Urban development and the construction industry account for a considerable proportion of global carbon dioxide (CO 2 ) 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 CO 2 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.

光合纺织品生物复合材料：使用实验室测试和数字制造来开发灵活的生活用建材

城市发展和建筑业在全球二氧化碳（CO 2）排放中占相当大的比例。新兴的生物材料，例如本文提出的材料，试图利用活微生物的代谢功能来减少人类对环境的某些负面影响。本文演示的材料探索提出了一种用于建筑环境的光合作用活性碳捕获纺织品。我们演示了将数字生物实验方法中的活微生物整合在一起的制作方法；特别是，利用以垃圾为食的光合作用微藻，并能够从建筑物内部隔离CO 2。这些新的生物复合材料结合了柔软的纺织品基材，例如棉，粗麻布，聚酯和帆布，它提供了一系列的藻类负载基质，这些基质在材料生命周期的有用部分中会不断发展和变化。本文探讨了生物3D打印制造工艺，并研究了与制造方法兼容并支持微藻（Chlorella vulgaris）代谢过程的混合物的开发。评估了各种孵化方法，强调了对支持环境的需求。使用成像脉冲幅度调制荧光法（Imaging-PAM）测试生物复合材料的性能，以研究14天时间内微藻叶绿素荧光的变化。本文探讨了生物3D打印制造工艺，并研究了与制造方法兼容并支持微藻（Chlorella vulgaris）代谢过程的混合物的开发。评估了各种孵化方法，强调了对支持环境的需求。使用成像脉冲幅度调制荧光法（Imaging-PAM）测试生物复合材料的性能，以研究14天时间内微藻叶绿素荧光的变化。本文探讨了生物3D打印制造工艺，并研究了与制造方法兼容并支持微藻（Chlorella vulgaris）代谢过程的混合物的开发。评估了各种孵化方法，强调了对支持环境的需求。使用成像脉冲幅度调制荧光法（Imaging-PAM）测试生物复合材料的性能，以研究14天时间内微藻叶绿素荧光的变化。
