I have been working on a 3d printer for the last year.
Its called the Peachy Printer and it will be run entirely by a blender add on.
here is a link with more info

Just wanted to reach out and see if anyone from the blender community has opinions
on this, or if anyone wants to join James Cooper( Head of Programming at Peachy)
in creating this add on.
Thanks
