I'm trying to make a tubulanes infill but I'm not exactly sure how to get from a model file such as a .stl or .obj to a .wkt file so I can create a new infill design for more structural durability anyone have a how to on how i can get from point a to b so I can get my custom infill?

    You can only do it with 2D shapes, not 3D models. Here's the format, a program like Inkscape might be able to convert a vector drawing to it, I haven't tried.

    Is there a way I could slice the tubulanes into 2d slices and have Cura interchange the infill patterns to build the infills into the intended shapes of the tubulanes?

    Kinda like how a block of cheese can be sliced and when stacked up still retains its original shape?

    Sorry, I'm pretty sure that's not possible, has to be the same thing repeated on every layer.

     

    There are completely impractical (I mention them only because they're technically possible) ways of doing it: have two different infill patterns (one for each direction) and then for the layers where you want to swap, make a support blocker and turn it into a modifier which changes the infill pattern. A post-processing script could rotate the infill every few layers but unless your model is a square, you find me a coder willing to take that on and I'll buy them a drink. A plugin (which is more complicated to make than a post-processing script) could do it more easily (well, less difficultly) than a post-processor but it'd still be a pain to make, not to mention all the boilerplate stuff involved in a plugin which isn't needed for a post-processing script.

    so, there isn't a way to slice it into separate infills and then have it interchange the infills each layer, that sucks, maybe a coder will come along and figure out a solution, I only do 3d modeling as a hobby and I barely know anything about coding, it's just a tad dry of a subject for me to get into. If you figure out anything hit me up, would love to find a way to make this super strong infill into an everyday tool at some point.

    You can submit your idea at the feature request page. Although a lot of the types of infill in Cura are already pretty strong if you print them at a high density, maybe they'll like yours.

    Hi, where do I add the new wkt file to. As in, where in the file structure is it located?

    On my Windows computer they go in:

    "C:\Users\_my name was here_\AppData\Roaming\cura\5.8\plugins\CuraEngineTiledInfill\CuraEngineTiledInfill\tiles"

     

    On most models the walls provide 90% of the strength.  If you require strength from the infill then this will do it.

    5 walls, Grid infill at 7% density, "Infill Wall Multiplier" at 5, and Infill Line Directions are [0].  You can park your car on this no matter how you set the model on the floor.  No single line infill can come close.  Any "curvy" infill is either directionally handicapped, or is only good for holding up the roof.

    This is my own "Double Sine Wave" infill.  It has some strength in the Z but it's an accordion in the X and Y.  Gcode files are almost triple the size if I use this.  It was a sort-of-interesting-for-a-minute exercise.
