<p>Over the past decade robotic fabrication in architecture has succeeded where early digital architecture has fallen short: in the synthesis of the immaterial logic of computers and the material reality of architecture.  In light of this new/profound shift architectural theorist and historian of the ‘Digital Turn’ - Mario Carpo argues: ‘We no longer are witnessing the delayed modernization of an industry, but rather an historic departure: the modern division between intellectual work and manual production, between design and realization and manual production. Through this we see traditional modes of design becoming obsolete’.  The increasing power of digital design software, the widespread availability of digital fabrication tools, and the growing complexity of our built environment, are in stark contrast to the inefficient techniques that currently hinder today’s construction industry.  Furthermore, the utilisation of concepts from nature including biomemesis, biophilia, swarm tectonics, as well as cross-disciplinary influences - from the film industry to social sciences and artificial intelligence - has contributed significantly to the depth of change in the tools, and their subsequent delivery of, architecture.  Using nature and biological paradigms as a key influence for the work (specifically biological systems as defined by Menges, Wienstock and others) the thesis asks the question: How can biological theories on growth disrupt inert material perception within the discourse of 3D-printing architecture?  It seeks to consider a design and fabrication process that allows the dynamic potential found in natural systems (patterns, forms, behaviours, organisation) to design and build with far more complexity and sophistication. Such work could fore front notions of growth, evolution and natural forms of optimization compared to the current post industrialised notions of beauty. New computing capacity and assembly efficiencies should over time produce more advanced structures than are possible with current technologies.  The researcher is ‘aware’ of the range of fabrication methods available to the industry, firstly the invention of Computer Numerical Control (CNC) known primarily as a ‘subtractive method’ of machining and additive manufacturing machines (3D printers) by Charles Hull (1984) which revolutionized rapid prototyping throughout the automotive, aeronautic, and design industries.  The application of additive manufacturing workflows - in particular to the architectural field - holds significant potential to provide a fabrication method for the complex geometrical forms that substantiate the parametric design paradigm. However, contemporary attempts in mass fabrication of computer generated componentry are still costly in terms of practice, investment, and time... They are also complex in terms of assembly and co-ordination.  Using customized CAD/CAM workflow the author speculates a self-assembling ‘4-D’ architecture. As a piece of explorative design research, the thesis focuses primarily on the underlying philosophy and design methods, and looks to offer up a series of tectonic iterations that integrate form, surface and structure. These iterations have been designed and developed through complex surface pattern projection, a speculative technique developed by the author. It allows a use of direct additive 3d print to surface and enables a prototype fabrication system. This prototype system results in the production of self-assembling tension based membrane surface structures. These structures could, for example, be used for rapid deployment construction scenarios. (see final Design Research).  Resin-impregnation patterns are applied to 2-D pre-stretched form-active tension systems to induce 3-D curvature upon release. Form-finding is enabled through this method based on materials’ properties, organization and behavior. A digital tool is developed in the CAD environment that demonstrates the simulation of material behavior and its prediction under specific environmental conditions.  The methodology follows a systematic design-led research approach, in which physical form finding techniques, developed throughout the 19th and 20th centuries, are digitized via parametric 3D modelling software. Extensive physical modelling and analysis is conducted into a biomimetic approach to the design of fabric tensegrity surface structures, and their CNC fabrication potential explored. This research demonstrates the association between geometry and material behavior, specifically the elastic properties of resin impregnated Lycra membranes, by means of homogenizing protocols which translate physical properties into geometrical functions.  The work challenges the shifting role of the architect from that of an assembler of inert (discrete) material parts towards that of ‘an orchestrator of material effects’. This shift in role is enabled through the affordances of computational design tools, and emerging fabrication methods. Conclusions are drawn from the physical and digital explorations which redefine generative material-based design computation, supporting a synergetic approach to design integrating form, structure, material and environment.  How can biological theories on growth disrupt inert material perception within the discourse of 3D-printing architecture?</p>

Purpose The purpose of this paper is to present a novel methodology to produce a large boat hull with a foam additive manufacturing (FAM) process. To respond to shipping market needs, this new process is being developed. FAM technology is a conventional three-dimensional (3D) printing process whereby layers are deposited onto a high-pressure head mounted on a six-axis robotic arm. Traditionally, molds and masters are made with computer numerical control (CNC) machining or finished by hand. Handcrafting the molds is obviously time-consuming and labor-intensive, but even CNC machining can be challenging for parts with complex geometries and tight deadlines. Design/methodology/approach The proposed FAM technology focuses on the masters and molds, that are directly produced by 3D printing. This paper describes an additive manufacturing technology through which the operator can create a large part and its tools using the capacities of this new FAM technology. Findings The study shows a comparison carried out between the traditional manufacturing process and the additive manufacturing process, which is illustrated through an industrial case of application in the manufacturing industry. This work details the application of FAM technology to fabricate a 2.5 m boat hull mold and the results show the time and cost savings of FAM in the fabrication of large molds. Originality/value Finally, the advantages and drawbacks of the FAM technology are then discussed and novel features such as monitoring system and control to improve the accuracy of partly printed are highlighted.

Aiming at the problems of over stacking, warping deformation and rapid adjustment of layer thickness in electron beam additive manufacturing, the 3D printing slicing algorithm and partition scanning strategy for numerical control systems are studied. The GPU (graphics processing unit) is used to slice the 3D model, and the STL (stereolithography) file is calculated in parallel according to the normal vector and the vertex coordinates. The voxel information of the specified layer is dynamically obtained by adjusting the projection matrix to the slice height. The MS (marching squares) algorithm is used to extract the coordinate sequence of the binary image, and the ordered contour coordinates are output. In order to avoid shaking of the electron gun when the numerical control system is forming the microsegment straight line, and reduce metal overcrowding in the continuous curve C0, the NURBS (non-uniform rational b-splines) basis function is used to perform curve interpolation on the contour data. Aiming at the deformation problem of large block components in the forming process, a hexagonal partition and parallel line variable angle scanning technology is adopted, and an effective temperature and deformation control strategy is formed according to the European-distance planning scan order of each partition. The results show that the NURBS segmentation fits closer to the original polysurface cut line, and the error is reduced by 34.2% compared with the STL file slice data. As the number of triangular patches increases, the algorithm exhibits higher efficiency, STL files with 1,483,132 facets can be cut into 4488 layers in 89 s. The slicing algorithm involved in this research can be used as a general data processing algorithm for additive manufacturing technology to reduce the waiting time of the contour extraction process. Combined with the partition strategy, it can provide new ideas for the dynamic adjustment of layer thickness and deformation control in the forming process of large parts.

AbstractPhotopolymerization-based three-dimensional (3D) printing can enable customized manufacturing that is difficult to achieve through other traditional means. Nevertheless, it remains challenging to achieve efficient 3D printing due to the compromise between print speed and resolution. Herein, we report an efficient 3D printing approach based on the photooxidation of ketocoumarin that functions as the photosensitizer during photopolymerization, which can simultaneously deliver high print speed (5.1 cm h−1) and high print resolution (23 μm) on a common 3D printer. Mechanistically, the initiating radical and deethylated ketocoumarin are both generated upon visible light exposure, with the former giving rise to rapid photopolymerization and high print speed while the latter ensuring high print resolution by confining the light penetration. By comparison, the printed feature is hard to identify when the ketocoumarin encounters photoreduction due to the increased lateral photopolymerization. The proposed approach here provides a viable solution towards efficient additive manufacturing by controlling the photoreaction of photosensitizers during photopolymerization.

The use of additive manufacturing (AM) technologies is a relatively young research area in modern medicine. This technology offers a fast and effective way of producing implants, tissues, or entire organs individually adapted to the needs of a patient. Today, a large number of different 3D printing technologies with individual application areas are available. This review is intended to provide a general overview of these various printing technologies and their function for medical use. For this purpose, the design and functionality of the different applications are presented and their individual strengths and weaknesses are explained. Where possible, previous studies using the respective technologies in the field of tissue engineering are briefly summarized.
