Faulty STL file? - solved

[3d-magic 0]

Hi everybody,

I'm trying to print a cilinder on which a dragon is projected. Somehow, I am facing the same problem over and over again.

When the printer starts to print the part where the dragon is located, the printer seems to skip layers of the cilinder itself. No matter which settings, temperature, speed etc. Everytime it starts to skip at exactly the same height.

I've tried to recreate the stl, but still the same effect.

When I look at the file in Cura, I notice that there are some irregularities there. But when checking in my 3D program (Cinema4D), all seems OK.

Can somebody please check my file to tell me where it is going wrong?

Regards,

Richard

That website purposely slows down the download so it will take a few minutes. But the first thing you should know is never print anything before checking it carefully in cura layer view. There's no need to waste time printing errors when you can see the errors just fine in Cura layer view. You have to wait for it to completely load before checking each layer. You can use shift key and up/down arrows to move one layer at a time. Go up and down quickly looking at different areas of your part each time.

The next thing you should know is to always look at your part in cura xray view. Any red areas are potential problem areas. You can often fix them by going into expert settings and there are 11 combinations of checkboxes in the "fix horrible" section.

Up it just downloaded. If you check every box except for "B" in the fix horrible settings it looks okay - I only did a quick look.

I opened it in Netfabb and it seems to be an invalid mesh. Tried to repair it but it's still invalid...

Well I hate it when people make me repeat myself:

If you really must fix the STL then this procedure might work (although it might leave you with holes in the print). I suspect it will work for you although you might need to drastically increase the light source:

 

removing internal nodes/faces

But really - just check the 4 "fix horrible" settings (except for "B") as that will only take a few seconds versus an hour installing and playing with meshlab.

Didier is not the thread starter. He was simply trying to help by checking the model in Netfabb which shows the model itself is to blame.

Yes indeed :mrgreen: just trying to point out that the file is probably shitty for some reason

Thank you all for the advice. I'll try a new print today with the proposed 'fix horrible' settings.

Yes! Thank you gr5, your advice helped. :smile: This time the print was okay...
