS models. A custom-made titanium implant was constructed by hand using the SLS model as a template, it was positioned surgically and the patient's symptoms resolved uneventfully.
