A relatively new method to manufacture complex ceramic prototypes and components is additive manufacturing (AM). With the LCM (Lithography-based Ceramic Manufacturing)-technology the green body is manufactured layer-by-layer using selective curing of light-sensitive ceramic slurry by a mask exposure process. After curing by blue light the component is removed from the building platform and the green body is sintered to a ceramic component.The aim of this work is to investigate the influence of processing and layer architecture on the mechanical properties of an Yttria-stabilized zirconia ceramic. Strength tests were performed by uniaxial bending tests and by biaxial Ball-on-three Balls (B3B) tests. To identify typical fracture initiating flaws a systematic fractographic investigation was performed on different batches of Ball-on-three Balls-test and bending test specimens, respectively.Through additional investigations it was found that hardness and fracture toughness were independent on the layer architecture. But an extensive fractographic analysis showed that the strength was limited by flaws, which were introduced by processing and handling. If these flaws can be avoided by optimisation of the process the strength should be equal to that of conventional processed ceramics. © 2017 Elsevier Ltd.

The overall objective of the REProMag project is to develop and validate an innovative, resource-efficient manufacturing route (SDS process) for Rare Earth magnets that allows for the economically efficient production of net-shape magnetic parts with complex structures and geometries, while being 100% waste-free along the whole manufacturing chain. The new Shaping, Debinding and Sintering (SDS) process for Rare Earth magnets is an innovative automated manufacturing route to realise complex 3D- and multilayered parts; resulting in a significant increase in the material efficiency of at least 30% during manufacturing; while at the same time allowing additional geometrical features such as threads, cooling channels, small laminations/segments (e.g. to increase the efficiency of electrical motors) and structural optimisations such as lightweight-structures or the joint-free realisation. As part of the project, the possibility to produce hybrid parts such as an improved moving-coil transducer for headphones, loudspeakers and microphones will be evaluated. The SDS process allows a new level of sustainability in production, as the energy efficiency along the whole manufacturing chain can be increased by more than 30% when compared to conventional production routes. Moreover, the used raw material is 100% recycled and can be again recycled in the same way at the end of the lifetime of the products. In short, the innovative REProMag SDS process has the potential to manufacture complex structures of high quality and productivity with minimum use of material and energy, resulting in significant economic advantages compared to conventional manufacturing. The REProMag project is a highly innovative combination of applied research, technology development and integration, resulting in small-scale prototypes and a closely connected demonstration activity clearly showing the technical feasibility of the REProMag SDS processing route in a near to operational environment.

In this study, a new process for additive manufacturing (AM) of dense and strong ceramic objects is described. The lithography-based ceramic manufacturing (LCM) technique is based on the selective curing of a photosensitive slurry by a dynamic mask exposure process. The LCM technique is able to produce strong, dense and accurate alumina ceramics without virtually any geometrical limitations. With over 99.3% of a theoretical alumina density, four-point bending strength of 427 MPa, and very smooth surfaces, the LCM process distinguishes itself from other AM techniques for ceramics and provides parts with very similar mechanical properties as conventionally formed alumina. © 2014 The American Ceramic Society.

While Additive Manufacturing (AM)-technologies are already state-of-the-art in plastics processing or metalworking, the ceramic industry has been reluctant to implement this kind of technology due to insufficient quality of the parts produced by this means. Additive manufactured ceramics used to lack essential material properties such as density or strength, which hindered the application of such parts as technical ceramics. In this paper a new AM-technology, the Lithography-based Ceramic Manufacturing (LCM)-process, is presented. This technique is based on the selective curing of a photosensitive slurry by a mask exposure process. During the structuring, a photopolymer matrix is generated, which temporarily acts as scaffold and binder for the ceramic particles and is later on removed at elevated temperatures. Due to this approach, this novel technique achieves high green densities and thus, enables the production of strong, dense and accurate ceramic parts without any geometrical limitations. The parts produced using this technology have very similar mechanical properties as classical formed ceramic parts; for alumina a theoretical density of over 99.3 % and four-point bending strength of over 430 MPa has already been realized. These characteristics render the LCM-process an innovative and capable production method, especially in the case of complex shaped structures, customized parts or small series production.

In the field of ceramic processing, there is a strong need for the introduction of additive manufacturing (AM) technologies. Tools for ceramic injection molding (CIM) are expensive and require significant lead times which severely restrict the suitability of CIM for the production of small scale series or customized products. These are actually perfect conditions for the implementation of AM technologies; however, so far no adequate prototyping technology was available. The main reason for that are the high demands on high-performance ceramics - these materials are used where other materials fail, thus the quality and the reliability of the parts are crucial. In this paper a novel AMT-approach is presented, which is capable of producing strong, dense and accurate ceramic parts via a photopolymerization process, namely the Lithography-based Ceramic Manufacturing (LCM). For alumina a theoretical density of over 99, 4 % and 4-point bending strength of 430 MPa could already be realized. Moreover, due to its layer-by-layer approach, the LCM technology provides the opportunity to shape highly complex and intricate geometries that cannot be realized by conventional means. Holes with a diameter of 200 urn and a wall thickness of down to 150 μn could be realized by this technology to date. These characteristics render the LCM technology a capable addition to conventional processing techniques in the field of ceramics.
