Support Between Layers

Bambu Lab P1 Series General Discussions

Hi-
Is there anyway to print support filament between layers and not anywhere else?

Thanks!

You will need to provide more information than that.

Ideally, a screenshot to show what and where you are talking about.

draw him where you want… :roll_eyes:

You can try snug support, but if you are trying to stack objects with only support between them you’ll probably need to model the support as a separate object.

Sorry for lack of details. I’ve got a stack of 10 gridfinity bases that I’ve stacked. I want to use support filament between each base so they don’t stick together. There is a 2mm space between each layer for the support filament. I’ll add screen shots to my orginal posts.

Thanks,
Jeff

Thanks Malc,

What I’m trying to do is: https://youtu.be/RYA0xLryF-g?si=S2L4Wbi0FxXdPufd&t=374

Can I assume your issue is as follows?

  • Enable support
  • Support expands outside of the model
  • Support is massive

Please answer the following:

  1. Did YOU design the Gridfinity models you are trying to stack?
  2. What support material are you using?

Hi-
Assumptions correct.

1.No I didn’t design the models
2. bambu support filament for PLA/PETG

I am trying to duplicate what the Youtuber did in his video. After watching the video you sent, I might not have too.

Thanks for your help,

Jeff

One possibility is to get a roll of PVA support filament then use then stretch the object on the Z axis. Then you could user the layer paint tool to paint layers with PVA then after dissolve it in water.

If you designed the models, the support question is easy.

You would create matching layers where the models connect and load them with the panels.

You then select the filament for the panels and the filament for the designed support.

I mocked it up with a model I am playing with.

Each spring is 2mm, there are ten. There are 9 identical shapes between each model of 0.2mm height.

The springs are one model, and the supports are a separate one. I drag both from the file system into the Bambu Studio window and confirm they are the same model.

I then use the objects panel to select the correct filament for the springs and the support filament for the interlaced sections.

Slice and print.

I have the Fusion file, but I can’t attach it.

I’ve attached the .3mf file.

That 3mf has the same problem I described you would end up with.

If you are capable of using Fusion 360, make the slice I explained previously.

You design a slice of 0.2mm tall that matches the dimensions of the very top & bottom surface, no more.

You stack those into the gaps of the models, the cyan in my model and then drag both into the slicer.

Set the model filament as you need and the gap slices as the support.

Now, the only support material is the parts that touch the top and bottom surfaces.

Okay, it makes sense…but can I do it, that is the question!

  1. Go into Fusion, make a “part/object” that is 0.2mm tall that is between the top/bottom of each grid. This will be the support filament layer.
  2. In studio, in object, the grid is PLA/PLA-CF, etc. and the 0.2mm “part” is support filament.

I believe this is what you are suggesting.

Time to dust off the Fusion skills.

Thanks!

I do not use Fusion, but, I suspect it has the ability to select a face and turn into a separate part you can extrude to 0.2mm.

It is worth a try as it would be a shortcut given the base/top surfaces are the exact shape you desire.

This is also a solution, but I am happy to report that draw/paint worked the best and was by far the easiest solution!

Thanks everyone for the help!
