| Résumé : |
In a joint project, the Fraunhofer Plastics Technology Center Oberlausitz, working together with the University of Zittau/Görlitz, as well as the industry partners KraussMaffei and Elbe Flugzeugwerke, has enhanced an extruder-based method for additive manufacturing of large-format plastic parts using a flexible melt pipe. Besides a proof of concept, there was also a focus on studies into how the parameters of the experimental set-up influence the output material resulting in the highest possible component quality. |
| Note de contenu : |
- Decoupling the extruder unit from the 3D printing nozzle on the robot
- Pressure fluctuations in the melt pipe
- Influence of the material on the layer stability
- Figure : Thermal analysis of the deposited plastic strand in the large-format, extruder-based 3D printing process
- Fig. 1 : The extruder is coupled to a flexible melt pipe with the print head fixed on the industrial robot
- Fig. 2 : The innovative print head permits pressure and temperature measurement of the plastic melt
- Fig. 3 : The application performance of the Collin extruder (melt pipe DN16, printing nozzle 6 mm) has a linear deposition characteristic depending on the speed
- Fig. 4 : The fiber length and the fiber content influence the layer stability and thus also the component quality
- Fig. 5 : The residual temperature of the deposited plastic strands fundamentally influences the component strength in the build direction (Z-direction) |
