Minimum Extrusion Distance
Is there a setting to disable very small extrusion lengths, like a "Minimum Extrusion Distance"?
Several prints automatically generate crazy small extrusions, a very small dot of material in the corners of some prints.
This is quite literally adding hours to prints where 50-100 of these parts are printed in a batch.
The white extrusions are the ones in question:
RE: Minimum Extrusion Distance
The white is called gapfill. You can turn gapfill off completely by setting it to zero but you cant as yet control the minimum length. The danger of turning it off is that depending on the model you could get voids in the walls.
There’s a GitHub issue requesting a minimum a length like you want but it’s not available in PS as yet.
There is also a fork of PS though called Super Slicer that has had this implemented for awhile though. The stable release of Super Slicer is still based on PS 2.2 but the developer is currently porting 2.3 but it’s a bit unstable and has issues at the moment.
RE: Minimum Extrusion Distance
Sometimes I can make the gap fill lines go away by getting them to be part of a perimeter. Your print is going to be challenged because you're square outside and round inside - if you change the shape to have a smooth perimeter, and then fiddle with extrusion width (yep, you can adjust that), you can probably get rid of all of any gap fill. The slicer will try and fit internal or external perimeters, or use fill.
RE: Minimum Extrusion Distance
Thank you very much, for the help, I am currently trying both of these solutions and testing the parts. I think the part will still function without the Gap Fill. Very interesting, I did not realize that was its own element in slic3r.
I've increased the number of perimeters to 5, which blends the interior and exterior walls together, eliminating the Gap Fill. I'll see which solution works best!
RE: Minimum Extrusion Distance
It would be helpful if you would save your current 3MF project file, zip it up, and attach it to a reply here so we can see your part & settings and give better recommendations.
RE: Minimum Extrusion Distance
It would also be helpful to know, are you looking to only have a clean top layer, or are you wanting to change this throughout the model different solutions can present themselves, what Bobstro mentioned is impotent since the particulars of each model are different, and different solutions present themselves for different needs. I want to add that the .3mf should be zipped up with winzip, 7zip, or winrar <--(in zip format) and posted via the "Add Media" atop the area where you type your thread, you can drag and drop it into the resulting window.
Enjoy
