For my capstone project, we were required to set up a budget and track the changes as we have to purchase material. One of our costliest materials is a resin used to 3D print the material that our final product will be made of. In theory it costs about $700. We had set up a goal to be below $1000. The school ended up having some sort of contract with the manufacturer that we had to buy the resin from and they cut us a deal and it ended up being half the price. In the end, we ended up being at $600 as opposed to $1000 which was quite a bit of saving.
