Our purpose is that to make a third dimension and unique project to improve human awareness of the dangers of air pollution. The air pollution is the significant issue in particular countries, which also is a big challenge to solve this problem in the world. In fact, if the public and government focus this issue it might reduce a lot. For those reasons, we decide to produce something to educate people. According to our research the air pollution harm to our lung and affect our health. Therefore, we thought how to make the public to pay attention to air pollution. Initially, We thought to make a video to educate people, but there were many examples on the Internet, and it might drive people annoying. We considered an ideal concept, which makes people to be attracted our work and direct-view. Then we decide to use 3D model and into LEDs to present our work because 3D is more intuitive than 2D. It is easy to make people understand our design and affect people's motivation. The LEDs will imitate human breath that gives people some sense of substitution. We want to audience imagine that this is their lung. Also, we try to make smoke and smoke sensor to lead our work interaction, but there is the particular issue such as we have no more time, no enough budget and the university build has smoke sensors, so we decided to cancel this idea. Besides, We added two buttons to connect the wires that each button can control half lung of LEDs as our team devised that it is better to make the design interactive. We need to add LEDs inside of the lung, so we have to separate the lung and print part of a lung. It made few issues in our model mainly connection. We also spent a lot of time to make the 3D model because we did fail prototype, which is no connection part and wrong size, so we have no enough experience to make the final one. Also, many people were waiting for 3D printing in 3D Lab, and it probably spends one more week to print. At begin, the locks which look like teeth and it helps our model to connect each part together. However, the teeth do not match the gap; I think because in the software there is the exactly same size and when 3D printing machine print out the teeth, there are tiny different about teeth and gap. Then we try to use the sandpaper to make the teeth smaller, but the material of 3D printing is empty inside, and we broke the teeth. We decided to reprint our part of the model, which was broken. However, if we reproduce the whole model, it will cost a lot of money and time. Someone advised us to use the magnet to link the each part of the lung; then we drew some holes and put some magnets into the holes, but it not works, which are not strong enough to connect each part. Finally, the 3d lab stuff gives the suggestion for us that only print piece of the lung include teeth. It can reduce the time, and we do not need to pay. Then I glued it to the lung and sprayed the whole lung again. Fortunately, it looks perfect and quite useful. In final analyze, our project is direct-view and meaningful but the purpose of our project is not integrated, and our solution is not direct to solve this problem. Also, the weak point of our project is not enough interactive because we fail some staffs and no enough budget and time. The whole processing we have gained how to solve the problem, and sometimes we try many times for the solution because not all the solution is appropriate. In addition, we have learnt using Rhinoceros to make 3D model, which we spent three weeks to watch videos (RHINO TUTORIALS) and practice and I thought improve lot about this software and 3D printing.
