“…Multi Jet Fusion (MJF) is a relatively new and promising technology developed by Hewlett-Packard (HP) and introduced in 2017 [12]. Just like SLS, it uses powdered materials; however, instead of sintering the particles by means of a laser heat source, an inkjet printhead forms 3D components by applying two different binder fluids (fusing and detailing agents) to the surface of the powder bed.…”

This paper describes a surface-roughness study performed on samples manufactured additively using the Multi Jet Fusion (MJF) technology. The samples were divided into three groups based on the material used in the process: polypropylene (PP), thermoplastic polyurethane (TPU), and polyamide 11 (PA11). Subsequently, they were tested by means of a roughness-measuring system, which made it possible to determine the typical surface roughness parameters (Ra, Rq, Rz). The tests were designed to examine whether the placement and orientation of 3D objects while printing, in connection with the material used, can significantly influence the surface quality of MJF-printed objects. The results show that the TPU samples have a surface roughness much higher than the PP and PA11 ones, which exhibit roughness levels very similar to each other. It can also be concluded that surfaces printed vertically (along the Z-axis) tend to be less smooth—similarly to the surfaces of objects made of TPU located in the central zones of the print chamber during printing. This information may be of value in cases where low surface roughness is preferred (e.g., manufacturing patient-specific orthoses), although this particular study does not focus on one specific application.

Additive manufacturing (AM or 3D printing) is known for large capacities like design freedom, reduced tooling, and production hours. AM evolving exciting advancements for new business models in different industries. Few research papers and studies are limited to material specifications, processes, or quality issues. So, this literature review combined with considerations of AM for polymers materials to quality process to get basic ideas or to lay the groundwork for future researchers. To outline the critical points for investigative queries and identify research gaps in this literature with primarily detailed info on innovation technologies. This review states polymers materials optimization and its manufacturing, all-purpose design considerations, and limitations define CAD source printing and step-by-step quality processes for the fortitude of the analysis to create previous research intended to advantage researchers for future business practices in Industrial revolution 4.0.

“…While Industry 4.0 solutions are directly subject to the challenges of sustainable and efficient material and resource use, the fundamental environmentally sustainable nature of CPPSs as potential drivers of the Fourth Industrial Revolution have already been demonstrated [1,8,[18][19][20]. Real production scenarios have also been used to show how simulations, measurement tools, and campaigns can help to improve the energy and resource flows [21]. Nevertheless, the current research in this area raises the question of the extent to which digital solutions can help to achieve the environmental goals [15].…”

Manufacturing companies increasingly have to address the risks and contributions related to their environmental impacts. Therefore, more data are needed in order to provide full transparency with regard to production, and to highlight the potential relationships between the process data and the environmental impacts. In order to achieve this data transparency, targeted digitalization is needed that is tailored to the goal of reaching minimized environmental impacts. Cyber-physical production systems (CPPSs) are central for the digitalization of manufacturing. However, they may also come with an initial environmental backpack. Due to unawareness of relevant interdependencies when setting up CPPS, data may be collected which is not helpful or necessary for the development of sustainability-oriented CPPS. Therefore, a critical assessment is required which data is necessary to support sustainable manufacturing and to avoid unreflective data collection. This requires the identification of the relevant factors and their interdependencies within the context of sustainability in production. By identifying the influencing factors, the measurement strategy can be linked to the appropriate sensor technologies that explicitly contribute to the target fulfillment. The design of more sustainable data structures using a cross-impact analysis is illustrated in this paper as a generic methodological approach, which will be applied to a 3D-printing use case.
