Hello, I’m a university student and am in a situation where I have to create the g.code to 3d print my own support structures.
Basically, as the image shows, the first step is to generate a brep under the overhangs and undersides of objects. There have already been point based versions of this, for example here: https://www.grasshopper3d.com/m/discussion?id=2985220%3ATopic%3A887878 where a series of points is projected. However, rather than just a rough series of points, I would like to create precise regions within which I can ‘trim’ my support structure (which will be another problem I’ll eventually have to deal with).
The second stage, if we can work out the first (i’ve tried searching for 3 hours and came up with nothing) is to further divide this region and create a buffer zone between the support and precise printed object (shown in the second part of the illustration).
Thank you so much for your help.
