summary	This project explores the advantages of employing continuum material topology optimization in a 3D non-standard lattice structure through fiber additive manufacturing processes (Figure 1). Additive manufacturing (AM) has gained rapid adoption in architecture, engineering, and construction (AEC). However, existing optimization techniques often overlook the mechanical anisotropy of AM processes, resulting in suboptimal structural properties, with a focus on layer-by-layer or planar processes. Materials, processes, and techniques considering anisotropy behavior (Kwon et al. 2018) could enhance structural performance (Xie 2022). Research on 3D printing materials with high anisotropy is limited (Eichenhofer et al. 2017), but it holds potential benefits (Liu et al. 2018). Spatial lattices, such as space frames, maximize structural efficiency by enhancing flexural rigidity and load-bearing capacity using minimal material (Woods et al. 2016). From a structural design perspective, specific non-standard lattice geometries offer great potential for reducing material usage, leading to lightweight load-bearing structures (Shelton 2017). The flexibility and freedom of shape inherent to AM offers the possibility to create aggregated continuous truss-like elements with custom topologies.

title	Design Driven Physical Experimentation: A flexible wind sensing platform for architects
doi	https://doi.org/10.52842/conf.caadria.2016.239
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 239-248
summary	Architectural design in this ‘digital age’ is becoming more embedded within virtual computer aided design environments. This study expands this virtual design environment back into physical realms through the use of microelectronic wind sensing technology. An interactive and flexible wind sensing system (open source minia- ture portable wind tunnel and wind sensors) was evaluated for its abil- ity to simulate and measure the effects of wind. Physical models of four high-rise buildings were constructed to evaluate ground level pe- destrian comfort resulting from the degree of torsional twist in the building form. The model investigation formed a case study for evalu- ating of the low-cost miniature portable wind tunnel and microelec- tronic wind sensing system for comparison with an industrial aeronau- tical wind tunnel and high precision wind sensors.

title	Complex human auditory perception and simulated sound performance prediction
doi	https://doi.org/10.52842/conf.caadria.2016.631
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 631-640
summary	This paper reports an investigation into the degree of con- sistency between three different methods of sound performance evalu- ation through studying the performance of a built project as a case study. The non-controlled office environment with natural human speech as a source was selected for the subjective experiment and ODEON room acoustics modelling software was applied for digital simulation. The results indicate that although each participant may in- terpret and perceive sound in a particular way, the simulation can pre- dict this complexity to some extent to help architects in designing acoustically better spaces. Also the results imply that architects can make valid comparative evaluations of their designs in an architectur- ally intuitive way, using architectural language. The research acknowledges that complicated engineering approaches to subjective analysis and to controlling the test environment and participants is dif- ficult for architects to comprehend and implement.

title	Breathing skins for wind modulation through morphology
doi	https://doi.org/10.52842/conf.caadria.2016.219
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 219-228
summary	This study aims to investigate the design power to manipu- late the behaviour and characteristics of air through geometrical ma- nipulation of building skins. The simple cubic cells in the global sys- tem of a porous screen were manipulated to investigate the impacts of screen’s morphology on the air movement pattern within and around it. The results we discovered from the evaluation of several screen systems revealed trends in response to the careful manipulation of ef- fective shape parameters within a designed matrix of variations as a Matrix of Possible Effective Typologies (MPET). In this research, the main principles of framing the initial matrix were based on: a) Creat- ing pressure differences across the screens as a result of surface intru- sion and extrusion compositions. b) Changing the nature of the airflow (velocity and turbulence variation) with geometrical manipulations of the inlet and outlet of the screens’ components. Experimental and nu- merical studies were undertaken in parallel including the use of a wind tunnel with very smooth flow with precision wind sensors and the numerical studies by Computational Fluid Dynamics. The aim of this paper is to present part of the empirical investigations to demonstrate the power of geometry in shaping the air patterns, altering pressure and velocity through geometrical modification of porous surfaces for future applications.

title	Workmanship of Risk: continuous designing in digital fabrication
doi	https://doi.org/10.52842/conf.caadria.2016.651
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 651-660
summary	Research projects exploring the realm of digital fabrication have shifted in recent years from developing novel techniques and outcomes to the development of tools that are part of the design pro- cess. The alignment of material systems with digital fabrication tech- nology and tooling processes have led to new terminology such as ‘digital craft’ and ‘digital making’; both terms imply a relationship be- tween craft and digital design and fabrication. Also implied is an inti- mate relationship between material production, digital tools and CNC fabrication techniques; critical ingredients in contemporary design processes. David Pye’s concept of ‘the workmanship of risk’ is used extensively in current discourse as a means to qualify digital fabrica- tion as craft production. This reading of digital fabrication as craft is limited because the word craft is used as an analogy to draw parallels between craft production and digital fabrication. There is a gap in the knowledge of what contemporary craft practice can bring to digital fabrication as a discourse or more precisely, the mechanism that al- lows digital fabrication projects to be read as a form of craft practice. This paper suggests that craft practice is rooted in the relationship be- tween material, tools and technique as an intricate workflow within a project; quantifying risk is just a means to assess this relationship. The workflow however can be considered as autopoietic in nature; it is both self-referential and self-making at the same time as continuously designing.
