Additive manufacturing

In the area of additive manufacturing we concentrate on the extrusion based technology of thermoplastic materials. For the development of filaments, with defined properties, we can rely on the know how from compounding, the material measurements and also extrusion. besides of the material the great number of printing parameters and the design are from great importance for the quality of the parts.

What we do
  • Material development and testing
    Highly filled and abrasive fillers
    Filament extrusion
    Print tests

3DMultiMat - 3D Printed Functional Multi-Material Components


The goal of this three-year (2020-2022) project is to develop a sustainable, stable and flexible manufacturing process for complex multi-material (metal-ceramic) components shaped via extrusion-based additive manufacturing followed by sintering. Two material combinations are investigated. In the first material combination electrically conductive and insulating sections of ceramics are combined. The second area is the manufacture of metal components with sections of magnetic and non-magnetic properties as well as electric conductive and non-conductive properties. 

The Institute of Polymer Processing at the Montanuniversitaet Leoben is leading the project, which has received funding from the Austrian-Chinese Cooperative RTD Program by the Austrian Ministry for Transport, Innovation and Technology (bmvit) and the Austrian Research Promotion Agency (FFG). The Austrian industrial partner is RHP Technology and the Chinese partner is the Institute of Metal Research at the Chinese Academy of Science in Shenyang.

In the flag ship project Addmanu the chair researches the thermal and rheological properties of the filaments for 3D printing and correlations between these properties and the printed parts should be found. With the optimized process parameters the quality of the printed parts should be increased. With the project partner Hage alternative feeding devices should be developed.

The FFG CORNET project AM4I (Additive Manufacturing for Industry) focuses on quality-assured 3D printing processes for the production of technical components from high-performance polymers and hybrid constructions in the SME environment.

The core idea of ??the project is to fit additional manufacturing technologies (Fused Filament Fabrication (FFF)) for industry in terms of quality, time and costs. Metal-, ceramic- and polymer-printing are taken into account and the entire value-added process of material - print - component is illuminated.

The Chair for Polymer Processing deals with three specific case studies from the automotive, filament extrusion and orthopedics.


In this project the additive manufacturing of ceramic should be developed for consumer goods and medical devices, which are impossible to produce with other techniques. The chair develops ceramic polymer compounds, but also electrically conductive materials for fused filament fabrication. These should be printed at the same time and after sintering form a compact part with customised and multifunctional components.

This project has received funding from the European Union’s Horizon 2020 Research and Innovation Programme.

The efficiency and reliability of power electronics depends very much on the temperature.  Growing  demands to reduce the size of electronic components leads to the use of new technologies and materials, while ensuring efficient cooling and economical production.

The ECOPRINT project addresses these needs by developing new metal-polymer and metal-organic hybrid compounds for use in additive manufacturing. The development steps are the functionalization of metallic and ceramic powder particles by atmospheric plasma or wet chemical processes, incorporation of these powders into high performance polymers, optimization of filaments, modification of equipment for processing by additive manufacturing and investigation of new materials for high temperature applications.

Flexible production via 3D printing of sintered metal and ceramic complex parts

The goal of this two-year (2017-2019) project is to develop a sustainable, stable and flexible manufacturing process for complex metallic and ceramic components shaped via extrusion-based additive manufacturing. Among the applications of this process in the project are the manufacturing of monolithic catalysers for air purification and components for the mobility industry.

The Chair for Polymer Processing is leading the project, which has received funding from the Austrian-Chinese Cooperative RTD Program. The Austrian industrial partner is RHP Technology, and the Chinese partners are the Research Center of Nano Science and Technology at Shanghai University and the Shanghai Industrial Technology Institute.








The core idea of ??this two-year project is to print biofiber-reinforced polymers on free-form surfaces along the flow to maximize the components.

The Chair for Polymer Processing, together with the Kompetenzzentrum Holz Wood K Plus (consortium leadership), has received funding for the project "Natural3D" from the call "Austrian-Chinese Cooperative RTD Projects".

The other project partners are FH Technikum Wien, Hage GmbH CoKG, Ecoplus, Thermoplastkreislauf GmbH, HeadSport GmbH, Haratech GmbH and Shiner3D GmbH.

NextGen 3D

The FFG cooperation and innovation project NextGen3D deals with the materials development for the industrial additive manufacturing. Polyolefins should be developed and optimized for extrusion-based additive manufacturing, as such polymers are not commercially available. The impact strength and the heat deflection temperature of the polyolefins are higher than the normally used polymers for extrusion-based additive manufacturing.

In addition, polypropylene is to be tested for filament production, which is characterized by a higher toughness, good modifiability, lower moisture absorption and better temperature and chemical resistance compared to commercially available filaments of ABS or PLA.




The goal of this EU funded project is the development of a resource efficient manufacturing route for Rare-Earth magnets. At the chair a polymer metal compound is developed, which should be used on fused filament fabrication printers (FDM printer). The printed parts are put into a solvent to remove the first polymeric compounds and afterwards the parts are sintered to get homogenous rare earth magnets.

Project funded by the European Union’s Horizon 2020 research and innovation programme.
