Very bad surface quality

[SoapStamps4You @viktormolnar1982 Cheshire]

Hi ,

 

Could somebody advise me what happened with the new software regarding flat surface quality? It wasn’t perfect with the settings I used neither using the built in “fine setting”, but now it is terrible. I attach a photo with 2 problems. The top solid infill is not solid but I can clearly see the lines next to each other, it’s very bad.

 

Is it normal that I cannot change the solid infill and top solid infill settings? I use the quickfill head but only the 0.3 nozzle as the other’s result is not a good quality.

 

If someone tries to help, thank you

Viktor

The unfilled lines are due to the narrow lines. This is common with 3D printers and the design should take the nozzle diameter into account. You should make the narrow areas a multiple of the nozzle diameter. You may still get some gaps in the top layer.

The broken infill looks like it is the result of a poorly calibrated print head. What are the X, Y, Z and B values in the table under Head EEPROM in the Preferences menu in AutoMaker?

Hiya mate,

Thank you for helping me.

I made a screenshot of the Head EEPROM settings. I am running the calibration now.

@viktormolnar1982 has the calibration resolved the problem?

Hi Pete,

 

Thanks for asking, it is a bit better, but still not the best, in some cases I see gaps, but no more significant. However the issue with the various line thickness is still there

You should make the narrow areas a multiple of the nozzle diameter. You may still get some gaps in the top layer. -> please clarify this from BHudson. So I have the nozzle at 0.3mm but in the fine settings the perimeter extrusion with is set to 0.35

That’s fine, but I have continuous lines with different thickness.

Please see the picture and see the symmetric holes on the sides of the heart.

Regards,

Viktor

@viktormolnar1982 I don’t see anything wrong with the picture you showed of the heart. That looks about like what I would expect from an FDM 3D printer.

Ok, in this case I accept the answer, but this quality is not good. Let’s sort it in a different way.

 

Do you recommend or use any plastic filler pasta that can be sanded by sandpaper afterward to fill these tiny little holes?

 

Thank you

Viktor

@viktormolnar1982 I think that your expectation may not be realistic.

There are several modeling compounds used for plastic models that I would recommend as filler. You can also try car body dent filler.

There are limitations to drawing shapes in the XY plane which are mainly the nozzle diameter.

If you imagine drawing a shape with a 0.3mm pen and can only create this size line with no overlaps or partial lines then you can see where the gaps will appear. If the 0.3mm line cannot fit in a space then the space is left empty.

If you were able to turn your model so details are created by putting layers on top of each other (in the Z direction) then you will be able to achieve far finer details.

We printed these on their side, you can see in the images at the bottom how they were printed, the text detail is very good.

Hi

Sorry don’t agree its the splicer I have printed the same model upside down as you get the best surface on top - the splicer is the let down the sooner this is improved the better I am using version 3 and can’t see any improvements over v2.0 or 2.1. square cut outs are sometimes square and other times nearly triangular - print the same model on its side and you get a different set of problems.
