Hello, X1C with AMS here doing multicolor print with .4mm nozzle.
The picture is zoomed in on a pretty small surface about 12mm wide edge-to-edge and as a reference, the red border around the white background is one line width (.4mm). As shown, the transition between back and white is not exactly clean, looks like leftover fuzz. I tried printing black before white then white before black but got a similar mess.
Any suggestions to clean this up?
Increase the flushing volumes.
I’m not seeing color bleed which would benefit from increased flush volumes, I’m seeing fuzz or hair left behind by the nozzle which later gets trapped under the new color being printed. The model is printing face down so the picture is the bottom layer.
I’m circling here the trouble areas:
Top picture printed black then white, bottom white then black.
Just gathering some additional information to better understand the issue.
There’s a few settings that you should try from my print profile for this coaster. Coaster: “Not my circus, not my monkeys” by jetpadMakerWorld: Download Free 3D Models and for this one

The second one I spent more time on trying to improve it but still didn’t resolve all the issues.
The settings that I think helped were
Yes , Yes , Yes.

Thanks. Some of those I already have and I’ll try the rest today.
Have the colours been painted ? i found the printer (A1) will pick up every wobbly line or miss spray and print it as it is (shown in geometry)
, unless they have a border to infil (extruded parts like lettering)
Each color is a separate STL part. Lines are straight.
I think the black and white bits that are out of place are inadequate purging, or filament stuck to the nozzle and falling off.
I doubt the nozzle is creating the wavy red/white transition, which is probably the result of using a textured plate. Filament is pressed into the randomly placed “hills” and flows in the direction of the slope.
Both of these images are seperate objects ( text objects ) that have been individually painted using the infil tool
Which of the above tools were used on yours ? circle (spray) perhaps ?
Was the plate clean? Maybe the small specs of black were left behind from a previous print.
No painting tools were used. The model has been broken down in 3 parts in CAD (3 different STL files). Once imported in Studio, each part is assigned a different filament.
So color assignment is not my issue, it’s fuzzy hair being dropped when printing.
I should have mentioned this is all printed in PA-GF so that could have something to do with it. I tried using ABS as a comparison and it comes out perfect.
I’ve had some time to try all the suggestions I received with little improvements. The most improvement I got was by changing the bottom surface pattern to Monotonic as it eliminates a lot of retractions. Printing from inside to outside also helped some.
I’ve second guessed my calibration results and redid them but they were right. I’ve done a stringing test which I rarely do and my settings were fine.
Filaments were dried and kept in a dry box measuring 10%RH.
I’ll post whenever I get it solved.
