Problems with unclean top layer with Prusament ASA
Hi,
I am trying to print a part with Prusament ASA and am having problems with the top layer. I am using a MK3S+ with a rough plate in an original Prusa Enclosure V2. To increase the adhesion of the stick I use a Magigoo stick. My enclosure is heated with a regulated cabinet heater. I always preheat the enclosure to 40 degrees Celsius before printing (only by bed and enclosure heating). I have no problems with adhesion - but my top layer looks very bad. As slicer I use PrusaSlicer 2.6.0 with the original filament profile for Prusament ASA. As usual, I printed the part with Gyroid Infill and monotonic pattern. Unfortunately, the part looks very bad.
.
I reduced the size of the part and printed it several times with different parameters. The best result was achieved with rectilinear infills and Archimedean chords - but even that was not perfect !
Now my question to the experts: What am I doing wrong? How can I improve the quality of the print?
Thanks,
Joerg
