Topic: Fixing STL's

I have an STL file of a part I want to pint and its throwing an error.

In a previous thread, it was mentioned that certain slicers have repair features.

Slic3r no longer runs, despite installing it again three times, just does not run.

I have been on the Linux forum I got the distro off and I am getting the usual BS that you get in such forums, infact the responses are very much like when I use Ubuntu and MINT. Generally you get the pointy finger pointing at you claiming you did something or are using unauthorised repositories or installs not compatible with Debian distros and so on... Usual sort of rubbish to cover up the fact that their DEV's cocked up and broke the distro.

Anyway, I watched two videos on repairing STL files and I am still none the wiser as in both cases, still showed errors.

The first video was very hard to follow because the guy wasn't speaking clearly in English, seemed to be more aimed at people knowing what he was doing... Neither options yielded a result.

Finally... I see no repair tools in Cura, Repetier, Pronterface, Printrun or the other slicer tool I have. If one of these has an auto fix, it clearly isn't working.

I have tried looking in FreeCAD to see what it could do, despite running repairs, one repair actually breaks the print again and again. as you can see from the image, there are still areas of problem with the file.

Use Nettfab. It's free and it is what most of us use. Simplify3D had autorepair features but it is not free nor do they work well. It looks to me you probably have part of the model not connected with the rest. it only takes a very small gap or hole to freak a slicer out.

Printing since 2009 and still love it!

Re: Fixing STL's

That didn't fix it either.

I found a Linux installer and it still shows the same problems as before, its see the errors but it is not repairing them.

Re: Fixing STL's

When it comes to saving the file, it states that it saved the file but the repair wasn't saved or something to that effect.

Re: Fixing STL's

Well that was painful... After some nail pulling and hair wrenching, I managed to get the part "Fixed" and  "exported in STL format"

so NOW... its PRint time to see if this part turns out the same...

I have used this website to good effect in the past, they allow 3 free repairs a month.

Re: Fixing STL's

Well this is odd...

The one that got "Fixed" now has surface artifacts that were not there with the one that was moaning about not being a cam shaft or an exhaust or something mechanical...

Anyway, anotht piece of information to add to the growing collection.
