In many technical applications, laser-sintered components still have inadequate surface topology. New methods of cost-effective and geometry-independent surface finishing of the laser-sintered specimens are therefore needed.

When printing high-performance polymers such as PEEK, stresses occur in the component due to the relatively high printing temperature and the changes in the material structure. In the Smart Printbed project, a system was developed to minimize these stresses and also save electrical energy.

For Extremely Soft Applications

Combining additive manufacturing with a digital, simulation-based design process makes it possible to develop even highly complex extrusion dies in a time-saving and economical manner. Experts from the Eastern Switzerland University of Applied Sciences and ETH Zurich have successfully applied this technique using the example of a novel co-extrusion die.

Fiber-reinforced plastic components, including those for load-bearing areas, are established alternatives to metals in vehicle construction. It is not just their low specific weight that makes them interesting, but also their acoustic properties, which reduce noise transmission.

Medical Applications of Additive Manufacturing

Marbling is often a real eye-catcher in plastic components. However, the effect is difficult to create and there are some pitfalls when it comes to reproducibility. Novel nozzles for injection molding machines in combination with a special dosing technology allow marbled molded parts to be produced far more easily in a much more robust process.

Exciting Design instead of  Exciting Manufacturing

Hybrid production chains have been increasingly in the spotlight in recent years. This also applies to the combination of conventional manufacturing and additive processes in tool construction. With the example of an injection molding tool, it is shown how mold inserts produced by additive manufacturing can greatly shorten cycle times, and thereby significantly reduce unit costs. The important thing is to find a suitable combination of processes from the variety available.

New Possibilities for Use  in the Human Body

In no other field the possibilities and advantages of 3D printing are more pronounced than for medical devices. With the right high-performance materials, complex patient-customized implants can be produced that medical doctors are using to push the boundaries of the possible – for the benefit of patients.

Quick Way to Find the Right Adhesive

For the Institute of Plastics Processing (IKV) at the RWTH Aachen University, Germany, 2020 is an anniversary year in three different ways. The RWTH Aachen University is celebrating its 150th anniversary, and is marking the occasion, by hosting the International Colloquium of Plastics Technology for the 30th time – with special feature on the previous day. A preview of the celebrations.

Shape-changing structures (smart structures) are able to change their shape in response to external stimuli. The change of shape is self-induced and requires no artificial energy input. In view of the increasing demand for efficiency and resource conservation, shape-changing (smart) materials offer a sensible approach to integrating functionalities into a component without giving rise to additional energy and material costs. Even greater sustainability is achieved if the components are produced from bioplastics.

3D printing is a fast-growing market, opening up completely new product and manufacturing options for customers and industry. The newly developed SEAM process significantly extends the options for the efficient manufacture of printed components. An impression of this is conveyed by the example of a fiber-reinforced clamping fixture.
