SuperSlicer Tree supports

Tree supports

Just tree supports as cura or meshmixer has, they are already there for the SL1, so why not for FDM

this would be amazing to have - but idk if it will ever come? Adding tree supports seems like a very hard thing to do

prusa is working on that (for the sl1 support). So it should come in some weeks or months.

for just SL1 or for FDM too?

Yes, because the functionality is already there for the SL1, just not for the FDM

I'd definitely like to see this.

I just read this and now I covet them too.

For what i understand, you can see that the cura tree have thick branches and the current prusa sla one are thin, so it needs significant rewrite to make them suitable to fff.

I hate Cura for its UI and overall its bulky. Right now I'm having zits on my prints, that do not present on any other slicer. But I love tree supports, that only Cura offers. Much less print time, easier to remove. Sad, that it's hard to implement.

No need for significant rewrites, it's fine as it is! When I was young I'd use to print 3D scans of people on commission and used Meshmixer SLA supports extensively for my FDM prints. I'd just dimension them to 3mm diameter and a 1mm tip. No auto-generation either: the trick is to identify the spot where extrusion in the air happens first and add a support to that.

Currently I do the same with SuperSlicer: I have a SL1 profile, import my STL and manually add supports to that. Then export the STL including supports, open in FDM profile and scale up to achieve ~3mm diameter supports. Similar to this

edit: changes I'd like to see though:

ability to change support diameter and tip diameter
show overhang area's while adding manual support
add support from point to point, so I can add support from one point of the print to another without having to originate from the base plate (potentially save a lot of material)

i can't for the life of me figure out how to get one of those. in the "add/remove printers" dialog, all i get offered are various FDM ones.

given you said that 2 years ago, do you have any more insight on their progress by now? kinda looks like they're not doing much for that feature :/

They tested it for fff but the result was worst than the actual support stuff. The PS 2.4 has some improvements. For tree support... maybe after.

Happy New Year! Now that PrusaSlicer 2.4 has been released and will be merged in the next version of SuperSlicer, where do we stand on this essential feature of tree supports? For my high detail model prints, tree supports is an invaluable feature. Adding tree supports is the difference between me using SuperSlicer exclusively for all my prints and me today still having to use Cura to avoid otherwise failed prints with my highly complex models.
