Abstract:

Augmented/Virtual Reality (AR/VR) is still a fragmented space to design for due to the rapidly evolving hardware, the interdisciplinarity of teams, and a lack of standards and best practices. We interviewed 26 professional AR/VR designers and developers to shed light on their tasks, approaches, tools, and challenges. Based on their work and the artifacts they generated, we found that AR/VR application creators fulfill four roles: concept developers, interaction designers, content authors, and technical developers. One person often incorporates multiple roles and faces a variety of challenges during the design process from the initial contextual analysis to the deployment. From analysis of their tool sets, methods, and artifacts, we describe critical key challenges. Finally, we discuss the importance of prototyping for the communication in AR/VR development teams and highlight design implications for future tools to create a more usable AR/VR tool chain.

Abstract:

The Additive Manufacturing (AM) industry is investing more and more in 3D Printing, which has opened new paths and opportunities in the field of Smart Manufacturing, providing previously unfathomable technological innovations in every sector. This paper presents a robust methodology approach to empower users through low-cost and Do-It-Yourself activities for rapid prototyping of Smart Luminous Artifacts using different AM technologies as follows: a) Stereolithography (SLA) was used for the fabrication of the 3D printed transparent artifact which is printed using optical transparent resin, b) multi-functional ink-jet circuit printing using silver nanoparticle inks on plastic substrates for producing hybrid Printed Circuit Boards (PCB) with unique geometry and interconnect architecture with various levels of component embedding, and c) Fused Filament Fabrication (FFF) technology for printing the electronics housing. In the case of the printed PCB electrodes, a process optimization study was performed at annealing temperatures of 180, 200, 220 ℃ for 30 min. The macro- and micro-morphology of the PCB printed electrodes were investigated by Stereo-Microscopy and Scanning Electron Microscopy (SEM) respectively, while the printed electrode thickness was calculated by exploiting auto-focus track tool of inVia Raman Spectroscopy. The customised 3D printed parts were assembled under simplicity and low power consumption, to create the 3D printed Smart Luminous Artifacts, which are combined with advanced IoT functionalities in order to be controllable via Wi-Fi and Bluetooth by a user-friendly mobile application. This methodology approach is ideal for being followed by educators in high schools, colleges and universities to train the students and engineers on co-creation and co-design using digital manufacturing technologies.

Abstract:

The current study investigates the performance of Additive Manufactured (AM) silica (SiO2) scaffolds using advanced lattice designs. In particular, six specific lattice design structures based on Strut-Lattice Structures and on Triply Periodic Minimal Structures (TPMS) were additively manufactured by utilising the Stereolithography method. Initially, the mechanical and morphological behaviour of solid 3D printed specimens was studied using characterization techniques, such as instrumented nanoindentation and Scanning Electron Microscopy (SEM) in order to understand the material behaviour. Then, the AM complex lattice structures were tested under a quasi-static uniaxial compression loading in order to reveal their mechanical response, which is depended on their relative density and also to deduce the stress strain response. The results have shown that all structures presented extensive degradation in mechanical behaviour due to the influence of scaling laws and the existing porosity in the structure originated from the manufacturing procedure. However, strut-structures exhibited more severe deterioration in their mechanical properties compared with TPMS structures. This mechanical study of AM ceramic lattice structures is an essential step prior to further exploration and research of the ceramic 3D printed lattice scaffolds in tissue engineering.

Abstract:

Over the last couple of years, human oriented manufacturing, also called social manufacturing, became an ever more important aim in the transition into an industry 4.0. One of the best ways of doing that is to bring the end users, manufactures, and other participants from the production and design process closer together, so they can all make improved and socially sustainable products a reality. Prototyping, as a part of the design thinking process, plays a significant role in the physical and virtual implementation of a concept and is an essential phase during the collaborative design and search for new ideas. Depending on the project objectives and the collaborator skills and preferences, different forms of prototyping can be applied. This paper describes a prototyping platform that makes use of the combination of different prototyping techniques. The proposed approach for collaborative prototyping is illustrated with an example of the idea development for several interaction scenarios of different complexity.

Abstract:

iPRODUCE is a European-funded project that embraces and explores the connections between several concepts, namely open innovation, social manufacturing, co-creation, and collaboration. iPRODUCE is a 42-month project, which started in January 2020, whose full title is “A Social Manufacturing Framework for Streamlined Multi- stakeholder Open Innovation Missions in Consumer Goods Sectors”. Simplifying, and considering the mentioned concepts, the iPRODUCE project has worked towards the development of a social manufacturing platform that enables the interaction and collaboration between different types of actors and stakeholders, particularly focusing on user-driven open-innovation and co-creation. Moreover, it explores these collaboration activities in several consumer sectors, including furniture, electronics, mobility, and others.

Abstract:

This article presents a case that joins user-driven innovation and additive manufacturing (AM) towards latent business opportunities in the preparation for life threatening operations. Surgeons, confronted with a patient with a delicate heart condition, collaborated with a prototyping facility to print a realistic 3D model of the patient’s aortic aneurysm. The model allowed the surgeons to first study and then experiment to determine the most effective operation procedure before the actual operation, which shortened the surgery time by approximately 70%. Reducing surgery time creates two forms of value: improving patient outcomes and reducing costs. Shorter times under anesthetic and on cardiopulmonary bypass correlate with better surgical results. Reducing healthcare costs brings broad societal benefits in both publicly and privately funded healthcare systems. We outline a case for makerspaces to capture value by joining their expertise and manufacturing equipment with the needs of nearby healthcare systems for novel business developments.
