Therefore, the microstructure and the strength of the hybrid joints manufactured by LPBF or vacuum brazing were examined and compared to solid material and joints of similar material. The aim of this research was to investigate the hybrid joint properties of LBPF and conventionally casted 18MAR300 nickel maraging steel depending on the manufacturing process and the heat treatment condition. Today, constructors have to select the most economical joining process with respect to the individual field of application. Joining of an additively manufactured complex part to a high-volume part made of conventional material is a promising technology to enhance economics. As a result, the ANSYS module to work on should be chosen depending on the job's goal as well as the CAD geometry's complexity.Įven though the buildup rate of laser powder bed fusion processes (LPBF) has steadily increased in recent years by using more and more powerful laser systems, the production of large-volume parts is still extremely cost-intensive. It can be inferred that the two modules produce similar results for models with fine mesh. This article compares two ANSYS modules for the purpose of validating results. Simulations using computer-aided engineering (CAE) are critical for achieving an effective and cost-effective design.

CCC, on the other hand, has a more complicated design procedure than traditional channels. Using CCCs can reduce thermal strains and warpage while also improving cycle time and achieving a more uniform temperature distribution. The major reason for this is that CCCs may follow the courses of the molded geometry, whereas typical channels created using traditional machining processes cannot. In the injection molding process, CCCs provide higher cooling performance than standard (straight drilled) channels.

The experimental results show that the hybrid tools withstand the high mechanical and thermal loads which occur during hot aluminum extrusion.īecause of recent advancements in additive manufacturing, fabricating conformal cooling channels (CCCs) has become easier and more economical. Numerical and experimental investigations revealed that the profile’s exit temperature can be reduced locally and controlled which leads only to a moderate increase of the extrusion force. A further novelty of the developed die is the isolated feeding of the coolant up to the target area, close to die bearings, where the cooling shall be localized. Here, the large volume but geometrically simple die part, the die bridge, is manufactured conventionally by subtractive methods, and the smaller part with geometrical complexity, the tip of the mandrel, is built-up on it additively by laser melting. Since, to date, the additive manufacturing processes are often accompanied with higher manufacturing time and costs in comparison to conventional subtractive methods, a new concept for a hybrid extrusion die is presented.

To prevent an overheating of the workpiece material and to increase the productivity in hot aluminum extrusion, the application of extrusion dies with conformal cooling channels manufactured additively by selective laser melting is known.
