I’m trying to print some name cards which are relatively flat. The overall surface of the card looks fairly decent. However, it seems that in the smaller areas the print quality goes down. I think there could be two reasons for this but I’m not sure how to solve it (if it is solvable). The first reason is that the area maybe gets too hot, since the nozzle is hovering over the same area for a longer time than the larger areas. The second reason might be that it reaches this point later, thus maybe having a different surface temperature on the previous layer? Please note that I’m a beginner, so it may very well be something else.
I’m using the A1 Mini with a 0.2mm nozzle and PLA matte and PLA metal. I’ve tried many different settings on the printer: the default 0.06mm high quality + default filament settings (very poor results), but also tried recommended settings such as lower speed, and increasing flow rate. Currently, the settings that work best are as follows:
QUALITY:
Layer height: 0.05
Line width - default: 0.18
Line width - Initial layer: 0.22
Line width - Outer wall: 0.2
Line width - Inner wall: 0.2
Line width - Top surface: 0.18
Line width - Sparse infill: 0.19
Line width - Internal solid infill: 0.19
No ironing
Wall generator: Classic
STRENGTH:
Wall loops: 1
Surface patterns (all): Monotonic
SPEED:
Initial layer: 16
Initial layer infill: 28
Outer wall: 60
Inner wall: 70
Sparse infill: 45
Internal solid infill: 70
Top surface: 70
For the filaments I used the manual flow calibration and additional testing and now have the Flow Ratio at 1.05. I’m interested in increasing it more but then it will be outside the recommended values. For Cooling: no cooling first 5 layers, and 80% to 95% speed.
Increasing the fan speeds improved the situation a bit. However, with 95% fan speed and lower nozzel temp (210 instead of 220) I get horrible results.
Any help is appreciated!
