What did one eye say to the other eye? “Between you and me, something smells!”
So here goes, another post. Strap on those chaps and hold tight we’re going on a bumpy ride.
For this project, we were tasked with finding a professor crazy enough to let us 3d print them something. I just so happened to ask my Neuropsych professor John Sparrow if he would like an eye model. After thoroughly licking his face with his lizard tongue he happily agreed. You see, Professor Sparrow is actually a lizard from outer space wearing a man’s skin because he feeds off the tears of college students. At least, after taking his stats class, this is what I have come to believe. Prove me wrong.
This project was challenging in a number of ways, mainly because I procrastinated, but also because I started the project by trying to be all FANCY and using sculptris. If you haven’t heard of sculptris is a sculpting modeling program that basically gives you a blob of clay that you push and pull to form models. It’s awesome and it’s free. Check it out if you haven’t yet.
Anyway, after spending more time than I should have not only learning a new program but also modeling a darn eye
with all the muscles I realized sculptris was cool but was NOT going to do what I needed it to do. Not without making it more complicated than necessary. So restart I did.
I started with a rough sketch of an eyeball model that I drew in a vector-based drawing program called Mischief. It has an endless canvas, and again, I highly recommend it if you haven’t checked it out yet.
The next step was to start getting all my splines and sketches to become a reality.
As you can see here, I’m roughly following my sketch so that it can be revolved 180 degrees to make one half of my eyeball.
Here is what it looked like after I revolved all of the sketches.
From here I changed the appearance of the outer eye, the cornea and the lens.
I then added the rectus and oblique muscles on the outside of the eye and colored them red. I then added the optic nerve to other side.
Here you can see that I added a small cut away so that it could be painted to show the choroid layer of the eye, which is below the sclera.
Since I have a personal printer at home I decided to print this with my Anycubic photon. It is a DLP printer that uses UV curing resin as opposed to PLA filament.
