Divide an STL file in two parts? Possible?

Hello,

I have a prusa Mendel with 10cm max height and I need to print a larger object.

Is it possible to divide the part in two parts and bond them afterwards?

Also, is it possible to do it in SolidWorks?

Thank you

NETFABB Basic allows you to cut STL files into multiples.

You can download it from netfabb.com

I have printed sperate parts and merged them. I have used SCAD and generated 2 pieces with registers to line the two pieces up, but I did not start from STL files. I had the original scad files.

I experimented with using super glue, and acetone. Both worked to join the pieces., with the acetone it took longer and wasn't a strong join.

I didn't use the piece in a loaded way, I don't know how well the joins would hold up. I expect the super glue would work until the ABS failed.

Hello, the basic free version doesn't allow to cut the file. Thanks anyway.

if you can post the stl file it should be too hard

Thank you for your answer but I didn't understand what you meant.

Actually, I use the free version to cut STLs all the time

SolidWorks can cut STL's just fine, assuming the STL doesn't have too many errors. Just import it as a solid body (under options in the open windows). You can then cut it and re-export the parts as separate STL's.

Thank you but the latest version 4.9.2 doesn't allow cut on the basic free version. See this comparison between versions: http://www.netfabb.com/comparison.php.

This image I'm uploading shows the version and the options in the PRO.

Can you share your free version installer?

Thank you

v4.9.0 still allows cutting in the Basic (FREE) version.

... cutting AND exporting as separate STL's?

Some of my similar tools are limited only in exporting/saving the results when run in 'free' mode ...

Blender 3d should be able to do this. Just import the .stl remove the vertices below the cut line and then add in a surface to close the solid. Then export as a .stl. Repeat for the other half of the object.

... this wouldn't work properly for meshes cutting the 'cut-line' - try with boolean operations or search a solution, that divides the involved triangles along the cut ...

The CUT function works fine in v4.9.2 - only the Free Cut doesn't work.

To use the Cut function adjust either the X, Y or Z slider in the Cuts group on the right hand side and then click on the "Execute cut" button. Now press the Cut button on the bottom right hand corner. Now at the top right hand side of the window you see Parts. Select the desired part and Export to STL Binary.

Thanks Bob! Saved the day!

Hello, i was trying the split command in netfaab that is disabled.

I finally found the cut method in netfaab and works great.

I also found in youtube how to divide the solid body and it works better than netfaab because it leaves no holes.

Thank you all in this forum that helped me alot!!!

Someone was advertising a new software product being developed that's supposed to go even one step further than simply slicing, by automatically adding post and hole to register the pieces during final assembly.

it's here in the reprap forums somewhere. I'll dig around and see if I can't find it and post the salient link. Even if it's not ready for prime time, it's exactly where I was thinking for larger assemblies and *was thinking about creating some scripts for in Sketchup, but afaik, their solution works at the slicing stage. (disclaimer, I don't work for em, don't know em, and in the end, don't really care. I just think it's neat and has potential for all the slicing solutions).

EDIT: here it is: File2Part

Again, for the record, I know zip about the company or product. It's just a heads up for printers for what's down the pike and for software authors involved with skeinforge/slic3r/etc... This, if it works, will be something awesome for those of us who want to build larger scale "models" without increasing the print bed size...or even then...

erm...Hold on, just went back to their site for the low down. That feature isn't scheduled for inclusion until next year , so software guys...get crackin!
