Printing Marvin with non planar tool path.
Using Curvislicer with Gurobi it took me 1h40 to generate the tool path (the G-code), and 29min to print using 0.8 nozzle.
3D Marvin is just a demonstration of the technology.
Let me know if you want me to make a detailed video about Curvislicer and share with you my experience with it.
