nextGen3D: Development of 3D printable polyolefines


    In the nextGen3D Project, CTO focuses on the development of 3D-printable polyolefines. The content of the project ranges from analytics of currently available filament types, to tailor made polymers up to the adaption of the printers hard- and software by project partners.
    Currently fused filament fabrication (FFF) for industrial relevant printers is limited to only a few materials. Polyolefines have valuable benefits compared to commercially available materials. They can excell them in point of impact stress, temperature stability, material durability; furthermore they are already in use in a vast number of applications worldwide and highly available at rather low prices.
    Considering material science the analysis are used to gain fundamental knowledge of the materials structure-properties relationship, in order to facilitate the printability of polyolefine grades. Polyolefin filaments are produced by the means of labscale compounding and benchscale polymerisation. These are then processed by an optimized printerhead and the results verfied with suitable testings geometries. The characterisation of printed testgeometries will then be done via optical inspection, impact stress and tensile testing as well as profiling ot the surface structure. Furthermore an inline inspection of the printing process can be realized via thermographical analysis and NIR spectroscopy, so one can gain knowledge about the about the adhesion quality of the layers and the temperature gradient of the surface.

This project is funded by the FFG:
