Brim only for some objects on the build plate  

RE: Brim only for some objects on the build plate

Unfortunately, it hasn't been implemented. It has been requested but there is no telling how far down on the list it is for the programmers.

RE: Brim only for some objects on the build plate

So we will get this functionality - it´s just a question of time.

Thansk, best regards,

RE: Brim only for some objects on the build plate

Hopefully it will come. Until then, one is left performing two print jobs. One with brims and the parts that require them, and one without brims for the parts where brims will be problematic. The parts that are brim agnostic can be allocated to either.

RE: Brim only for some objects on the build plate

Alternatively you can manually add brim like features using modifiers.  Basically put a 1 layer high modifier under your part to act as a brim.  Can be used to do brims for just parts of models too like in the corners.  I use the technique all the time where needed.

RE: Brim only for some objects on the build plate

The same way I do - it´s a work arround and could be solved in the future more comftable. Thanks, Clemens

You can create "pseudo brims" is you just need to hold down a few parts in a few specific spots. There was a discussion on using part modifiers to create "dimes" or "mouse ears" in problematic corners.

It's not as graceful a solution, but it does work for now.

I'd really like this feature too

RE: Brim only for some objects on the build plate

Hey @bobstro could you please share your settings for those circles at the corners? 

I've checked the modifiers part but couldn't find this. My large prints are warping in PLA (even in an enclosure) and I'd like to avoid a brim on the whole component.

Thanks

Here's the original discussion. I tried 2 different techniques:

• Resizing an actual disc-shaped part to fit in corners, specify 0 top and bottom layers.
• Use a part modifier to create a disc in corners.

Both approaches worked. Note that the appearance of perimeters lines will be different on the bottom layer, either showing the outline of the disc in the corners, or hiding the perimeter lines. Depending on how much squish you've got on your 1st layer, this may nor may not be noticeable. With a textured sheet, it shouldn't be visible at all.

Awesome, thanks a lot for the quick answer. 🙂

I would think that would be a no brainer to have the option to add a brim to some objects and not others on a build plate.  They have all the other options in the right drop down list so why on earth did they not add the brim option with all the others?  Why they left just that option out and have all the others I don't know.  But I sure hope they add it!  I just wasted a lot of material on a brim on an object that didn't need one.

RE: Brim only for some objects on the build plate

I would also like it if they added this feature.

RE: Brim only for some objects on the build plate

Been a couple years... devs, any chance this is coming any time soon?  Is there a more appropriate place to post this feature request?

The place most likely to get any attention from the actual developers is over on the Prusa GitHub pages. You can submit a feature request, or add a "me too" to existing requests. It looks like there's at least one open issue.

@bobstro

Thanks!  I added a comment there as well.  Appreciated....

RE: Brim only for some objects on the build plate

Bumping this request for the top.  Would be nice when nesting multiple models to Brim select objects.

RE: Brim only for some objects on the build plate

Please realise that the forum doesn't drive development requests.  There no point in 'bumping to the top'.

If you read the thread it has been pointed out that the correct place to make requests and add support to existing ones is the Prusa Slicer github.  Bob even has a link to one a few posts up.

If you arent familiar with it the github for slicer is located here https://github.com/prusa3d/PrusaSlicer/issues

RE: Brim only for some objects on the build plate

This is already available in 2.4.0. Right click object > Add settings > Skirt and brim. You need to be in 'Expert' mode.
