I am trying to print a part from black PLA 'PolyMax'. Problem is that it must be printed as shown in the photo (conical part at the bottom).
You can see the result in other photos. Surfaces are not good, they are rough and not smooth. What can be done to print this part with a good quality?
Some settings that I use:
Nozzle diameter: 0,4 mm;
Extrusion Multiplier: have tryed 0,9 and 1,0, does not make a difference;
Primary Layer Height: 0,08 mm;
Top/Bottom Solid Layers: 5;
Infill Percentage: 50;
Printing speed: have tryed 1800 mm/min and 2100 mm/min, does not make a difference;
If anybody could help with this print, I would be very grateful.
P.S. The top surfaces are good.
