I designed a box with cornered edges, the edges were smooth in Fusion 360. But when it is 3d printed, some abberations appeared at each corner like as in the picture below. How can I overcome this and I need smooth corners. And what might be the reason for rough surface?
Most likely reason is the printer isn't tuned properly. Second is the slicer settings. Unlikely is Fusion at fault. Post your stl from Fusion, so others can verify it.
There are SO many reasons those curves might not be smooth- form ambient temperature to humidity exposure to printer settings to stepper motor/drive deficiencies Better hope it's not the last, as you have some degree of control of the others. Have you test printed a similarly curved surface to compare and begin isolating the problem?
Can you post a picture of the aberrations? Just use the Photos button at the top of this window and it will appear as part of your post- attaching the image below requires us to perform extra steps to see it.
I don't see any excessive truncating of the corner profiles. If you zoom in in Fusion 360, you can see some, but not as much as the render in your first post shows. You can increase the resolution in the STL creation dialog to see if that helps.
I actually printed the part and still there is rough surface on the corners, but the design is smooth in fusion.
There's no way for us to really know which it is- accurate faceting or byproduct of printing process -without images of the part AND a known-good curved part printed in the same orientation. How about starting with some pictures?
Besides the export parameters in Fusion 360 and the resulting number of facets in the stl file. In what direction are you orientating the part on the print bed. If the image shows the print orientation and the lay height is to large it might be possible that your printer is not able to print that "angel". Might be better to lay it flat on the bad (if your design allows that).
