Functional Nanomaterials Chair


Additive manufacturing has been on the rise for the last 10 to 20 years, since it offers unique workpieces and parts to be constructed. In our German RepRap X400 Pro printer we can print thermoplastic materials from filament such as Acrylonitrile Butadiene Styrene (ABS) in black with High Impact Polystyrene (HIPS) as support material, as well as special materials such as Thermoplastic Polyurethane (TPU) which exhibits rubber like properties and iglidur® which is a special low friction material.

The highest achievable resolution is 0.2 mm lateral and 0.1 mm in z-direction. The slicing software we use is Simplify3D.

We also have the Form 2, a stereolithography printer (SLA) from Formlabs and a masked SLA printed from, the Elegoo Saturn. With these, much higher resolutions of 0.025 mm lateral and 0.025 mm in z-direction can be achieved. The Formlabs uses proprietary materials, the Elegoo Saturn can print with every MSLA resin you can find on the market.

Additionally, we do research in direct ink writing (DIW) of gels like ceramic slurries, microparticle-laden inks or hydrogels. For these we have two 3D printer setups that use cartridges and plungers to print parts with a resolution of 100 µm lateral and in z-direction. Our Velleman printer is equipped with a custom-made syringe holder

The Printopeww is equipped with a 60W Fiber coupled CO2 laser = 10.6 µm) that we use to fuse even ceramics like ZrO2 and Glass.
