Greetings, esteemed individuals of the Internet,
Thus far, all of my prints have been satisfactory. Regrettably, I have encountered a predicament with my most recent print that eludes my ability to resolve.
Upon observing the image provided, one may discern peculiar textures present on the uppermost layer, resulting in a lack of the desired smoothness typically exhibited by my previous prints.
I humbly request any potential remedies or solutions to rectify this issue.
Looks like the infill pattern. Try using a different infill pattern or increase the top layers.
Looks like grid infill, which crosses itself on the same layer, creating raised bumps at the intersections, which show through thin top layers. The nozzle can also hit the bumps, in some cases knocking the model loose from the plate. Rectilinear (alternating directions on adjacent layers) or gyroid infill would avoid the problem.
Lightning infill will also create a more random-looking pattern and generally prints a little faster albeit at the cost of strength but for a thin part like this, it likely wouldn’t make a difference.
Personally for parts that are under 3mm, I go with layer heights at 5 or more creating a very solid part. But that is a personal preference and uses more filament and takes longer to print but on a thin part, that time may be negligible.
I would like to express my gratitude for the prompt responses received.
The modification of the infill has proven to be successful. By adjusting both the infill and the layer height of the top layer, the issue has been entirely resolved.
I extend my sincere appreciation for the assistance provided!
