    I would think that simplify3d's "vase" mode would do what you want but I think it's limited to things that actually look like a vase (eg, thin walls, no infill, no top surface)

    You can make a stab at doing this by hand.

    You would find the first G1 move in your gcode, and make any G0 moves after that point into G1 moves until the end.
    Then, make sure every G1 move has a small, positive E value (like E0.0001). This would have some overfill, but if you're not concerned about that, it might meet your needs.

    This would give continuous extrusion (always flowing), but not at a constant rate.

    I tried the infill patterns available in Slic3r and viewed the resulting gcode at http://gcode.ws (which nicely shows non-printing moves in green). Moves are minimised using the concentric infill pattern, but I don't think you'll completely avoid them. I'd play with the infill settings with one of the prints you're going to make and see how far you can get.

    I'm desperately looking for a slicer that can generate g-code for a continuous extrusion-process, i.e. without interrupting the material throughput. More specifically: an inkjet printer that continuously pumps the (viscous) filament through. Starting/stopping is not an option due to the delay and remaining pressure in the system. Hence, I want to create a moving path with one starting point at the first layer, and one end point at the last layer. I know that, dependent on the geometry, there are potential overlaps. Due to the liquid filament, however, these flaws are (in my case) negligible. Regarding the structure, I'm planning on printing elevated 2D-structures, i.e. 2.5D structures.

    Is there anything available that comes close to my requirements? Any help is greatly appreciated.

    Thanks so much!

    Like others have said this is called "vase" mode in simplify3D, other slicing programs can do it too and they call it other things. I know KISSlicer can do it as well. But you need to know the constraints of that mode. I think for what you want to do you need some interesting code to get it to work. Like doing architectural design work this would come in so handy because the printing of a 2D-2.5D object like that would be so fast.

    hmm, find out what software mcor use.
    Sounds like a similiar process.
    Although that is broken down to a page by page basis - so maybe not.
