I have a hollow object with 1.7mm wall strength.
There’s 1.3mm deep patterns indented in those walls, meaning that the walls inside the indented bits are just 0.4mm thick, which leads to holes around those places when doing a 3D print.
Any suggestions what I could do to correct this situation? I would only universally increase the wall thickness as a last resort.
This might be a bit Off Topic as this is going to be a 3D Printer issue.
What printer do you have?
What is the minimum wall thickness you can live with? 0.8mm? (2 perimeters worth)
And, do you want to maintain the overall 1.7mm hollow object wall thickness?
If so, then reduce the indented pattern depths to 0.9mm.
Is this the correction you’re looking for?
Agreed, it’s a borderline 3D printing/software issue.
If Shapr3D supported a “displacement” function, where the pattern I push through one side pushes the wall out oh the other side, it would be easy.
But now I seem to have met a limitation of the software. I’m working on a reproduction of a classic game case made from plastic, so the wall thickness and the indentation depth is a given.
I understand. You can do a ‘displacement’ maneuver so to speak. Eliminate the hollow by filling in the center then use Shell at the wall thickness of your choosing. First, I would make a duplicate of your original then try the Shell. I say this because there may be features in the indented patterns that might constrain the shelling.
Maybe I’m not understanding your actual problem, but you should be able to print a wall thickness of .4mm with a .4mm nozzle.
