Stereolithography Models

Stereolithography is one of a set of engineering technologies called Rapid Prototyping. Rapid prototyping allows the fabrication of physical replicas of 3D computer generated models in a layered approach. After the generation of a 3D rendition, software slices the file from top to bottom and then the slice data is sent to a machine that fabricates the part slice by slice. The technology is mainly used for engineering purposes for the quick fabrication of design parts for physical analyses, form, fit and functional testing before full scale fabrication. The slice by slice fabrication technique found a strong marriage with the Computed Tomography data for fabrication of anatomic structures (Biomodels)


Stereolithography in specific fabricates parts from a vat of photo-curing polymer using a computer guided UV laser. The UV laser moves scans the curing polymer, fusing the selected layer onto a platform. The platform then shifts down the thickness of one slice and the laser sweeps the second layer. Thenprocess is repeated many times until the part is built from bottom to top. Slice thickness vary from 0.15mm-0.05mm (higher slice resolution than CT, which varies from 0.1mm-3mm). The most commonly used resins in medical applications is the stereocol resin, which is medical grade resin that is FDA class VI approved for sterilization and use in the operating room.
