Many digital fabrication machines have potential dangers, for example, sudden fires or projectile debris; thus, architects are generally required to supervise these machines when they employ them to make things. It is unlikely that further mechanization will ever completely eliminate such dangers since they result from unpredictable material processes. Therefore, as digital fabrication machines proliferate throughout architecture schools and practices, architects will find themselves spending increasingly more time supervising them, and waiting. In this paper, I argue that architects should then not only embrace waiting-with digital fabrication machines as a new form of architectural labor, but also begin to explore the ways in which such waiting can be productive. I begin with a critique of many architects’ impatience with digital fabrication processes. I then use the continental philosopher Henri Bergson’s concept of “intuition” to discuss the productive potential of waiting-with. Finally, I use a speculative 3D printing workflow to present additional creative possibilities that can arise if architects intentionally build waiting into digital fabrication processes.

Technology has the potential to transform the classroom, build access to new mathematical content, and provide access to students through unique representations. For this study, the authors considered the transformational promise of digital fabrication technology, specifically 3D printing, in a setting comprised of pre-service teachers. An introduction to digital fabrication session was implemented in a secondary mathematics methods course. Participants were assessed both prior to the experience and after, using an adapted TPACK developmental self-report survey to consider TPACK themes and subthemes. In this chapter, the authors describe ideas that emerged from narratives provided by participants, patterns of change noted from pre- to post-assessment, and three cases that emerged representing students who experienced the most positive changes, most negative changes, and least amount of change on self-perceived levels.

Teaching descriptive geometry, in the context of this study, is characterized by the continuous investment in recognizing digital representation technologies which can enhance the didactic activities in architectural training. This study describes this trajectory which includes the use of virtual reality, augmented reality and parametric modelling, as well as freehand drawing and the production of physical models both by automating the unfolding process and by digital fabrication processes of 3D printing and laser cutting. In addition to questioning the relevance and sustainability of the infrastructure needed to ensure the continuation of this trajectory, the potentialities identified in each of the learning activities that have been structure, are shown. Although these potentialities are specific to this context, it is considered that this type of record contributes to understand the issues being faced in teaching practices.

Concrete shells are a very effective type of building structures due to their ability to bridge large spans with minimal construction thickness. This type of building structures built on the medieval vaulting techniques and, regarding the use of reinforced concrete over the last 100 years, it has overcome the limitations of the masonry vaulting technologies and enabled to increase the span of structures to tens of meters. The construction technology to realize concrete shells using monolithic casting into formwork is besides abovementioned advantages characterized by high labour and thanks to the cost and manufacturing intensity of double curved formwork panels it allows economical realization of only selected structural geometries. Its considerable limitation is, besides the costly production of double curvature formwork, also the laborious installation of formwork and falsework structures. The solution seems to be in line with the upcoming transition to Construction 4.0 robotizing the construction technology of shells that could create a similar increase in productivity and design possibilities as was the technological transition between vaults and shells. One of the promising technologies of robotic production seems to be digital fabrication methods and, in particular, 3D printing or in other words additive manufacturing. This wasteless technology, which has been used to date for experimental projects mainly for the realization of vertical bearing structures, has, despite the first attempts at realizing vaults, a number of technological limitations. In this article, authors aim to summarize and indicate possible constraints of on site 3D printing of domes. They further indicate the possible ways to overcome these limitations and suggest two different means of on site 3D printing of hemispherical dome and the dome based on the catenary profile using extrusion nozzles with different profiles. Finally they discuss the Eurocode requirements for concrete shells and suggest technological solutions for on site 3D printed shells in terms of structural reinforcement.

Purpose The purpose of this paper is to describe a novel design workflow for the digital fabrication of custom-made orthoses (CMIO). It is intended to provide an easier process for clinical practitioners and orthotic technicians alike. It further functions to reduce the dependency of the operators’ abilities and skills. Design/methodology/approach The technical assessment covers low-cost three-dimensional (3D) scanning, free computer-aided design (CAD) software, and desktop 3D printing and acetone vapour finishing. To analyse its viability, a cost comparison was carried out between the proposed workflow and the traditional CMIO manufacture method. Findings The results show that the proposed workflow is a technically feasible and cost-effective solution to improve upon the traditional process of design and manufacture of custom-made static trapeziometacarpal (TMC) orthoses. Further studies are needed for ensuring a clinically feasible approach and for estimating the efficacy of the method for the recovery process in patients. Social implications The feasibility of the process increases the impact of the study, as the great accessibility to this type of 3D printers makes the digital fabrication method easier to be adopted by operators. Originality/value Although some research has been conducted on digital fabrication of CMIO, few studies have investigated the use of desktop 3D printing in any systematic way. This study provides a first step in the exploration of a new design workflow using low-cost digital fabrication tools combined with non-manual finishing.

Extrusion-based three-dimensional (3D) printing methods are preferred and emerging approaches for freely digital fabrication of ceramics due to ease of use, low investment, high utilization of materials, and good adaptability to multi-materials. However, systematic knowledge still lacks an explanation for what is their 3D printability. Moreover, some uncontrollable factors including extrudate shape retention and nonuniform drying inevitably limit their industrial applications. The purpose of this research was to present a new shaping retention method based on mathematical synthesis modeling for extrusion-based 3D-printing of ceramic pastes. Firstly, the steady-state equilibrium equation of the extrusion process was derived to provide clearer theoretical indications than purely experimental methods. Furthermore, a mathematical description framework was synthesized to better understand the extrusion-based 3D-printing of ceramic pastes from several realms: pastes rheology, extrudability, shape-holdability, and drying kinetics. Secondly, for eliminating shaping drawbacks (e.g., deformation and cracks) originating from non-digital control factors, we put forward a digital shape-retention technology inspired by the generalized drying kinetics of porous materials, which was different from existing retention solutions, e.g., freezing retention, thermally induced gelation, and using removable support structures. In addition, we developed an in situ hot air flow drying device easily attached to the nozzle of existing 3D printers. Confirmatory 3D-printing experiments of thin-walled cone-shape benchmark parts and the fire arrowhead-like object clearly demonstrated that the presented shape-retention method not only upgraded layer-by-layer forming capability but also enabled digital control of extrudate solidification. In addition, many more experimental results statistically showed that both fully solid parts and purely thin-wall parts had higher dimensional accuracy and better surface quality than the offline drying method. The 3D printed ceramic products with complex profiled surfaces conceivably demonstrated that our improved extrusion-based 3D-printing process of ceramic pastes has game-changing potentials beyond the traditional craftsmanship capacity.

Digital fabrication, and especially 3D printing, is an emerging field that is opening up new possibilities for craft, art and design. The process, however, has important limitations; in particular, digitally designed artifacts are intrinsically reproducible. In stark contrast, traditional craft artifacts are individually produced by hand. The authors combine digital fabrication and craft in their work involving object destruction and restoration: an intentionally broken crafted artifact and a 3D printed restoration. The motivation is not to restore the original work but to transform it into a new object in which both the destructive event and the restoration are visible and the re-assembled object functions as a memorial.

AbstractThe paper presents an ongoing project focusing on the application of additive manufacturing technologies for the design of staircases. Additive digital fabrication allows architects to reinvestigate materials, processes, and creates new design opportunities to explore novel aesthetical and functional expression in architecture, enabling a reinterpretation of the typology of the staircase, using thermoplastic materials. This paper reviews the opportunities and challenges of using 3D printing for fabricating custom stairs with complex geometries in two studied configurations.
