  1. PARAMETRIC MODELING OF THE SCHLEMM’S CANAL USING FUSED DEPOSITION Mallory Westphal, Winston Sealy, Automotive and Manufacturing Engineering Technology Department, Minnesota State University, Mankato, 205 Trafton East, Mankato, MN 56001 The purpose of the research is to produce a model of Schlemm’s Canal using Fused Deposition Modeling (FDM). Current research being conducted at the Mayo Clinic in conjunction with Dr. Bentley, Biology Sciences department, Minnesota State, Mankato, requires modeling the eye’s Schlemm’s Canal. This research is being performed to explore relationships between Glaucoma and clogging of the Schlemm’s Canal. Glaucoma is an eye condition that can lead to permanent nerve damage in the eye resulting in blindness if it is untreated. Producing a model of a cross section of the eye, emphasizing the Schlemm’s Canal will further aid researchers in better visualizing the effects on the Schlemm’s Canal. Therefore, FDM, an additive manufacturing process will be utilized for modeling and prototyping. As a result of the layering process of FDM, a 3-Dimensional (3D) cross section model of the Schlemm’s Canal will be created. Images of the Schlemm’s Canal tissue generated by Microscopic Computed-Tomography (Micro-CT) will be translated into a Stereolithography (STL) file format for modeling. The STL format converts geometries into tessellated meshes. The FDM process begins by slicing the tessellated model. A thermoplastic polymer is then extruded to construct the model layer by layer. The printed model is treated to remove support and residual material. The finished model will then be inspected to determine if there are any changes or improvements that need to be made to the STL file for a better cross section model.
