summary	With supply chain issues and rising price of construction materials, mycelium can potentially provide reliable, eco-friendly and sustainable alternatives to traditional construction materials as substrates used for growing mycelium can contain almost any recycled cellulose: sawdust, used coffee grounds or paper. Characteristics of the final product are determined by substrate, mushroom species, the time of growth and further treatment of mycelium (e.g. high pressure forming). In this paper we describe semestral work of both students and tutors of an Experimental studio, focused on additive manufacturing together with rather novel sustainable materials. Students’ semestral task was to find use cases for mycelium as a building element. As a part of the assessment they were tasked to come up with use cases, designs, manufacturing methods and finally build a mock-up model in 1:5 scale. Students intuitively started with the combination of digital modelling plus digital fabrication. In the end they finished with manufacturing the physical model traditionally, where they had to react to the change of the visual outcome of the model. Firstly, we present the students’ solution for the mycelium material used in their model, next, we describe our observation of the whole process of letting students go through “learning by doing” research, Finally, we present lessons learned in this experiment.

title	Strengthened Shells: Possibilities of conformal printing on curved surfaces in large scale 3D printing
doi	https://doi.org/10.52842/conf.ecaade.2024.1.009
source	Kontovourkis, O, Phocas, MC and Wurzer, G (eds.), Data-Driven Intelligence - Proceedings of the 42nd Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2024), Nicosia, 11-13 September 2024, Volume 1, pp. 9–16
summary	This paper investigates the potential impact of conformal filament layering on various 3D printed structures with the aim of enhancing or altering their properties. Currently, large scale 3D printed objects predominantly utilize vase-mode style prints, occasionally featuring more intricate internal structures resembling FDM infill patterns, yet typically produced in a single continuous extrusion, resulting in a single perimeter wall thickness. This research seeks to explore the advantages of layering additional material onto the outer perimeter of a print, leveraging the capabilities of 6-axis robots and conformal printing techniques. To empirically assess the efficacy of this technique, an experiment is designed involving the fabrication of a consistent one-layer domed shell on a supportive form, onto which additional layers, oriented differently and featuring various patterns, are subsequently applied. The resultant samples are subjected to tests measuring both their strength and visual attributes, generating data for further analysis and application.

title	Non-planar 3D Printing of Clay Columns
doi	https://doi.org/10.52842/conf.ecaade.2024.1.167
source	Kontovourkis, O, Phocas, MC and Wurzer, G (eds.), Data-Driven Intelligence - Proceedings of the 42nd Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2024), Nicosia, 11-13 September 2024, Volume 1, pp. 167–174
summary	The contemporary landscape of construction 3D printing of materials like clay or concrete mainly relies on planar slicing, which, regrettably, impose constraints on the realization of overhangs and cantilevered structures, thereby limiting architectural design flexibility and posing issues in fabricating intricate structures. In response to this challenge, we investigate the integration of non-planar slicing in the construction printing of structures featuring substantial overhangs. We present a novel approach to crafting print paths strategically, fragmenting the global overhang into discrete local segments. Additionally, we introduce self-balancing control to help the buildability within segments of the print path, elevating the stability of the freshly deposited concrete during the printing process. Our methodology redistributes a portion of the bending forces into tension forces oriented along the print path, thereby augmenting the structural integrity and buildability of intricate structures with overhangs and vaults. The efficacy of our method is demonstrated through a computational parametric model and a physical prototype. A comprehensive comparative analysis is conducted against conventional planar printing methods, encompassing metrics such as geometric accuracy, buildability, material efficiency, and print time.
