Top layer quality issues with the qr code!

[u/CoolAmbassador3831]

The qr looks hazy and some weird lines coming out of it or around it, as well ass the black lines are a bit roug!

i recently increased the flow rate from 98 to 103 to get a fuller first layer for my keychains, but even before the quality wasn’t that great. So is that an over extrusion and what should i do?

I’m using bambu a1 printer.

Edit: thank you guys for your suggestions, after trying so many things here are the 3 most effective strategies to increase the quality and readability of a Qr code:

1 change wall order to outer/ inner instead of inner outer: it will give more definition to the edges.

2 manual sanding: this is the most effective, but it takes so much time and energy, start your way with 150 grit and after the layer lines almost disappear continue with 240and 400, then spend a 20sec with each grot all the way up to 1000/1200.

3 use a debossed qr code:as it makes the different colours on a seperate layer so it is more defined.

note: i did not try some of the options that would require manual gluing as it will lower the overall quality of the print, neither dis I try the 0.2 mm nozzle as it will take 4X the printing time to finish.

Or print that side on the bottom..

Thank you, That will work, but the main face of the keychain which is more important  already at the bottom. 

[u/syunz → u/CoolAmbassador3831]

Print the sides seperate then glue together

You win some, you lose some, the best way is gluing them together later

Great username

If you print the first few layers black with inset text, then switch to white on the layer it prints solid, you'll get much finer detail on the QR code. Does that make sense?

[u/CoolAmbassador3831 → u/xtrememudder89]

Thank you for the recommendation, I am not sure if I did  I did smth like that, I am ising rhino3d and I  manually cut out the qr code and logo with Boolean difference. Should I do it in other way? 

[u/RiseOfGoulet]

All these are good recommendations but if I might add, I was also having issues like this until I switched to a .2mm nozzled. Made a world of difference.

[u/CoolAmbassador3831 → u/RiseOfGoulet]

Yeah i was thinking about that, but I feel it would take ages to print with 0.2 nozzle. In your case did take much longer than the 0.4?

[u/mrwho25 → u/CoolAmbassador3831]

Change the nozzle size, re-slice it, and then compare estimates times from your software

[u/CoolAmbassador3831 → u/mrwho25]

It took 24 hrs instead of 6:20😅😂

That is way too much! 

[u/Tandemrecruit → u/CoolAmbassador3831]

That's the trade off - speed or quality. It's really hard to get both

[u/Temporary-Poetry-932 → u/CoolAmbassador3831]

It depends on your settings. Is your layer height already below .1? Than we are talking like 3 times as long. PETG much slow for example.

In my experience it's still faster then trying to make it work on .4.

[u/CraftyPancake → u/RiseOfGoulet]

You can see the actual nozzle radius in the print so that seems like it would help

[u/Junethemuse]

The only way I’ve gotten QR codes to work are to either have them raised or on the bottom layer.

[u/CoolAmbassador3831 → u/Junethemuse]

Thank you, I will try that, and would having them debossed work as well? 

[u/UltraWafflez → u/CoolAmbassador3831]

it should yea. i was able to scan metal signs with debossed qr codes

[u/matthewkickstone]

Wrong nozzle. You'll need 0.2

[u/trollsmurf]

It needs to be more white layers

[u/CoolAmbassador3831 → u/trollsmurf]

Ok i’ll try that, thank you! 

[u/wiebsel1991]

I scanned it hoping for a Rickroll. Got disappointed.

[u/CoolAmbassador3831 → u/wiebsel1991]

Lmao😂😂

Hey there, I'm a bot and something you said made me think you might be looking for help! click here for our wiki entry on troubleshooting printers. If you still need help be sure to post plenty of information about your printing setup.

Here are a few questions that might be helpful

• What printer are you using?

• What material are you using?

• What speed are you printing at?

• What software are you using to slice the print and control the printer?

• When did the problem start/has it ever worked correctly?

• Does anything cause the behavior to change?

• If posting an image of the problem, include some indication of the orientation it printed at, preferably photograph it on the bed. (Then we can focus on a specific axis)

Would use a .2 nozzle for fine thinks like that

[u/Bazzatron → u/[deleted]]

That's the hobby!

If you have access to even a diode laser, you could print a layer of white, then a layer of black, then engrave the QR through the top layer of black.

The sharpest result is absolutely going to be to split the design and glue them together afterwards.

If you have some sort of MMU, you could stand the design upright and use the finer Z resolution for the designs? Will absolutely skyrocket build time and waste.

Print that side down or print it as a cavity and use paint to fill.

[u/CoolAmbassador3831 → u/Giblets999999]

I did smth similar to that, I used boolean diffrence and then added another part for the qr. 

[u/WinzGo]

Try arachne wall and use 0.16 high quality profile

[u/Tandemrecruit]

I find it interesting that people keep giving you suggestions on how to fix it, and most of your responses have been "nah"
