The bioDigital matter research group at the department of Architecture and Built Environment at Lund University is today opening the exhibition bioDigital Futures at Time Space Existence, a part of the Venice Architecture Biennale 2021, hosted by the European Cultural Centre.
The exhibition explores the future of 3d printing in architecture. How can this technology be used to create buildings that are more sustainable, deliver improved functionality, and lead to better architecture? At a time when construction 3d printing is entering the public discourse, it is more important than ever to reflect on the far reaching consequences of this revolutionary technology, and challenge the assumptions we make based on past technologies.
The exhibition features two large scale prototypes, Protomycokion and Meristem Wall.
Protomycokion is a column 3d printed from a wood-fungus biocomposite. It is made from forestry by-products and a living fungus. The mycelium grows through the printed object, strengthening it and turning it water-repelling. By harnessing the power of microbiological processes, a true circular construction process becomes possible.
In order to mediate the complex requirements of the fungus organism, the printing process, and the final use as an architectural element, the column is designed using a series of computational simulations and algorithms.
Meristem Wall is a prototype of a fully 3d printed building envelope. It is made using sand binder jetting by Voxeljet and Sandhelden, complemented by a custom CNC knitted fabric developed and fabricated in collaboration with Dr. Mariana Popescu of Block Research Group at ETH Zürich.
The wall incorporates a system of transient and controllable airflows modelled on the physiology of termite mounds. This mechanism allows the wall to act as a climate modulator, regulating, storing and controlling the building's internal climate.
The wall’s geometry and the integrated airflow enables it to function as a biological habitat for a diverse ecosystem, taking the concept of the green wall beyond a monocultural garden. It provides a rich habitat for urban wildlife, providing a range of ecological niches.
The wall is designed using an interdependent model that negotiates the space and relationship between a wide range of functions including utilities such as electric wiring, aesthetic preferences, structural performance, and bioclimatic considerations. This self-organising simulation is capable of creating unique compositions of space to fit a wide range of context and functional needs.
The exhibition and the projects featured are the work of PhD candidate Ana Goidea and Dr. David Andréen from Lund University, Department of Architecture and Built Environment.
