The AUT Creative Industries Research Institute (CIRI) is a hub which weaves together the many creative strands running through the Faculty of Design and Creative Technologies.

The Pacific Media Centre, one of five foundation research centres of CIRI, produced an extensive archive (2007-2020) of news and current affairs, articles, videos, book chapters and books by the PMC team and its group of associated international researchers. Its directory of peer-reviewed communication and media research abstracts is here: https://pmcarchive.aut.ac.nz/research.html, and the research journal Pacific Journalism Review is at Tuwhera: https://ojs.aut.ac.nz/pacific-journalism-review/

    Curved layer fused deposition modeling
    (Sabinet, 2010) Singamneni, S; Diegel, O; Huang, B; Gibson, I; Chowdhury, R
    Current Fused Deposition Modeling (FDM) technologies deposit material as flat layers. The result is a “stair-case” effect on non-vertical or horizontal surfaces, and compromised part strength because of weakness between the laminations. This paper describes a FDM method through which layers of build material are deposited as curved layers following the shape of the part, thus removing the stair-case effect and creating parts that have an even strength distribution over their entire surface. Support material is first deposited as conventional flat layers, and build material is then deposited over the support structure following the curves of the part. The paper discusses a proof of concept of the system, the algorithms used to generate the curve paths for the deposition head, and examines the challenges and possibilities of this technology, including the capability of including composite materials.

    Curved layer fused deposition modeling in conductive polymer additive manufacturing
    (Trans Tech Publications, 2011) Diegel, O; Singamneni, S; Huang, B; Gibson, I
    This paper describes a curved-layer additive manufacturing technology that has the potential to print plastic components with integral conductive polymer electronic circuits. Researchers at AUT University in New Zealand and the National University of Singapore have developed a novel Fused Deposition Modeling (FDM) process in which the layers of material that make up the part are deposited as curved layers instead of the conventional flat layers. This technology opens up possibilities of building curved plastic parts that have conductive electronic tracks and components printed as an integral part of the plastic component, thereby eliminating printed circuit boards and wiring. It is not possible to do this with existing flat-layer additive manufacturing technologies as the continuity of a circuit could be interrupted between the layers. With curved-layer fused deposition modeling (CLFDM) this problem is removed as continuous filaments in 3 dimensions can be produced, allowing for continuous conductive circuits.

    Getting rid of the wires: Curved Layer Fused Deposition Modeling in Conductive Polymer Additive Manufacturing
    (Trans Tech Publications, 2011) Diegel, O; Singamneni, S; Huang, B; Gibson, I
    This paper describes an additive manufacturing technology that has the potential to print plastic components with integral conductive polymer electronic circuits. This could have a major impact in the fields of robotics and mechatronics as it has the potential to allow large wiring looms, often an issue with complex robotic systems, to be printed as an integral part of the products plastic shell. This paper describes the development of a novel Fused Deposition Modeling (FDM) process in which the layers of material that make up the part are deposited as curved layers instead of the conventional flat layers. This opens up possibilities of building curved plastic parts that have conductive electronic tracks and components printed as an integral part of the plastic component, thereby eliminating printed circuit boards and wiring.

    Tools for sustainable product design: additive manufacturing
    (Canadian Center of Science and Education, 2010) Diegel, O; Singamneni, S; Reay, S; Withell, A
    The advent of additive manufacturing technologies presents a number of opportunities that have the potential to greatly benefit designers, and contribute to the sustainability of products. Additive manufacturing technologies have removed many of the manufacturing restrictions that may previously have compromised a designer’s ability to make the product they imagined. Products can also be extensively customized to the user thus, once again, potentially increasing their desirability, pleasure and attachment and therefore their longevity. As additive manufacturing technologies evolve, and more new materials become available, and multiple material technologies are further developed, the field of product design has the potential to greatly change. This paper examines how aspects of additive manufacturing, from a sustainable design perspective, could become a useful tool in the arsenal to bring about the sustainable design of consumer products.
