Hello!
My name is Ozkan Cil I am a biology teacher and its my first year teaching. I had a few questions, first off where can I download 3D printable models to print for free, or even buy them? Secondly, is it possible to find sponsors who would be willing to donate 3D machines to the school?

You can find a lot of 3d printable models in thingiverse.com.

I checked it out and its great thank you!

As some people are saying, thingiverse is a great website for free models, as well as yeggi.com, which is similar, but yeggi takes models from all websites, free or paid. If it is your first time with 3D printing, I would recommend thingiverse, and yeggi is my second choice.

While I do not know for sure of any companies who would give you a free machine, there are many companies that would give you a discount as long as you can provide proof that you are buying for a school environment. You can contact the support of whatever company you want to purchase printers from, and ask them what kinds of educational discounts or promotions/bonuses they have.

Even if you do not do that, there are many budget 3D printers that work great, and cost under $1,000. Some even cost under $500. If you do some research, I am sure that you will be able to find the printer that works for you.

BTW, a great website for a basic comparison of 3D printers is 3D Printer Comparison Chart. I occasionally look at it whenever i want to see how some printers compare against others.

I wish you the best of luck in finding a printer that works for you, as well as good luck in your first year teaching.
