“…In recent years, the additive manufacturing (AM) of components made of polymers, metals, ceramics, or composites thereof have attracted many groups worldwide [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. In addition to the different variants of vat photopolymerization, like stereolithography (SLA), material extrusion methods (MEX), especially Fused Filament Fabrication, are widely used for component fabrication beyond commercial material usage.…”

“…For ceramics, a close cooperation between Fraunhofer IKTS and INMATEC Technologies recently presented the utilization of an alumina feedstock, originally designed for PIM, in FFF [ 14 , 15 ]. Beyond industry, several research groups are engaged in the realization of ceramic and metal components applying the huge bundle of different AM methods [ 1 , 4 , 16 , 17 , 18 ]. In case of MEX, the focus was mainly set on alumina, partially extending the application range to microsystems technology [ 19 , 20 , 21 , 22 , 23 , 24 , 25 ].…”

In this work, a process chain for the fabrication of dense zirconia parts will be presented covering the individual steps feedstock compounding, 3D printing via Fused Filament Fabrication (FFF) and thermal postprocessing including debinding and sintering. A special focus was set on the comprehensive rheological characterization of the feedstock systems applying high-pressure capillary and oscillation rheometry. The latter allowed the representation of the flow situation especially in the nozzle of the print head with the occurring low-shear stress. Oscillation rheometry enabled the clarification of the surfactant’s concentration, here stearic acid, or more general, the feedstocks composition influence on the resulting feedstock flow behavior. Finally, dense ceramic parts (best values around 99 % of theory) were realized with structural details smaller than 100 µm.

“…Although no longer a novelty, AM technology continues to revolutionize industries, in terms of technology as well as materials and processes used [42]. The European Association of Machine Tool Industries and Related Manufacturing Technologies [43] associates AM technology with the following four principles: In addition, lighter and more durable products are created with this technology, as compared to production using conventional technologies.…”

Smart Additive Manufacturing: The Path to the Digital Value Chain

The aim of this article is to characterize the impacts of Smart Additive Manufacturing (SAM) on industrial production, digital supply chains (DSCs) and corresponding digital value chains (DVCs), logistics and inventory management. The method used consists of a critical review of the literature, enriched by the authors’ field experience. The results show that digital transformation of manufacturing is affecting business models, from resource acquisition to the end user. Smart manufacturing is considered a successful improvement introduced by Industry 4.0. Additive Manufacturing (AM) plays a crucial role in this digital transformation, changing the way manufacturers think about the entire lifecycle of a product. SAM combines AM in a smart factory environment. SAM reduces the complexity of DSCs and contributes to a more flexible approach to logistics and inventory management. It has also spurred the growth and popularization of customized mass production as well as decentralized manufacturing, rapid prototyping, unprecedented flexibility in product design, production and delivery, and resource efficiency and sustainability. SAM technology impacts all five Fletcher’s stages in DVCs. However, the need for clear definitions and regulations on 3D printing of digital files and their reproduction, as well as product health, safety, and integrity issues, cannot be ignored. Furthermore, investment in this technology is still expensive and can be prohibitive for many companies, namely SMEs.

“…This steel is used as a matrix for many types of materials, as well as for hybrid composites [13]. Chromium-nickel stainless steels are applied via the layer deposition method to repair cracks on metal constructions [14]. Both structural and tool steels can be used for additive manufacturing if they are stable under the selected deposition method conditions [15].…”

In this study, we analyzed the quaternary Fe-C-Mn-B system to create new eutectic cast alloys for coating deposition and additive manufacturing. Experimental samples were fabricated via the wire arc manufacturing method with argon shielding using Kemppi Pro 5200 Evolution equipment. Annealing was performed in a vacuum electric furnace at 1273 K for 350 h. For phase analyses, Jeol Superprobe 733 equipment was used. Metallographic and differential thermal analyses were used to reveal the eutectic structure of the samples. Examinations of the quaternary Fe-C-Mn-B system demonstrated that several eutectic alloys existed in the system. Four isothermal pseudo-ternary sections of the Fe-C-Mn-B system were studied: “Fe3B”-Fe3C-“Fe3Mn”; Fe2B-“Fe2C”-“Fe2Mn”; “Fe3B”-Fe3C-“Fe1.2Mn”; “Fe23B6”-“Fe23C6”-“Fe23Mn”. Broad eutectic concentrations enabled us to overcome parameter fluctuations during additive manufacturing. In each isothermal section, two dissimilar phase regions were determined: one with a ternary Fe-C-B composition and the other with a ternary Fe-C-Mn composition. Depending on the manganese content, two types of solid solutions could be formed: (Fe, Mn)α or (Fe, Mn)γ.
