pvc printing

we had a man at work today redoing the floors and he was using a plastic welder to seam the pvc sheets together. I had already been talking to him about my printers so when i started looking at his filament he offered me about 10' of it to try. Has anyone ever tried using pvc weld wire before?

... it's working, but you have to ventilate the building-area and the surrounding room, as the fumes when heatin/overheating PVC are highly toxic

I tried it, but ended up baking it in the extruder, ended up with burnt crumbly residue. I think it may have extruded properly at first but not sure, didn't get as far as testing adhesion to print bed, warping etc.

I think it has a low thermal stability, so it can be taken up to the melting point, but if kept there for to long will do strange things to the polymer.

I tried to find the temp settings i used, but can't sorry.
