The MultimaterialAdditiveManufacturing research area generates cross-faculty research ideas, identifies synergies and enables the use of research equipment for interested scientists at HTWK Leipzig and external parties.
The Multimaterial AM research area also links the cross-faculty Leipzig Centre of Materials Science with the Institute for Printing, Packaging and Processing (iP3) at the Faculty of Computer Science and Media, which has been researching the application of additive manufacturing processes in the context of traditional printing and packaging technology for many years.

Ausbildung für Forschung und Industrie der Zukunft
Lehre und Ausbildung bilden einen zentralen Grundstein des Forschungsbereichs AM³. Der Studiengang „3D-Druck & Funktionale Oberflächen“ bildet gezielt junge Talente aus, die für Forschung, Entwicklung und den erfolgreichen Technologietransfer in die Industrie benötigt werden.
3D-Druck ist eine Schlüsseltechnologie der Zukunft, mit der sich komplexe Strukturen von Mikrobauteilen bis hin zu großskaligen Anwendungen wie Filmkulissen oder technischen Komponenten realisieren lassen. Durch den schichtweisen Aufbau entstehen Geometrien, die mit klassischen Verfahren kaum oder nicht herstellbar sind. Gleichzeitig ermöglicht die additive Fertigung einen ressourceneffizienten Materialeinsatz, da nur dort Material verwendet wird, wo es funktional erforderlich ist.
Im Studium wird die gesamte Prozesskette von der Konstruktion über die Materialauswahl bis zum fertigen Bauteil vermittelt. Studierende lernen, wie unterschiedliche Werkstoffe kombiniert und Druckprozesse gesteuert werden, um funktionale und intelligente Systeme zu entwickeln. Ergänzend wird das beschichtungstechnische Know-how des 3D-Drucks auf 2D-Anwendungen übertragen, etwa für funktionalisierte Oberflächen, gedruckte Elektronik oder medizinische Anwendungen. So entstehen Lösungen für Bereiche wie Verpackungstechnik, Elektronik und Medizintechnik, in denen präzise aufgebrachte Schichten eine zentrale Rolle spielen.
Der Studiengang vermittelt damit umfassende Kompetenzen zur Entwicklung und Optimierung additiver 2D- und 3D-Druckprozesse in der industriellen Anwendung. Diese Kompetenzen sind für die Weiterentwicklung der additiven Fertigung von entscheidender Bedeutung, da sie die Grundlage für innovative Materialien, stabile Prozesse und übertragbare industrielle Anwendungen bilden.

Development of a system for planning and osteosynthesis in orthognathic surgery based on anatomically preformed osteosynthesis plates and planning software
Within the project, a system for comprehensive planning, simulation and surgical treatment in orthognathic surgery is being developed. A central component of this is three-dimensionally preformed osteosynthesis plates for each area of application in orthognathic surgery of the human upper and lower jaw as well as the chin area, which enable simple and reliable intraoperative implementation of surgical planning.

Generative production of multi-channel tubes for peripheral nerve regeneration
Until now, the healing of defects in the peripheral nervous system has had limited success due to the complex anatomical structure of nerves. The "Multichannel Tubes" project aims to use a new hydrogel material and generative process to break new ground in the production of an implant that will support the body's own regeneration of nerve defects in a targeted and better way.
