Extrusion multiplier modifier
Hi there,
I found this thread, but it does not help me..
My model: Think of a cylinder with a thread at the outside (40mm diameter). In the middle of this cylinder I have a bore of 4mm from the bottom to the middle of the cylinder, from than up the bore widens to 20mm diameter (approx.)
I want an overextrusion around these bores, to make them watertight. I dont want overextrusion at the outside of te cylinder to keep the thread alright. Thus, the tip with the mentioned command of the link above does not help me, as my desired modifier is not bound to a specific height. The extrusion should be different in the middle and at the outside (radial change, not vertical).
Is there a way to do this?
Summary in short: How can I add extrusion multiplier modifier?
Best Answer by Neophyl:
Extrusion width is just how wide the lines are printed, thinner means the slicer will have to fill the space with more. It wouldn’t effect if the part was water tight really. Also printing lines thinner than the nozzle diameter doesn’t really work and will in all likelihood make your issue worse.
I thought your stated goal was to over extrude in certain areas to get more filament fusing ?
That is not possible with modifiers in Prusa Slicer but is in Super Slicer as that was added to the available options for the modifiers. If you intend to achieve more fusion of the filament in a different manner then please explain what you intend to do instead and maybe we can suggest ways to do so.
Thinner layer heights should also theoretically produce more fusion to the layer below but as with any of this it will require print and test to determine what will actually work for your application. Personally if I had to make a print water tight I would use a coating to seal the layers, something like xtc-3d for example.
RE: Extrusion multiplier modifier
With Prusa Slicer you cannot. However if you download Super Slicer you can. Super Slicer is a fork of Prusa Slicer that has many many more options to tweak. The current stable release is 2.2.53.3 located here https://github.com/supermerill/SuperSlicer/releases/tag/2.2.53.3
Its built on Prusa Slicer 2.2.0 so should be familiar if you are used to PS. Future versions will be built on the PS 2.3.x versions but wont be released until that is out properly.
One of the modifier options is Extrusion Multiplier.

Alright... Thanks...
Do you think, there is a workaround with the extrusion width? I am not sure, what this parameter really does... I just realize, that I get more "lines" in the slicer, if I reduce the number (from e.g. 0.45mm to 0.3mm) I can do this for infill and see more lines. But I am not sure, if it automatically reduce the material throughput, when doing more lines...
I dont see a difference, when doing this for contours, anyhow..
Is a workaround possible with some of the available parameters?
As said before: The goal is to get more material in the middle, with better adhesien to the layers and neighbour material..

RE: Extrusion multiplier modifier
Thanks again!
That somehow answers everything...
I will try different Things and also superslicer... that one sounds most promissing.
If i dont get there, i will if course also try epoxy... but only if i dont get there with 3d print settings 😉
