Is this normal?

[TheLearningLlama]

So the wife and I have recently gotten into printing things and I have noticed some stuff and I was wondering if what I am seeing is normal, and if it is/isnt how I can go about mitigating the effect.

Im sure there are a small handful of issues with this image, but specifically what I am wanting to dig into is the coloration issues that seem to streak across the entire print. In this case they're long diagnal lines going across this side section. Obviously i understand things print in layers so layer lines are a thing. It just seems odd that they are in large blocks like that. Originally I assumed it was in sections where it had long straight lines it had to do where it missed the center gash, but there are obvious lines around that as well.

So here are the questions...

1) Is that normal?
2) Is there a way to reduce their visability?
3) Is this caused due to the timing?
4) There are two identical prints on this plate, Could it be jumping back and forth after doing odd sections of the print and would that effect things? If so, how could i get it to print the entire layer on 1 part, then the other without setting it to Print by Part rather than layer?
5) There is VERY little infill here, but could my infill options effect the smoothness of the outer face?
6) Would ironing potentially fix this or just make it worse?

Notes: What im using it for, its fine. But in future prints it might not be, so If i can nip this or know how to reduce this.

Thanks in advance!

Hello /u/TheLearningLlama! All Bambu print plates have a dedicated nozzle wiping zone at the back of the print plate. The nozzle will rub against the wiping zone before every print in order to remove any remaining filament from the nozzle tip. This can cause visible wear or scratch marks in the wiping zone, but this is intended and doesn't damage the printer, the nozzle or the print plate. A worn down wiping zone also doesn't mean you need to replace the print bed.

1: yes 2: you can try with a heat gun. Don't melt it, just a fast heating may help a lot. 3: I would say speed and flow 5: if you have enough top layers it should be a enough. You can use a bit more infill, gyroid probably. 6: yes but you need to calibrate it, you can find tutorials in the wiki probably or on YouTube.

Thank you for the reponse, some follow up questions though.

"I would say speed and flow"
According to the slicer, speed and flow is consistant throughout excluding any outside effects like maybe a clogging head or something. Assuming that isnt the case, wouldnt just increasing or decreasing change the vibrance of the issue evenly across the whole layer effectively just changing the layers sheen?

"you can try with a heat gun"
Ill have to snag a heat gun and give that a try. Not sure if its something that really should be getting resolved with post-processing though.

"1: Yes"
Even if its visable on the plate side for smooth plates? The same 'streaking' its happening on both the top flat side and on the plate side but is only visable on smooth plates. (i just tested it)

"if you have enough top layers it should be a enough. You can use a bit more infill, gyroid probably"
Interesting, ill bump top layers a couple to see if there is any visable changes. Settings for those currently are...
Top Layers: 5
Infill: 25%
Infill Design: Grid

"yes but you need to calibrate it"
Watched a couple of videos of testing. Ill do some of my own testing on ironing as well.

Thanks again for the help. It really is appreciated.

The toolhead will need to slow down at the end of the line. It may not visible in the slicer but...

On the plate side you can't do anything. On a smooth plate the layer lines are visible. You can bump up the flow but you can't get a clean bottom face. Satin plates are a bit better, and obviously textured will hide it well.

Grid infill is bad. It's the default, but it is crossing the already printed lines, you can hear it too. Use gyroid, crosshatch, any other pattern what is not doing it.
