G-code design in parts by slic3r

3D Printer Slicers

Hi all I have the following question about G-code design by slic3r when having at least two parts in the printing model.

Like shown in the picture below, I have two parts in the printing model, in which the ‘vascular’ part is assigned to extruder 1 and ‘parenchymal’ part is assigned to extruder 3.

Now I want to further explore the following options for generating the G-code;

  1. Extruder 1 (E1) and extruder 3(E3) using two different infill pattern, and potentially different infill density? Can this be achieved? If so, how to achieve?
  2. Always start the extruder 3 first, followed by extruder 1 when printing each layer. So far the autogenerated code goes to extruder 1 first, followed by extruder 3, then following next layer is extruder 3, followed by extruder 1 (to minimize the extruder exchange).
    Essentially the autogenerated code goes
    E1 (layer 1) - E3 (layer 1) - E3 (layer 2) - E1 (layer 2) - E1 (layer 3) - E3 (layer 3) - E3 (layer 4) - …
    What I wanted
    E3 (layer 1) - E1 (layer 1) - E3 (layer 2) - E1 (layer 2) - E3 (layer 3) - E1 (layer 3) - E3 (layer 4) - …

Thank you so much for the help in advance!!

HI @Tg37

Welcome to the forum, Glad to see you here. I like the question you are posing here.

I have noticed that on my slices that they do slice the way you have described. I cannot think of a way you would be able to modify it to see the output you are looking for.

If its possible someone here would have seen it I am sure.

Hi Jason. Thank you very much for helping me up this post. I appreciate. Currently I still could not find the solution and generally I am doing everything manual. This means to generate the G-code by Slic3r first and subsequently, edit the code by myself, which could be extremely tedious and labor-intensive. :smiling_face_with_tear:

In case someone find this could be achieved by other slicing software, please feel free to suggest. I am pretty used to Slic3r indeed but I am happy to learn new software too. Thank you so much in advance.
