Create Lines for 3D printing

[Ralle]

Hello,

is there a way to create this hatching (blue) in Grasshopper? However, the hatching should be output as a line, which should have 1mm distance to the red lines and 2mm distance to each other.
The whole thing is to be used as a path for a 3D printer, which unfortunately cannot be operated with a normal slicer.

Thanks in advance,
Ralle

Hello
Nautilus plugin can do it

First journey in 3D printing

Some weeks ago I began my journey in the 3d printing world. The main job was to generate 3d printer paths from closed curves which represent the intersection between a slice (plane or not) and a solid. The paths must be a single curve, which means the extruder never stop to extrude during the print. The results are very similar from what is presented here and on this paper “Connected Fermat Spirals for Layered Fabrication” The main tool is Offset from Clipper but there are many optimizatio…

Hi thanks again for the help, your plugin has worked really well so far. I work at the university with a clay 3D printer. In the last correction I was told that I should use the offset infill instead of the lines infill. However, the offset infill doesn’t really work for me. Do you have any ideas as to why this might be and how to fix it?

This is the first time I’ve worked with Grasshopper at university, so I’m not particularly experienced.
So I apologize for any stupid questions.

Greetings Ralle

Hello
yes it doesn’t work on purpose. There must be a warning on components ? Components with a yellow square needs a licence. Go on food4rhino nautilus and look at the instruction. I could send you an evaluation licence for 15 days.
here the results, better looking with slight decrease of tolerance (don’t go too low it is too slow)

Or some smoothing coud be done with Line And Arcs tools

And if there is some self intersection , you can use

And I will be happy to see the results.
