Résumé : |
In additive manufacturing the material selection plays an important role for producing dimensionally accurate parts. Akro-Plastic developed a method to quantitatively assess warpage in additive manufacturing with pellets, which shows the influence of the material composition and the process parameters in an application-oriented manner. |
Note de contenu : |
- Warpage takes effect during the process
- Manufacturing-oriented quantification of warpage
- Carbon fiber reduces warpage effectively
- Importance of processing parameters
- Fig. 1 : Warpage can already be an issue in the build process
- Fig. 2 : Dimensions of the test specimen and method of evaluation
- Fig. 3 : Image processing for the computer-aided evaluation of warpage
- Fig. 4 : Carbon fibers reduce warpage more than glass fibers
- Fig. 5 : The warping behavior can be optimized by the choice of polyemr and fiber content
- Fig. 6 : Fiber orientation is crucial for warpage and can be influenced via the process
