“…Their composition is based on a water medium, a binder and reinforcing cellulose fibres (Rech et al, 2022). Bio-composite materials for additive manufacturing have a slurry viscosity when mixed and can be graded by varying ingredients which gives the material different properties (Chiujdea and Nicholas, 2020); (Dritsas et al, 2019). After fabrication, the prints undergo a curing stage.…”

In this paper, we describe an automated remote monitoring system to uncover the impact of environmental phenomena on 3D printed bio-polymers behaviour and lifespan. The novel fully automated in-service framework allows for long-term monitoring with a wide range of wired and optical sensors and to correlate and analyse the gathered data. A focus is set on non-invasive measurements with Computer Vision technology. Here we introduce a computational image pipeline that allows for automated analysis and feedback on monitored bio-composite samples and assemblies. The framework is easily deployable, cloud-based, and accessible remotely. We evaluate the function and reliability of the framework in two design cases indoors and outdoors and gather insight for future practice with bio-based materials on both design and in-service levels.

Due to their ability to store carbon during growth, biomaterials are currently gaining attention in the construction sector to produce alternative building bio-components. Bio-residues in particular are quite promising, as applying them in construction might enhance strategies of circular bio-based economy. However, despite many studies and few products already on the market, a clear classification of bio-residues has not been available yet, and the experiences related to construction applications are scattered and fragmented. Hence, this paper offers a comprehensive framework by visualizing the production flows from bio-residues to building components. It operates a review of contemporary bio-manufacturing processes by classifying them based on their primary bio-sources, and it provides critical knowledge of their advancements, by displaying both established and emerging possibilities. By doing so, the study identifies lower energy-intensive applications, involving the direct transformation of fibrous agricultural materials into insulation building products, and more complex processes encompassing the extraction of intermediary bio-products, such as cellulose, and polymeric biocomposite. These last are starting points for promising technologies like electrospinning and additive manufacturing, with disruptive potential in manufacturing advancement. Indeed, the research highlights future research directions and initiates a potential tool to aid stakeholders in decision-making for a more sustainable built environment.

Urban development and the construction industry account for a considerable proportion of global carbon dioxide (CO2) emissions. Emerging biological materials, such as those proposed in this paper, seek to utilize the metabolic functions of living microorganisms to reduce some of the negative impacts of humans on the environment. The material explorations demonstrated in this paper propose a living photosynthetic carbon capture textile for the built environment. We demonstrate making practices that integrate living microorganisms within experimental methods of digital fabrication; specifically, harnessing photosynthetic microalgae that feed on waste and are capable of sequestering CO2 from internal building settings. These new biocomposites incorporate flexible textile substrates, i.e. cotton, hessian, polyester, and canvas, which provide a range of algae laden matrices that continue to develop and change during the useful part of the material’s lifecycle. This paper explores biological 3D printing fabrication processes and studies the development of mixtures that are compatible with the fabrication method and support microalgae (Chlorella vulgaris) metabolic processes. A range of incubation methods are assessed, highlighting the need for a support environment. The biocomposites’ performance is tested using imaging pulse amplitude modulation fluorometry (Imaging-PAM) to investigate changes in microalgae chlorophyll fluorescence over a 14 day period.
