“…The figure indicates that with higher impact AM scenarios, the energy usage reduction is an order of magnitude greater than lower AM impact scenarios. These were provided by Verhoef et al [14] and they observed, Scramble with high (SH) AM impact showed manufacturing closer to point of use, less long-distance freight transport, but limited new product design by AM. Blueprints with high (BH) AM impact showed manufacturing near the point of use with business justification, supply chain disintermediation with less intermediaries, reduction in the time to market, and mass customization.…”

Additive manufacturing is the buzz word these days and many companies are leaning on this technology to leap forward in un-chartered design space that promises to give better performance at impossible to reach design goals with the current manufacturing methods. This paper addresses recent developments that have occurred in Energy related businesses with the adoption of 3D printing, also known as Additive Manufacturing (AM). It covers what and why of additive manufacturing; what constitutes energy and AM industry; current activities in AM for energy; AM for different energy sectors; AM processes; AM applications; selected patents in additive manufacturing associated with energy applications; and economic and financial aspects of AM in energy related industries. In this review paper it was noted that in-spite of phenomenal growth in AM, it seldom replaces traditional production methods due to associated constraints. Many companies are finding complimentary AM processes along with subtractive manufacturing techniques to meet the market demands. However, AM is particularly advantageous and attractive compared to traditional manufacturing methods for low volume complex geometry parts.

“…Unleashed from the constraints of traditional manufacturing (eg, tooling, casting, and postproduction heat treatments), it enables mass customization with increased production speed and quality, bringing significant savings to the fabrication costs and material waste. It is estimated that 3‐D metal printing has the potential to save global CO 2 emissions of between 4% to 21% by 2050 . High‐tech industries such as automotive and aerospace have already embraced this technology.…”

Steel tubular profiles have outstanding mechanical and architectural performances, but their joints must be manufactured with a vast number of welds and local stiffeners, resulting in complex fabrication and low structural reliability under extreme loads. Fatigue failure is usually a dominant parameter in their design. On the other hand, nature perfectly optimizes its structures with minimized stress concentrations resulting in an extensive fatigue life. In the case of tubular structures, the nodes between the bamboo body and branches are inspiring examples. This article discusses how smarter solutions can be achieved using inspiration from nature by setting the objective of topology optimization to enhance the structural integrity of welded tubular joints between 3‐D‐printed and conventional steel components. Rather than focusing on the “weight reduction,” it prioritizes the objectives of resistance, robustness, and durability. 3‐D metal printing technology, unleashed from the constraints of traditional manufacturing, can enable this structural customization, bringing substantial savings to tubular joint fabrication costs and material waste. To quantify the performance of such joints, the strain energy density method can be the right tool, thanks to its independence on mesh size. This paper provides a review of these subjects and presents brief results of a case study.

“…It was estimated that by 2050, AM could save up to 90% of the raw material needed for manufacturing [3].Nonetheless, the possibilities of AM are not only limited to a reduction of raw material usage. The possibility of manufacturing lighter components could lead to energy savings, estimated between 5% and 25% by 2050, as well as a reduction in manufacturing costs of around 4-21% for the same period [7]. This trend is applicable to different industrial sectors.…”

Additive Manufacturing, AM, is considered to be environmentally friendly when compared to conventional manufacturing processes. Most researchers focus on resource consumption when performing the corresponding Life Cycle Analysis, LCA, of AM. To that end, the sustainability of AM is compared to processes like milling. Nevertheless, factors such as resource use, pollution, and the effects of AM on human health and society should be also taken into account before determining its environmental impact. In addition, in powder-based AM, handling the powder becomes an issue to be addressed, considering both the operator´s health and the subsequent management of the powder used. In view of these requirements, the fundamentals of the different powder-based AM processes were studied and special attention paid to the health risks derived from the high concentrations of certain chemical compounds existing in the typically employed materials. A review of previous work related to the environmental impact of AM is presented, highlighting the gaps found and the areas where deeper research is required. Finally, the implications of the reuse of metallic powder and the procedures to be followed for the disposal of waste are studied.2 of 25 sold in 2016 was 983, whereas, in the year 2017 this value rose to 1768 units, which implies an 80% increase [1].As far as economy and sustainability are concerned, AM offers several advantages over conventional manufacturing techniques, which confers many potential applications to AM in diverse industrial sectors, such as automotive, aerospace, biomedical, energy, and consumer goods [4]. In the aerospace industry, for example, AM enables aerospace motorists to create blades with much more complex internal cooling channels, allowing engines to run at higher temperatures and thus increase their performance [5]. In the report presented by the National Institute of Standards and Technology (NIST) of the U.S. Department of Commerce, it is stated that in aerospace engines titanium parts are machined down to size from large initial blocks, which leads to more than 90% waste material, material waste that could be reduced by using AM [6]. The European Commission in the Digital Transformation Monitor of 2017 presented similar numbers, where the disruptive nature of 3D printing was studied. It was estimated that by 2050, AM could save up to 90% of the raw material needed for manufacturing [3].Nonetheless, the possibilities of AM are not only limited to a reduction of raw material usage. The possibility of manufacturing lighter components could lead to energy savings, estimated between 5% and 25% by 2050, as well as a reduction in manufacturing costs of around 4-21% for the same period [7]. This trend is applicable to different industrial sectors. For example, SmarTech expects the overall market for AM in automotive to reach 5.3 billion USD in revenues by 2023 and to achieve 12.4 billion USD by 2028 [8].The lack of European and international standardization related to AM is proving to be an impediment to the...
