I was cruising along with my 3d drawing/printing, thinking I finally had it under control when I ran into a problem with what seemed like a simple project. I'm trying to make an object in the form of a hollowed out shell to go over an opening to provide a "bump out" for clearance (drawing attached). Using TC 2018 and Cura 14.07 with my Anet A8.
The Cura X-Ray view tells me I have some problems with the drawing, which I think I can fix by providing more overlap with the adjoining parts. However, the big problem I have is that I cannot get the object to print with a hollow interior. I've tried printing just the shell of the object in solid form, hollowed out (Boolean Subtracted the interior) and tried printing and tried printing the hollowed out version with a variety of Cura settings. No matter what, my printer insists on filling in the interior - not with support structure, but with infill.
What's the trick to printing the equivalent of an "upside down cup" so that the inside is hollow (after removal of support).
Is it better to use TC to hollow out the object before making the STL version, or, better (feasible?) to make the STL of the object as a solid and somehow (
) use the Cura settings to only print the shell.
I've been printing this with the flange section flat on the bed, thus the "inverted cup" analogy. I'm assuming the flange section complicates this because I've had a lot of prints where the flange prints detached from the main body of the object.
