Connexion with the environment
In order to identify PLA users and people interested in this new methodology, we talked with several institutions and representatives. Since the idea of our project had born talking with the Fab Lab of the University of Chile, as mentioned in the project time line (hyperlink), we presented our project to the director of the Fab Lab, who wrote us a letter of inquiry (download here ****FALTA).
We also went to talk with Andres Briceño, co-founder of the Santiago Fab Lab, to make our project cross the frontier of the University and see if there was a real need or interest for biological PLA.
There, we discovered other ways to use PLA, since in this Fab Lab they combine PLA with other biodegradable materials such as wood to make composite materials and help the technology to reach the market. Indeed, if PLA is quite used to build prototypes, product designers don’t like working with it because plastic products are not as attractive as wood products, for instance. So the idea of mixing PLA with a more “esthetical” material such as wood allows a friendly design for many objects, which makes composite PLA a good candidate for new 3D-printed products. Moreover, composite PLA can have better mechanical properties than PLA according to the material it is mixed with, and can last more than 2 years without losing its biodegradable properties, which allows a wider range of uses.
When we presented our project, Andres Briceño agreed that although costs can vary a lot according to the country of origin, it is expensive to buy PLA. He added that if we could demonstrate our fabrication process is cheaper than the current ones, the project would turn very attractive for many digital fabrication laboratories, for he gave us his support at the end of the visit, signing us another letter of inquiry (download here).
In parallel, we tried to connect our project with the environmental problematic, looking for an institutional support to evaluate the potential of biological PLA. We reached the Government through the Ministry of the Environment, which manifested its interest through a letter of inquiry (download here), in which it recognizes the importance of “the fabrication of biodegradable materials which implies fewer possible impacts on the environment”.
In order to evaluate those impacts, the positive and negatives ones, we met with Claudia Mac Lean, in charge of the Sustainability Office of the Faculty. She offered us to present our project to her pupils in the context of a Sustainable Project Workshop and to help us with an analysis of impacts through the Life Cycle Assessment methodology. And here we are.
