Hi, the mesh is infinitely thin, when you say give it thickness, do you mean by creating a 1 mm offset in the fusion stage - ? I did try that at some point but still couldn’t get the ashes to join properly to the “drawn ring” below it- any idea how I make that bit happen thanks for your input by the way

Hi Owen, it appears to be a problem with the upper part of my model which is an open bottomed Mesh as this is where it closes across. the bottom "ring section prints ok on its own, but if I try to print the upper section on its own it fills across the open lower neck so to speak. I thought I had uploaded the fusion file in my post the Experiment1 v1.obj attachment after my 3 images (It is my very first post ever so sorry if I didn't do that correctly ? )

Thanks for your comments, I believe you are correct in that you say the upper "Mesh created part" and the lower Fusion created "Base mounting Ring" as I call it are not fused fully into one object. Hence when slicing cura sees the "Mesh created" upper section of my model as an open ended mesh and closes it across . I have tried so many ways of forcing them to join, combine, etc, including trying to make the lower ring sketches into a mesh and stitching the meshes etc but all without success. What I want is one complete model that is totally hollow , rather like Top Hat from Alice in wonderland if you understand my meaning. Any idea's would be much appreciated. Sammysuj

I am a real beginner, so apologise in advance if I am doing something so totally obviously wrong to you experts out there, but I have been trying for months, with hours and hours a week to solve this issue without any progress,(I hate to add up the wasted time) So pleeeeease please someone out there take pity and help me out. Tell me what I am doing wrong or better still help me fix it. I am using a combination of Autocad 2017, Fusion 360 and Meshmixer. started with an imported scan of a very thin walled hollow object. Drew up a base ring for it to sit on and in inserted into fusion360, modded the ring extruding sections sections to create my required base with fixing lugs etc. The mesh was then "embedded" into the ring. Everything looks fine, when I rotate the object about in all planes I see exactly what I want. perfect -so I thought last Autumn ! when I highlight the entire object and create an stl file for printing -again all seems ok Using Cura 4.4 I can then open the file, land it on the base, again all looks great, even viewing through the build plate from underneath again all looks fine. However as soon as it is sliced (again it performs this perfectly) then when I preview or even create the 3D print it this is where the problem shows up. it fills a 5 layer thick sheet right across the entire open base at the level where the "mesh joins the solid ring into which it is embedded. I have tried, combine in the Mesh tools of fusion360, even converted the Brep to a mesh and then combined, stitched, played around in Meshmixer, just about every conceivable way I can think of, to stop the Cura slicing stage adding this infill layer across the open neck of the mesh where it joins the extruded ring creation. I know I am obviously doing something very wrong at some stage but I cannot find a solution. Can anyone please please tell me how to solve this ? Experiment1 v1.obj
