How to Print Without Walls

[wcrisman]

Is there a way to take a model and print it without any exterior or interior walls? In other words, print only the infill.

The way Simplify3D sets up the printer to print the infill would be great for creating a media to house bacteria where water can freely flow through the object and the bacteria has a lot of places to grab on. Creating such a design in a traditional 3d program such as SolidWorks is quite difficult since we really want the resulting print to have the thinnest possible structure, similar to what is created by Simplify3D for the infill at a low percentage (say 10%).

You could try going to the Layer tab and setting the top and bottom solid layers to 0 (this will remove all roofs and floors), then set the number of perimeter outlines to 0 as well (this will remove the sidewalls).

Just did a quick test and it worked for me
