Limitations of the 3D printer

For the first design, we are testing out the drying time of the plastic. we are thinking that if you have only a small connection with two pieces off of the base that the plastic will not dry enough and start to droop down. the second design we tested the size capability of the  printer. We are hearing about 3D printing body parts which can be pretty big. If you wanted to build a chair or something, you would be limited to only having to print out the pieces and not the whole chair as a whole. The last design will test the accuracy of the printer. If you needed a part to have exact dimensions on a small scale the printer. For zippers, the whole design relays on being lined up exactly on a small scale.
