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.

Production is becoming ever more flexible, diversified and decentralized. Without doubt, additive manufacturing processes make a crucial contribution to this, also initiating the transformation from production-based design to design-driven production. In this article, the 3D printing service provider FIT outlines a best-practice panorama of current technologies.

Over the four trade-show days in November, Formnext 2021 transformed the metropolis of Frankfurt am Main, Germany, into an international innovation center of global additive manufacturing and modern industrial production. At the plastics side, some of the focuses were on the manufacture of voluminous parts, the use of injection molding pellets as a material basis, and the processing of high-performance plastics.

Software Optimizes Properties of the Components

Researchers have developed software that can adjust important parameters during the printing process.

3D printers are a flexible way to produce components. Researchers at Technische Universität Kaiserslautern are also making use of this technology: In order to optimize the printing result for plastics, the researchers have developed software that can adjust parameters such as temperature and printing speed during printing.

In 3D printing, a component is printed layer by layer along a specified path. This technique allows companies to produce their goods without much effort. However, various parameters such as temperature, printing speed, printing direction, layer height and geometry of the component can influence the printing result.

At the Institute for Composite Materials headed by Professor Dr-Ing. Alois K. Schlarb at Technische Universität Kaiserslautern (TUK), the team is working on 3D printing technologies. One of the researchers‘ goals is to optimize the properties of the printed products. “Once a layer is printed, it cools down. When the next layer is applied on top of it, it has a higher temperature than the one underneath, and the layer underneath heats up again,” explains Miaozi Huang, research assistant at the institute. “This contact temperature or local temperature between the printed part and the part to be printed influences the quality of the seam or the weld.” This plays a major role in the properties of the product. In the finished component, this is a weak spot, especially if the local temperature was not high enough when the seams were created.

Optimally Exploit of the Material Properties

This is where the work of the engineers from Kaiserslautern comes in: The team has developed a software, which during printing ensures that various constants such as the temperature of the print nozzle or the printing speed can be flexibly changed – depending on the shape of the component and the plastic used. “The aim of our technology is to optimally exploit the material properties,” says Alexander Schlicher, who is involved in implementing the concepts at the institute. “Similar processes do not yet exist.” What is special about the software is that the researchers can flexibly change the parameters for each individual movement of the printing process.

They have already tested the new procedure in the laboratory. Two samples, one printed with conventional software, the other with the new technique, differ in their structure, as can be observed under the microscope. “There is also a difference in the properties, especially in the tensile strength across the direction of printing,” adds Miaozi Huang. “This method allows the weak points in the printed products to be eliminated.” For example, with this method it is possible to keep the contact temperatures between two strands in the optimal range for the respective moulded part geometry.

Such optimizations are important, for example, for increasing the service life of a component. The method used by the team from Kaiserslautern allows weak points in the plastic to be avoided.

The engineers will present their work at the Hannover Messe from 30 May to 2 June at the Rhineland-Palatinate research stand (Hall 2, Stand B40).
