Print 3d - error

Has anyone already printed in 3D from Grasshopper and Rhino? did u have to do something different (type delete vertices)? … i just try but giving problem

I’ve 3D printed more than 100 models made by Grasshopper & Rhino. There are some quirks with the process that have to be accounted for, but in general the results are quite good. It is not unusual to have to make geometry adjustments in order to deal with the nature of STL files (you need to learn about naked edges and avoid them), but overall I’ve not found any other software that provides the flexibility of GH/Rhino.
