“…A holistic definition of multi-material in the context of AM has been proposed by Girnth et al [15], which is concretized by Koopmann [16]. In this definition, MM is categorized depending on the geometrical dimensions in which the material is graded.…”

“…Work conducted by Kordaß et al, where metal powder filled pastes are extruded by nozzles, is the only exception [48,49]. Generally, 3D MM capabilities are achieved by combining two [15,16,50], three [33], or entire arrays [34,51] of nozzles depositing different materials. Alternatively, one or more nozzles can be combined with a holohedral powder coater to deposit the second or third material, respectively [18,52].…”

“…Sometimes, an additional suction nozzle is used to locally remove unsolidified excess material from the powder bed before a different material Fig. 4 Comparison of 3D-MM powder deposition concepts is applied [15,52]. Girnth et al summarized six different approaches to apply and-if necessary-remove two different powder materials using nozzle-based powder dispensers, a holohedral coater, and a suction unit [15].…”

In this review paper, the authors investigate the state of technology for hybrid- and multi-material (MM) manufacturing of metals utilizing additive manufacturing, in particular powder bed fusion processes. The study consists of three parts, covering the material combinations, the MM deposition devices, and the implications in the process chain. The material analysis is clustered into 2D- and 3D-MM approaches. Based on the reviewed literature, the most utilized material combination is steel-copper, followed by fusing dissimilar steels. Second, the MM deposition devices are categorized into holohedral, nozzle-based as well as masked deposition concepts, and compared in terms of powder deposition rate, resolution, and manufacturing readiness level (MRL). As a third aspect, the implications in the process chain are investigated. Therefore, the design of MM parts and the data preparation for the production process are analyzed. Moreover, aspects for the reuse of powder and finalization of MM parts are discussed. Considering the design of MM parts, there are theoretical approaches, but specific parameter studies or use cases are not present in the literature. Principles for powder separation are identified for exemplary material combinations, but results for further finalization steps of MM parts have not been found. In conclusion, 3D-MM manufacturing has a MRL of 4–5, which indicates that the technology can be produced in a laboratory environment. According to this maturity, several aspects for serial MM parts need to be developed, but the potential of the technology has been demonstrated. Thus, the next important step is to identify lead applications, which benefit from MM manufacturing and hence foster the industrialization of these processes.

A new course was designed to attract chemical and bioengineers to additive manufacturing and to provide them with an effective approach to this new field. The goal is a wider use of the advantages of additive manufacturing for complex multifunctional components in chemical process engineering. We describe the structure of the course and the experiences from the first two years. Students show great interest and are able to develop their own functional components with assistance. Yet many have deficits in the use of CAD software, which will be remedied in the future through a specific lecture.
