Creating support structures for additive manufacturing automatically

Hi everybody,

I have a model in order to print with SLM machine. However, I have some overhangs in model and I couldn’t create proper support structures with 3D-Printing softwares, because the software tried to build support structures from ground base. But, I should only connect pipes with each other from their up- and downsides with a slightly sloping angle. Is there a way to build support structures automatically in grasshopper? or do you have any idea, how I can build support structures for my model fast?
Thank you for your help!
