There’s one that gives you a simple drawing program for making your 2D image, and then produces G-Code so that your 3D printer can extrude the drawing as a single plastic layer.

The Postgraduate in 3D-printing Architecture course at IAAC supports students in creating large-scale architectural prototypes through the use of digital construction techniques.

At this point, you can basically track any G-Code command and also insert arbitrary new G-codes, for example G1 printing moves (for wipe towers) or M280 commands to control a servo.
