I am new to FDM RP. I've done a lot of work on ZCorp and Connex.
The question is can vectors curve drive an extrusion nozzle? Within a 3D volume I can generate curves that I want the print nozzle to follow. Is this possible or has it been done? If so, what software or is there a hack?
Another question is, can you print a part with no sidewall or containment boundary?
