Which printing parameter has an effect on the creation of voids and from those parameters which one has a significant effect on voids in the FDM?
I think that this question is difficult to answer because it depends strongly on the application. According to this, the production of voids is strongly dependent on the geometry and makes different demands on the process parameters.
For example, smaller voids can be produced very well with standard process parameters. However, if the voids are elongated, a large unsupported area is created. For this purpose, the 3D printer can hardly bridge this area, so that process parameters like cooling and printing speed, depending on the flow, are important.
The infill percentage is one of the crucial parameters to avoid voids.
First is the material, and the second is toolpath parameters such as bead height, bead width, overlap, raster angle and build orientation. All of these parameters and the speed of the nozzle have an effect on the creation of voids in FDM.
@ all thanks for your timely response , all the above mentioned parameters have a significant effect for the creation of voids but as per my finding layer height and printing speed has the higher effect than raster width and air-gap between adjacent raster's.
If you have further comments and suggestions I'm here to learn from your knowledge and expertise.
