“…Manufacturing one-off end-user products with traditional processes, many of which were refined for mass-production, can be very expensive and wasteful of energy and resources. The emergence of "additive manufacturing" (AM) technologies has promised to mitigate this to a large degree, as waste can be minimized, energy consumption is relatively low, and the production of specialized tooling is mostly eliminated [1][2][3][4]. Questions remain about the maturity of the technology, but it is becoming increasingly feasible to use AM as an end-user manufacturing process for in some industries.…”

This paper describes the collection of a large dataset (6930 measurements) on dimensional error in the fused deposition modeling (FDM) additive manufacturing process for full-density parts. Three different print orientations were studied, as well as seven raster angles ( 0 ∘ , 15 ∘ , 30 ∘ , 45 ∘ , 60 ∘ , 75 ∘ , and 90 ∘ ) for the rectilinear infill pattern. All measurements were replicated ten times on ten different samples to ensure a comprehensive dataset. Eleven polymer materials were considered: acrylonitrile butadiene styrene (ABS), polylactic acid (PLA), high-temperature PLA, wood-composite PLA, carbon-fiber-composite PLA, copper-composite PLA, aluminum-composite PLA, high-impact polystyrene (HIPS), polyethylene terephthalate glycol-enhanced (PETG), polycarbonate, and synthetic polyamide (nylon). The samples were ASTM-standard impact-testing samples, since this geometry allows the measurement of error on three different scales; the nominal dimensions were 3 . 25 mm thick, 63 . 5 mm long, and 12 . 7 mm wide. This dataset is intended to give engineers and product designers a basis for judging the accuracy and repeatability of the FDM process for use in manufacturing of end-user products.

“…Lou et al [46] were amongst the first few people to investigate the overall environmental performance of SLA by developing an environmental performance assessment model considering material consumption, energy consumption and end-of-life scenarios. Similarly, many authors also worked on environmental impact assessment of different AM technologies [39,40,46,47,49,60]. The papers analysed in the environmental impact assessment are presented in Table 2.…”

Additive manufacturing (AM) is a group of technologies that create objects by adding material layer upon layer, in precise geometric shapes. They are amongst the most disruptive technologies nowadays, potentially changing value chains from the design process to the end-of-life, providing significant advantages over traditional manufacturing processes in terms of flexibility in design and production and waste minimization. Nevertheless, sustainability assessment should also be included in the research agenda as these technologies affect the People, the Planet and the Profit: the three-bottom line (3BL) assessment framework. Moreover, AM sustainability depends on each product and context that strengthens the need for its assessment through the 3BL framework. This paper explores the literature on AM sustainability, and the results are mapped in a framework aiming to support comprehensive assessments of the AM impacts in the 3BL dimensions by companies and researchers. To sustain the coherence of boundaries, three life cycle methods are proposed, each one for a specific dimension of the 3BL analysis, and two illustrative case studies are shown to exemplify the model.

“…Distribution of food industry papers between industry dynamics/future and gastronomy To examine social, environmental and economic dimension of 3DFP, the review of the literature has been performed on the direction of having a deep look to the studies for these three main dimensions as well as sustainability and technological perspective. While there are some studies and reports about these aspects, the vast majority of the papers has been related to 3D Printing in general, industrial applications; metals, plastics, new materials at most as some of them are also referenced [21], [22], [23], [24], [25] by obtaining the information for being adapted to the extent of food printing.

3D Printing or Additive Manufacturing (AM) has become an emerging trend in global production area with a wide range of application fields. The increasing number of the concepts indicates the opportunity to address the needs and challenges of AM in both food industry and global scale. The technological, resource and industrial aspects of 3D Food Printing have the potentialities to enable to 'print' highly customized food, not just about the shape, but also about the structure, texture, flavor, taste, nutritional value, new edible alternatives and specific formulations for different choices, where the individual meals become possible. Anyway, the increasing importance of global concerns push towards the consideration if the value of the printed meal and 3D Printing itself can be sustainable and how. Whereas several studies claim to address the sustainability of 3Dfood printing, it is not clear yet what is the state of the art of 3D Food Printing within the sustainability intersection of economic, environmental and social pillars. Starting from the presentation of the available current approaches and practices, the paper provides a holistic outlook of the topic, shows the parameters that impact the sustainability of the technology and propose the improvements to be applied for completing the sustainability view and to achieve the 3D food printing full potential.
