Arburg Plastic Freeforming is predestined for the additive manufacturing of medtech components. The associated Freeformer-type additive manufacturing systems process the same plastic pellets that are used in injection molding. That makes the open systems very economical to use.

In the AKF process, resorbable original materials such a plate-implants similar to bone, can be manufactured. They are gradually replaced by endogenous tissue

Outstanding 3D Achievements

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.

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.

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.

Ensuring Quality in 3D Printing

IKV develops process for non-planar additive manufacturing with a jointed-arm robot and screw extruder.

The IKV has developed a process for non-planar additive manufacturing with jointed-arm robots and screw extruders. Compared to conventional additive manufacturing, the surface roughness can be reduced by up to 76 %.

Through the layer-by-layer production of plastic parts, additive manufacturing offers a high level of geometric freedom. Components with complex geometries and internal structures can be quickly manufactured without any set-up operations. However, these layers have until now always been planar in form and aligned parallel to the construction platform. Compared with other manufacturing technologies, layer-based processes thus have disadvantages with regard to the surface quality of the parts, caused by the step effect. Because of the lower load resistance in the build direction (attributable to the adhesion between the individual layers), the mechanical properties of the component are also anisotropic. In order to overcome these difficulties, a process for non-planar additive manufacturing with variable layer thickness was developed at IKV. With this method of path planning, it was shown that the surface roughness can be reduced by 76 % compared with conventional additive manufacturing.

With non-planar additive manufacturing, the exact form of the component and the existing load cases are taken into account when calculating the machine code. The layers generated in this way can be freely arranged in the space and can be curved. This applies both to the layers on the outer sides of the components for producing high-quality surfaces and for all layers on the inside of the component. The latter allows the specific exploitation of the technology-related anisotropy through the load path-oriented design of the individual plastic strands. The variable layer thickness, which is achieved through the specific variation of the material output, allows a gap-free transition between different curvatures and orientations.

Larger Parts, Material Variety And Accelerated Production

In order to increase the size of the part, the diversity of materials and the production rate, the implementation of non-planar path planning on a large-volume additive manufacturing screw extruder – IKV‘s hybrid production cell – is being examined in a research project. The machine‘s robot arm allows a large build volume and the use of three additional freedom levels, which are utilised to adjust the extruder according to the gradient of the component to be manufactured. In this way, the quality of the part can be further improved. In addition, the possibility exists of adjusting the load path with large-volume additively manufactured parts. By processing fibre-filled standard granules, which show very good mechanical properties in the strand direction, in combination with the specific orientation of the individual strands by non-planar additive manufacturing, the technology-related anisotropy can be exploited. This technological lead is especially relevant in the industrial application of additively manufactured parts.
