To improve the rough finish on the seams of your 3D prints, you can try adjusting the retraction settings in your slicer software. Increasing the retraction distance and speed can help reduce oozing and stringing, which can contribute to the rough finish. Additionally, optimizing the temperature settings for your filament and adjusting the print speed may also help in achieving a smoother seam. Experiment with these settings to find the best combination for your specific printer and filament.
