| Résumé : |
Additive manufacturing processes count as future-oriented manufacturing techniques. Numerous studies and award-winning demonstrators underline the interest of the industry. Nevertheless, up to now there are only a few plastic-based applications with significant quantities. Today, screw-based additive manufacturing is a solution for the economic and technical challenges and has the potential for series production. |

- Using strand shapes to systematically influence anisotropy
- Why does 3D printing plastics need metal ?
- Automated production of hybrid parts
- Approach to analyze the mechanical properties
- Mechanical properties at an optimal level
- Figure : The bicycle frame (600 g, produced in 80 min) is printed directly onto a metal sheet. This combination unites the advan-tages of two worlds
- Fig. 1 : Increasing nozzle diameters have a positive effect on the anisotropy of mechanical properties in the part
- Fig. 2 : Test set-up : variothermal fixture in production area of a SpaceA manufacturing unit, temperature load cycle and test specimen geometry
- Fig. 3 : Maximum load at different insert temperatures.This demonstrates the strong bond between plastic and metal over a wide temperature range
- Fig. 4 : Force-deformation chart of the tested specimens. The hybrid structure increases the stiff¬ness and strength compared to plastic-only test specimens
- Fig. 5 : Testing of the hybrid part: initial position (force applied to the metal component on the left, force applied to the plastic component on the right), maximum deflection of the test specimen and failure with fracture mode (insert temperature 175°C)
- Fig. 6 : Test in starting position (force application to the plastic component), maximum deflection of the test specimen and failure with fracture mode (insert temperature 220°C)
- Fig. 7 : A modular plant strategy allows scaling (here the largest model SpaceA 2000-500-5) and integration of all known automation concepts |
