Any advice to get a full curved surface without gaps? I have been able to get better results by increasing resolution (decreasing layer height) as the printer approaches the tops of curved surfaces or spheres. The same phenomenon occurs when printing spheres. The only thing that helps is to gradually decrease layer height down to 50 microns for the top of the sphere to successfully print. It was manageable (the top portion of the outside looked good but the top portion on the inside had imperfections.) Any other tips? How are you all printing cuved surfaces that have overhangs or spheres? For a while, to decrease time, I was just printing without the top portion included, but now I want to print the full curved surface or sphere with good quality. Also, for the pic shown, I am printing with full supports inside the circular shape and below it (note the bottom is actually shown on the top of this picture). It's also at a rather low 0.3 mm layer height. It's almost as if it is a layer height/resolution/slicng issue because you can only capture so much of a curved surface with a finite layer height. This may just be a problem with 3D FDM printing in general, though. Any helpful tips would greatly be appreciated. Also, my printing nozzle is 0.4mm in diameter. I could probably buy a smaller nozzle for more resolution, but I am wondering if anyone else is able to print high quality curved surfaces/spheres with their stock Robo 0.4mm diameter extruder. For this part, it has to be printed vertically, which is why I was using supports. I know there are multiple ways of printing this. I could just print this as a seperate feature and manually add it to my print later (rework). For the purposes of this post, I would just like tips on printing better curved surfaces/spheres. Thanks in advance. UPDATE: NEW QUESTION ADDED SO OTHERS CAN SEE IT MORE EASILY This next question relates to printing spheres in Simplify3D or S3D. I figured I would add it to this thread, though. I often see the slicer starting a layer in open space. I don't know why they don't have it set to just keep going around the edges. You would think it would make more sense, like how the spiral vase setting goes. Unfortunately, you can't have supports with that setting. I am trying to make a sphere that is several inches in diameter, and I would rather not have to print a support just for the very last tip of the sphere. How do you all handle this? Have you seen this occur?
