Details lost during slicing

Hi everyone,

Pretty new to the Bambu Studio and would need your help.

We’ve created a model in Fusion360 that is a stamp with some text.
When importing the model, the text is shown correctly but after slicing it, we lose half of the text.

But after the slicing, text is lost

I tried to play with the quality parameters and speed but no luck.

Any advice or good tips?

Your nozzle can only lay down lines roughly as thick as the nozzle diameter. Anything smaller is normally not possible.

So you could switch to a smaller nozzle like the 0,2mm one and slice it again to see how that would come out but I am afraid, FDM is just not the right prozess for such details.

What you could try is to change from ‘classic’ mode to ‘arachne’ - arachne is a bit more flexibel in case finer details are required.

Hi Christian,

Thank you for your reply.

While it makes sense if the details would be really too small, in this case, I was able to slice it correctly with CURA and print it on an old ProFab (Monoprice MP mini) with a 0.4mm nozzle.

So it seems more likely to come from some parameters that I don’t grasp yet or a slicer algorithm that drops some vertex.

Did you figure this out? My Prusa M3S with .4mm nozzle can print fine detail text. If I select my Prusa in Bambu Lab Studio and slice my model, the text shows with all the detail. If I select my Bambu Lab P1S and slice, the text loses most of the detail. In other words, I can see the loss of detail by looking at the sliced model in Studio. It must be a printer configuration setting or simply some hard-coded limitation in the P1S printer settings.

Hello,

I would like to re-activate this subject. I have exactly the same issue as the one described by mx1m3, with Bambulab Studio configured for an X1C.

And as mx1m3, no problem with Cura and my old Tizyx printer.

Could anyone figure it out ?

Have you checked the font? I have some models that look great in one slicer and look terrible in the other. Turns out there are errors i.e. broken manifold surfaces in the models that some slicers don’t show. Some printers can sort of cover it up but the parts tend to be weak in those areas. It seems to be on the top and bottom that you have the most missing data.

Also just for a test try making the font bigger, sometime even a little larger fixes things.

Try slicing in a different program and then re-import into bambu labs. Many times I’ve fixed errors that way

I can confirm the the Bambu slicer struggles with certain fine details, not just text.
This even happens for models where the to be sliced areas are clearly wider than the nozzle diameter.
The issue is more dominant with STL files and a bit less with STEP files.

While changing to Arachne can fix certain things it still fail in many cases.
For some strange reason DECREASING the accuracy in the advance tap often allows for those models to slice just fine.
Like by changing the default resolution from 0.012 to 0.5 or 0.1.

It certainly is a firmware/machine setting issue.
The Bambu slicer simply fails to convert to model correctly into layers for processing, resulting in lost layers or empty layer sections.
What stuns me is that quite often just a slight rotation of the model around the Z-axis makes it slice just fine…
Or at least makes different areas fail…

Hello,

I was trying to print a part where the text was added with the CAD software

I retried today with adding the text at the slicer level, and it worked well. But it may also be the result of upgrading the slicer to version 1.9

Anyway, thanks for your answers.

i been having the same problem all nite. 3 prints and about 20 blender files as tests.

what i found is u need to add more vectors i think i used .decimate


but it slicing is working now.

also non-manifold eges tut helps

Solved it for me. don’t know why but it worked

2 posts were split to a new topic: How to get straight seams?

Very strange, i have the same thing here. Just happend all of a sudden today. Not sure why. First prints where good. Now it just doesnt will the text at all…

When u add text, click on text a then split text to parts so every letter will be object for itself. It worked for me.

interesting. I wish Bambulab would give you a warning when it can’t print the fine detail in text.

To be fair, the Slicer can’t tell you everything it can’t print as much of the entire model surface suffers from loss, simply due to layers being thicker than the triangles it is presented with to slice.

It would need to show you thousands of locations.

The various views in the preview mode give you the ability the determine what does and doesn’t work as expected. Also, using the layer bar helps you know what will and won’t print internally.

Often I forgot to check that an embedded magnet space exists, simply because I forgot to check.

Text is prone to issues and should always be checked. The nature of text means it often has thin walls. You can often get a better end result by using the Arachne mode for wall generation.

But, checking twice, printing once is a great rule of thumb. One I need to remember.

I also had this issue with text.
What fixed it for me was to, in addition to switching to Arachne, reduce the Minimum feature size in the Wall generator settings.
