Solder has weirder melting properties than thermoplastics. Thermoplastics have this very friendly curve where they're melty and sticky. Solder instead is just sort of runny or not, and so it will leak out of the nozzle too thickly, and bead up on the surfaces it touches. This is from what I've read.
That said, people sometimes mod these to do milling-pcb work (with a dremel type head) , so they start with a plain of copper on top of pcb board, and cut away the space between the traces you need. This can actually work quite well on certain designs, and has the added benefit of being able to drill holes. And most design software allows "zones" that mean you're not cutting a ton of stuff, you're merely cutting away space between parts that need to be electrically separated [I'm repeating myself].
