I hope you are doing well. I’m new to Grasshopper and I want to make a 3D lamp and make it seamless. I want to make my wall in the same line but I don’t know how to do it (I know you don’t understand what I’m talking about, sorry for my bad English but I think the pictures will describe it well)
You did not say what kind of printer you plan on using, but if it is a standard FDM printer driven by a standard slicer program you are not going to be able to do what you want. There are two fundamental reasons for this:
1, Your lattice design has disconnected parts:
Spiral Vase mode prints a single, continuous, line of material around a solid 3D shape that itself has no thickness. It cannot print a discontinuous line of material.
What you can do is print your lattice pattern on top of your solid interior shape like this:
To do this I reduced the number of curves to 10, used them as inputs to the Pipe component, and then joined them with your original sphere-like shape. This was easy to do and will work - sort of.
“Sort of” means the final result contains 160 closed Brep pipes and one untrimmed surface, which is your sphere-like shape. It is untrimmed because it has no thickness, and this, in turn, will cause a slicer program to reject the result due to STL errors. There are various ways to fix these; most modern slicers will do it themselves.
Here’s an example of this technique I made back in 2016: Nightlight4
