Does FDM require post-processing?
But FDM/FFF 3D prints have a rough surface finish, the layer lines are clearly visible and more often than not these parts require post-processing. Many different post-processing techniques are employed and we will try to understand 8 such techniques for post-processing of FDM 3D printed parts.
What does post-processing do in games?
The so called post-processing is the process of applying filters and effects on an image of a game! In this process the game renderizes its images, however before it is sent to the monitor another rendering process will occur about the original image, then a lot of effects and filters will be applied directly on it.
Why is post processing important in FDM printing?
FDM 3D printing is best suited for cost effective prototypes produced with short lead time. Layer lines are generally present on FDM prints making post processing an important step if a smooth surface is required. Some post processing methods can also add strength to prints helping to mitigate the anisotropic behavior of FDM parts.
How does FDM and FFF 3D printing work?
FDM/FFF 3D printing involves extrusion of a polymer filament, heating it to its melting temperature and depositing the material in the required geometry to successively build the object layer by layer. But FDM/FFF 3D prints have a rough surface finish, the layer lines are clearly visible and more often than not these parts require post-processing.
Why are layer lines important in FDM prints?

How to post process a 3D printed part?
Priming and painting are one of the most popularly employed post-processing techniques for FDM 3D printed parts. Priming can be carried out only after the 3D printed part is sanded with a moderate grit sandpaper (close to 600 grit). After sanding the part, spray the primer onto the part in two separate coats.
