Designing
To bring our ideas to life and transform them into tangible designs, we first made a rough sketch and then utilized computer-aided design (CAD) software to design the sketch into a 3D model. CAD provided us with a powerful platform for which to digitally visualize and model our mini liquid tree device. It allowed us to create detailed and precise three-dimensional representations of our design concept. This virtual prototype helped reduce time and material waste, enabling us to optimize the design's performance and functionality before moving to the production stage.
Manufacturing
Creating a working prototype of a mini liquid tree device involved the innovative use of laser cutting and 3D printing technologies. In the case of the mini liquid tree, we cut acrylic sheets using a laser cutter. After laser cutting each individual component, they were then carefully assembled to form the skeleton of the mini liquid tree. Waterproof silicone caulk was used to securely join the pieces together and prevent any water leakage. A filter and slits were also integrated into the lid design, allowing for microalgae to breathe and photosynthesize, while simultaneously preventing water loss. This combination of laser cutting and 3D printing enabled the creation of our captivating and functional prototype that demonstrates the potential of microalgae in environmental sustainability.
Experimenting
Our culturing process began by creating an ideal environment for the microalgae to thrive, which involved setting up a cultivation system that provided the necessary conditions for optimal growth. For example, adequate light, temperature, pH levels, etc. We added an initial inoculum of microalgae (our seed population), which multiplied and expanded over time, as is visible in the video. As this continued to proliferate, it formed a dense biomass that gave rise to a vivid green liquid.
First Prototype
The Tree10 mini liquid tree device serves both aesthetic and functional purposes. It showcases the incredible potential of microalgae to mitigate carbon dioxide levels, improve air quality, and contribute to a sustainable future. Moreover, the process of culturing microalgae for this purpose highlights the versatility and adaptability of these organisms in various biotechnological applications. For this application, the microalgae biomass inside the device acts as a living filter, absorbing carbon dioxide and releasing oxygen through photosynthesis.
Overall, culturing microalgae to create a mini liquid tree combines scientific ingenuity, environmental consciousness, and artistic expression, demonstrating the interconnectedness between nature and technology.
Second Prototype
The second prototype of our Tree10 device includes improvements through feedback. Some of our changes impact the product's sustainability, efficiency, visual aesthetic, structural stability, modularity, and it's maintenance ability
