Poor print quality in fine lines of model

I am having poor print quality of the lines in my model after printing as you can see in the lines. The lines on the front side have the poor print quality but the backside (which is the same design without windows, door and sign), those line are printing clean.

The lines are .3mm and I am using a .2mm nozzle. I am using Arachne wall generator and the 0.06mm layer height “Fine” printer setting. Thank you!

We would need to see the model 3mf and ideally screenshots of the prepare tab with the sliced model using the line type view.

As uploaded 3mf files are not working currently, you will need a web service like WeTransfer and then paste the link back here.

Use any service that lets you paste a URL and is free to you and those downloading.

My first guess would have been enable Arachne, but you you have and you are using a 0.2mm nozzle, these are both ways to get the best detail.

Thus, the need for the model file. If you didn’t design it, share the link for the model instead.

I designed the model. For now I will upload the file here since it seems to be letting me. Ill work on getting the screen shots.

As I said, the 3MF files cannot be accessed; you may be able to upload them, but we cannot download them!

Your screenshot matches your printed models.

As well as a link to your 3MF from a different service, please also share the screenshot from the Prepare Tab.

Update ^^^^^

I should have said Preview, that was me.

That was a screenshot from the preview tab.

Can you clarify what is missing? Your STL image, your print preview, and your printed product all look consistent to me.

That is exactly what I am getting from your 3mf.

Your printed model, preview and sliced information are all the same.

Your description suggests you expect one to fit into the other, but your model doesn’t have that appearance.

This isn’t a slicing issue. It is a design issue.

Did you design this or is it from a different designer?

If you look closely the lines in the model on the left (front of the house) are not smooth compared to the lines in the model on the right. I guess it might not be missing parts per say but it’s definitely crummy printing.

Looks like a cooling issue to me.
Also, because of the windows, door & sign, you have more seams…stop & go.

I designed it. It’s not meant to fit into each other. It’s a clay cutter/stamp. Those imperfections are what I am trying to troubleshoot. I see that my sliced file is fine Im just wondering what I can do to get a cleaner print?

Finally I think I know what you are talking about.

You are concerned by the quality of the part with the windows and door.

Is this correct?

Yes that’s correct, I guess missing parts was misleading but to me it looks like there are gaps

Ok thank you. What would you suggest as a fix if I must have the seams?

I am doing a test print.

Poor print quality on the bars on the left model.

When you say there are missing parts, it implies that things you expected to be printed were not. Especially when you stated you used Arachne, which is designed to provide extra details that can be missed without it.

Do not worry, we got there.

I did a test using a 0.4mm nozzle and a layer height of 0.2mm.

It turned out almost perfectly, but the right side of the left window isn’t perfect.

I suspect slowing it down would have rectified that.

Questions:

  1. Why are you using a 0.2mm nozzle and a layer height of 0.08mm?

  2. Your 3MF wasn’t recognised as a valid 3MF. What version of Bambu Studio are you using?

Hmm. I’m using a layer height of 0.06mm as it was a “fine” preset and I thought that would be best for achieving the finest lines/details. The version of Bambu Studio I’m using is 2.0.3.54. Also, I created the 3mf using my design program, Shapr3d. Im new to all of this so I don’t know what I’m doing really, and please direct me if you can.

Fixed! For those who come across this problem in the future. I messed around with some settings and now it’s printing clean :grin: I noticed the poor quality was a result of sparse infill in the walls of the print.


I unchecked Arachne and checked “Detect Thin Walls” as well as increased sparse infill density from 15% to 20% with a Rectilinear pattern. Also changed the internal solid infill pattern to Monotonic.

When sharing 3MF files, you do this from the slicer, not your CAD software.

You applied settings in Bambu Studio that you didn’t share because you didn’t provide the correct file.

This made it impossible to review what you did (as I mentioned previously) and also meant my first attempt was nearly perfect using a thicker nozzle and thicker layer heights.

Something to remember next time.

BTW, I did none of those things and it worked fine.

I only enabled Arachne, and all other settings remained as their defaults.
