After some research I decided that with my budget there was no way I could build a metal 3D printer. Because of this I decided to focus on an interesting design that uses a liquid plastic resin that solidifies with UV radiation. My first design is a machine that houses a 100 mw ultraviolet laser and can move it upon a two dimensional plain. Then I will put a small nozzle underneath the laser that will slowly release the resin into the printer. The laser will be pointing at the resin directly after it is released so in theory it should harden in place and form a solid object. There is also another design that I like that might be simpler. This design involves having a UV lamp in the top of the printer and a nozzle that moves in 3 dimensions. This idea seems easier to me because there is no need for me to match the laser movement to the nozzle movement. There is one more design that may work for this machine. This is the simplest design because it works by slowly building the shape of the creation by adding a single layer of plastic resin then hardening it into a thin slice of the object you are making. After this layer is hardened more resin is put in the chamber and more of the resin is hardened into shape.
