Due to its specific properties, additive manufacturing has great potential in terms of several aspects. To use this potential, appropriate additive manufacturing processes are needed. For the production of end products made of polymers, the additive manufacturing process category of powder bed fusion has a great potential. The High Speed Sintering (HSS)- or Multi Jet Fusion (MJF)-process currently shows the greatest potential in terms of cost, time and quality. Due to the fact that this potential was recognized not long ago, there is still significant research and development needed. Implementation and application possibilities of the process must be explored in order to enable an effective use of these potentials. Furthermore, there is a need for research and development in terms of the production plant, to enable its use in an industrial environment. There is also still a great need to explore and develop the process itself respectively the layer-on-layer build process. The aim of the chair Manufacturing and Remanufacturing Technology is to research and develop knowledge and solutions for this by means of defined research projects. A processing of these research projects is only possible by means of a manufacturing plant, which uses the HSS- respectively MJF-process. Currently, however, there is no production plant of this category available at the University of Bayreuth.

由于其特定的特性，增材制造在几个方面具有巨大的潜力。为了利用这种潜力，需要适当的增材制造工艺。对于由聚合物制成的最终产品的生产，粉末床熔融的增材制造工艺类别具有很大的潜力。高速烧结（HSS）或多射流熔融（MJF）工艺目前在成本、时间和质量方面表现出最大的潜力。由于这种潜力不久前才被认识到，因此仍需要进行大量的研究和开发。必须探讨这一进程的执行和应用可能性，以便能够有效利用这些潜力。此外，还需要对生产设备进行研究和开发，以使其能够在工业环境中使用。仍然有很大的需要去探索和开发过程本身，分别是层对层的构建过程。椅子制造和再制造技术的目的是通过定义的研究项目来研究和开发知识和解决方案。这些研究项目的处理只能通过制造工厂进行，该工厂使用HSS-相应的MJF工艺。然而，目前在拜罗伊特大学还没有这类生产工厂。
