ASME Student Challenge: Engineer a Personal Water Purification System

Medium

Water pollution is a serious problem in many areas of Brazil and particularly in Sao Paolo and Rio de Janeiro. The majority of waste water is left untreated with an increasing amount of refuse, sewage and other contaminants flowing directly in to rivers, streams and the ocean.

Your challenge is to create a 3D printable personal water purification system for a household in Brazil. It would be used to treat drinking, washing or bathing water.

With the many new 3D printing manufacturing techniques, there are no restrictions on part manufacturability. This opens up a new world for organic and complex part shapes that could not be machined or molded from plastic with traditional manufacturing methods. Additionally, designs that had to be created as multiple parts for traditional manufacturing purposes can now be single parts that can be 3D printed.

With new generative design technology there is an easy way to optimize and transform traditional designs or otherwise prismatic parts into beautiful, unique and functional components. Optimization is also a way to reduce the strain on the environment by using less material and producing less waste.

Your final design should contain at least one (1) component that can ONLY be manufactured using 3D printing.

Extra credits will be given to designs that are also optimized to save material without compromising integrity.

The winning designs will be on display, courtesy of Stratasys, at E-Fest South America on July 29, 2018 at UFRJ in Rio de Janeiro, Brazil.

    I feel like the design should be open to non current students. Recent grads like myself might be happy to participate without prize eligibility. Honorable mention possibly.

    the challenge is about treating the bathing and washing water for household use or is it about making them clean enough to drink?

    What is the exact purpose? Reduce releases to the wild or provide water for human consumption?

    @Ravi preferably it would be drinkable, but the water should be usable for bathing and washing as well.

    @Jace - Yes Highschoolers are allowed to enter, but you will need to have a parent/guardian/teacher help in the submission of your entry.

    @matt Hi Matt, I've noticed in the comments that you have had some doubts regarding my design, I just want to clarify that I have made all the parts in Solidedge and I am willing to upload the files if needed the only reason I am not uploading it is that I am afraid editing the model after uploading is going to disqualify me. The reason the parts are featureless is because I have scaled down to model to make the dimensions more reasonable. And about the generative design. I have used generative design as can be seen in the pics uploaded (pic showing the generative design and the mass percentage loss) . But I couldn't incoperate the design into my model as I downloaded the solidedge version from the link provided and Ive noticed everytime I tried to use it in my design the design used to go and mating of parts couldn't be done. I googled and researched alot and found out that some features were suppressed in my version of Solidedge and that included generative design. I made another part and traced my generative design obtained on it to receive a part that was as close as possible to the generative design. While I haven't directly used generative design I have based my the part of it and have used it as can be seen from the pictures. I am also ready to upload the original unscaled files if needed. I understand your concerns regarding the design. I hope you take this into consideration. I don't want to lose points for scaling my part down as I have worked very hard learning the new software. Thank you
