I cannot get de outerwall smooth. And the bottom inside looks also bad.
Printed with new petg and pla.
I printed another print (not round) with a thin wall and this looks perfect.
That’s my response on that post about silver PLA. I tried the suggested values and they made the print look bad. I changed it back to the default, prints look good again. I did not try it with the bronze. It may work for you, my silver is a year old by now.
If the cup shape is only 1 wall thick, there may not be a way to print it cleanly, it may have been intended for resin printing which can do walls that thin. The following comments are just me thinking out loud. You could slow the printer way down, say in the 40-70 mm/s range. Print at the smallest layer height your current nozzle can go. Switch to the smallest nozzle your printer supports. If it’s 2 or 3 walls try setting Quality/Advanced/Order of walls to inner/outer/inner. You may also have to play with temperature.
I usually randomize the Z seam so I don’t get a big unified seam defect. Tried scarf for the first time last week on a print where I forgot to randomize the Z seam. I know which corner of the print was chosen by the slicer for the seam. Cannot detect it visually. The print effectively has no seam. Good stuff.
