![]() In solidworks, you can use the shell command for this. Hollow out your part and set your wall thickness to the desired dimension. I have two methods for doing this as follows (I use Solidworks, but the features exist with most CAD software) Method 1 Step 1ĭesign the part for the geometry that you'd like as you usually would. (Note I use these two methods to design parts for strength, but it's basically the same thing that you're looking at doing) If you want to have a specific infill density, you can design the infill yourself as part of the solid model. Is there an smarter solution to achieve a hollow piece with support structure? This sounds feasible to me, but is quiet a certain effort. I would have to make my part hollow by subtracting a shrunk version of the model and fill it with the honeycomb structure. Searching for an other solution, I found this article, FreeCAD: Perforated Sheets and Hone圜omb, describing how to create a honeycomb structure by a little piece of code. Hence, this way does not work in my situation. Obviously without creating support structures in solid parts. But as I want to print with shapeways, I just know the material, and they are doing the slicing. ![]() If you know which exact printer model is doing the print, Slic3r can do the job. ![]() Googling around, gave me the solution to make it hollow and use a support structure. After uploading it to shapeways, it turned out to be too expensive to be printed like that. I have constructed a 3D model with some bigger solid parts with FreeCAD. This is my second 3D model, be forgiving.
