Simplify3D User Forum

Hi there!

Currently new to simplify 3D. I have done several prints so far and currently loving it. However this one print is quite getting on my nerve.

I'm trying to print a ducted fan for my project. However, when it comes to slicing the object, the software decides to fill in the entire duct rather than printing the duct "correctly". Can anyone identify whats going on? I tried everything such as changing the nozzle diameter, etc. Currently using sketch-up to do my CAD and I have a Flashforge Creator Pro.

Can you attach your factory file? That would make it much easier to give suggestions...

Factory file as in the original .STL?

Try different extrusion widths and see if it slices better. Extrusion width should be an integer multiple of thin walls whenever possible. If your width is greater than the thickness of a thin wall, the slicer will not print the wall.

Also vary the layer height. e.g. if you are using .2 try .19

I'm not sure what your pictures are showing, but in my experience when the slicer fills in open areas of a model it's usually because there are errors in the mesh. Try running the model through netfabb (https://netfabb.azurewebsites.net/) and I bet it clears up the problem.

Tried Netfabb, made the slicing worst.

Any other suggestions? I'm still trying to play around with the extrusion width, etc.

Your shape definitely has issues that cause the one-layer thick web to be added by the slicer. Running the shape through the repair service does resolve these issues and when I load the shape into S3D, with a nozzle diameter of 0.4 mm and a layer thickness of 0.3 mm, the shape slices correctly.

If you have repaired the shape and are having further issues, then please do as has been requested and attach the factory file for this shape loaded in S3D. The factory file is created from the File dropdown menu....Save Factory file as> The resultant file will have a .factory suffix.

Note: I have noticed that you may have a problem with thin walls in the hollow support web in the venturi chamber.

Are you sure it worked? Didn't for me.

But anyways here's the factory file.

If I slice from the factory file you supplied there are single layer webs all over the place. If I then remove the shape and replace it with the repaired shape, the web has gone...but there are spurious filaments going in strange directions. If I then re-configure my S3D for the 5th gen printer and use a fresh default profile, the shape then slices correctly. I have to conclude that there's something not quite right with your print profile.

So....here's what I think you'll have to do...

Run the shape through the online repair service and then use or reload the default profile for the Makerbot 5th gen printer.

I haven't looked at the differences between your profile and the default for your machine....so it may be worth seeing what the differences are.
