For this assignment I modelled glasses in CAD and then 3D printed them. Glasses are a great thing to 3D print, because the frames have a subtle curvature that cannot be laser cut, and there are hinges that cannot be easily fabricated with other methods. I started this assignment by measuring existing frames, and then modelling them to scale in Autodesk Fusion 360. I followed the requirements laid out, including not making anything too thin, and leaving space between the hinge and the glasses arm so that the hinge worked. However, upon printing, the hinges were a bit too small and did not end up working.

I learned how to use the Fortus printer and the software in the wetlab to print my stl file. My final product turned out quite well after printing on the Fortus, with the exception of the hinges. If I had more time, I would consider printing on the Objet high resolution printer after changing the hinges, to have a high quality pair of glasses.

I made the dimensions work so that I could use clip-ons with the frames. They fit nicely!

Enthusiasm about the final product! The following show my CAD models. notice the subtle curvature of the frame side. I used the mirror function to get symmetry in the model, and projected a drawing onto a curved extrusion to get the frame curvature right to match my face. I was not there when the product finished printing, so a lab technician put them in the wet bath to remove the supports, I believe. I would like to learn this process the next time I print.
