I am trying to print some 20mm ball shapes, the bottom is flat 10mm diameter.
I want to print these in ABS to use in swivel ball mounts and I have cut the bottom off and put a hole into it for a heat set nut.
So far the prints are failing mostly due to really bad surface on the bottom round area and some by detaching from the bed and the edges curling up.
Printing with 110c bed for 3 layers then 95c (I have found this works well for most of my ABS prints) Hotend at 245c.
I was printing at 80mm/s but am now trying at 55mm/s and I am trying with manual support all around the bottom half (using Simplify 3D)
My printer is in a heated chamber always around 40-50c.
Nozzle I have right now is .40 (I have some .35 and also have some .25 on the way). Layer height is .12mm also tried .15
I know I probably just need more trial tests with various settings but just wanted to see if anybody has any specific ideas to help print a ball shape.
I need it to be fairly smooth all over and the top is printing perfect but the bottom half is pretty ragged.
I guess I could split it in half and then glue back together but just thought I would ask as it seems like this should be possible as is.
