3d Printing chair

Grasshopper

Hi! I’m creating a 3D printing visualization for a chair that needs to print bottom-to-top in Grasshopper.

Setup:

  • Hollow chair (lofted walls between two rectangles)
  • Seat with boundary surfaces (5mm thick)
  • Need to show the complete print path from bottom of chair → seat → back → top

Goal:

  • Visualize the print path as a continuous curve that traces bottom-to-top
  • Show layer transitions with a vertical seam along the back edge
  • Clearly indicate the printing sequence and order

Challenges:

  1. How do I create a multi-surface print path that flows in bottom-to-top order?

  2. How do I add a vertical seam curve to mark where the printer steps up between layers?

I’ve got individual surfaces working (bottom, seat, back, top) but struggling to connect them into one coherent visualization that shows the correct print order.

Any suggestions on workflow appreciated!

Can I be cheeky? Just model it as a solid and throw it in a slicer, take your visualizations from there.

With “spiralize” on you won’t even need the layer step seam.

Some like Cura IIRC can even generate an animation of the printhead building the thing up.

Good luck!

What’s wrong with this?
