“…3D-printed fuel nozzles have enabled General Electric's LEAP engine to reduce the number of sub-parts from eighteen to only one. This improved the durability of components and reduced its weight by 25%, but also enabled a better optimized geometry to achieve higher combustion efficiency, leading to fuel savings throughout the life of the engine and reducing its CO 2 emissions [20]. 3D-printing and other Additive Manufacturing technologies can be very resource efficient for specific manufacturing applications, such as prototypes, products with small lots and high variances or when making long transportation obsolete (e.g., when printing spare parts for airplanes instead of flying them in).…”

Industrial production plays an important role for achieving a green economy and the sustainable development goals. Therefore, the nascent transformation of industrial production due to digitalization into a so-called Industrial Internet of Things (IIoT) is of great interest from a sustainable development point of view. This paper discusses how the environmental dimension of a sustainable development can potentially benefit from the IIoT-focusing especially on three topics: resource efficiency, sustainable energy and transparency. It presents a state of the art literature analysis of IIoT-enabled approaches addressing the three environmental topics. This analysis is compared with the findings of a survey among Chinese industrial companies, investigating the sustainability-related expectations of participants coming along with the implementation of IIoT solutions. China has been chosen as a case study because it brings together a strong industrial sector, ambitious plans regarding industrial digitalization and a high relevance and need for more sustainability. The survey was conducted with the means of a questionnaire which was distributed via email and used for direct on-site interviews. It focused on large and medium sized companies mainly from Liaoning Province and had a sample size of 109 participants.

“…Arguably, energy consumption may pose an issue from a sustainability point of view, which is estimated to be 100-fold higher in 3DP processes than in traditional manufacturing processes [5]. This assertion is subject to debate as some other studies proposed the opposite (e.g., [6][7]). There are lots of research studies that have investigated 3DP technology, especially in the material engineering domain.…”

The 3D Printing (3DP) industry has been receiving increased public attention. Many companies are seeking ways to develop new means of creating and disseminating 3DP content, in order to capture new business opportunities. To date, however, the true business opportunities of 3DP have not been completely uncovered. This research explores the challenges posed in the development and deployment of 3DP, and focuses on China which is still the main manufacturing hub in the world. By means of empirical semi-structured interviews with 3DP companies in China, the current application of 3DP technology in the industry and the associated challenges are investigated. Although many companies can see the benefits of 3DP, its potential has not been delivered as promised. Several areas have been identified that could be improved further. The interviews with 3DP companies are used to learn about the gap between the 3DP technology in depth, and 3DP industrial applications which can further improve the growth of the 3DP industry.

“…The realization of structures of this type, with a controlled porosity, reduced dimensions of the details, and articulated geometry, is very difficult to achieve with traditional foundry and molding techniques. These needs may instead be exhaustively fulfilled by additive manufacturing technologies, in particular selective laser melting (SLM), a laser powder bed fusion (LPBF) process that allows the manufacturing of metal components through selective melting of powders, layer by layer [17,18]. Fusion occurs only in the areas necessary for the realization of the component according to the information obtained by the stereo lithography (STL) digital format of the 3D model.…”

A Robust Multifunctional Sandwich Panel Design with Trabecular Structures by the Use of Additive Manufacturing Technology for a New De-Icing System

et al. 2017

Anti-ice systems assure a vital on-board function in most aircraft: ice prevention or de-icing is mandatory for all aerodynamic surfaces to preserve their performance, and for all the movable surfaces to allow the proper control of the plane. In this work, a novel multi-functional panel concept which integrates anti-icing directly inside the primary structure is presented. In fact, constructing the core of the sandwich with trabecular non-stochastic cells allows the presence of a heat exchanger directly inside the structure with a savings in weight and an improvement in thermal efficiency. This solution can be realized easily in a single-piece component using Additive Manufacturing (AM) technology without the need for joints, gluing, or welding. The objective of this study is to preliminarily investigate the mechanical properties of the core constructed with Selective Laser Melting (SLM); through the Design of Experiment (DOE), different design parameters were varied to understand how they affect the compression behaviour.
