summary	The research presented in this paper is part of a larger, emerging body of research into large-scale 3D printing. The research attempts to develop a computational design method specifically for large-scale 3D printing of architecture. Influenced by the concept of Digital Materials, this research is situated within a critical discussion of what fundamentally constitutes a digital object and process. This requires a holistic understanding, taking into account both computational design and fabrication. The intrinsic constraints of the fabrication process are used as opportunities and generative drivers in the design process. The paper argues that a design method specifically for 3D printing should revolve around the question of how to organize toolpaths for the continuous addition or layering of material. Two case-study projects advance discrete methods as efficient ways to compute a continuous printing process. In contrast to continuous models, discrete models allow users to serialize problems and errors in toolpaths. This allows a local optimization of the structure, avoiding the use of global, computationally expensive, problem-solving algorithms. Both projects make use of a voxel-based approach, where a design is generated directly from the combination of thousands of serialized toolpath fragments. The understanding that serially repeated elements can be assembled into highly complex and heterogeneous structures has implications stretching beyond 3D printing. This combinatorial approach for example also becomes highly valuable for construction systems based on modularity and prefabrication.

title	Discrete Assembly and Digital Materials in Architecture

summary	The paper will discuss two projects which explore the territory of discrete or digital material organisations in an architectural context. Taking inspiration from the field of Digital Materials, this paper presents an approach to architectural design which is fundamentally "digital" - not just in the process but also in its physical organisation. The use of discrete and digital materials in architecture is argued for from both an architectonic point of view, as well as from efficiencies related to automation of construction. Experiments with robotic assembly are caught between on the one hand the desire to increase speed, and on the other hand increased complexity. This paper argues that robotic assembly on the scale of architecture is only feasible and scalable in the context of digital materials and discrete computation, which has a limited set of connectivity problems. The two projects are a first attempt to translate the concept of Digital Materials to the domain of architecture. The result is an architecture which is digital in its physical organisation. It demonstrates how differentiated, complex and heterogeneous spaces can be achieved with just serialised, discrete elements.

title	Objectile e o projeto paramétrico [Objectile and parametric design]

summary	The objectile was a concept developed by Deleuze and Cache in the 80s. It treats the object as a variable and anticipates the society of obsolescence, an inquiry about the contemporary life of the object (marketing, function, representation, modeling, production and consumption). This concept deals with the object where“... fluctuation of the norm replaces the permanence of a law; where the object assumes a place in a continuum by variation” (Deleuze, 1991, p.38). This paper proposes to think objectile as the object of the architectural design, on three types of approximations between design and objectile: (a) Objectile as variable of the design, (b) Objectile as a design variable, and (c) Objectile as architecture (variable architecture). The second approximation (b) enables to discuss the conception of continuous design with power to cross other projects - a meta-design. The main aspect of this meta-design is the variability, another way of control based on concepts of patterns and modulations; however, objectile can mean the release of mind for new types of thought and new kinds of design based on “continuum by variation”: meta-design.

title	Toward Space Oriented BIM Practices
doi	https://doi.org/10.52842/conf.ecaade.2016.2.653
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 2, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 653-662
summary	When performing design tasks, architects think in terms of space, and act on physical elements. They often use various representation means to shape and to communicate the complex aspects of space. Architectural representation is often driven by visual perception whilst current BIM practices seem to be based on semantics associated with scheduling building items (element, position, quantity, etc.). The reduction of architectural sensitive approaches to merely technical ones, reveals only quantitative and restrictive information that does not reflect the architect's multi-sensorial experience. This paper examines some recent model proposals which include descriptions of architectural space concept, and tries to suggest a possible synthesis of this work. It focuses on cooperative practices necessary to unveil the sensitive dimension of the architectural design, and presents a state of existing BIM tools based on relevant tasks used in these practices in order to acquire more knowledge about the concepts which ensure a cooperative work taking into account the sensitive spatial aspects.
