Hy friends. I am facing a problem. I have a medium sized abs filament production unit pf capacity 4kg/hour. I have a hot water tank with hot water at 65 degree Celsius and length of tank is 5 feet. My extruder ejects the melted abs at temperature of 170 dgree. After all this arrangement my filament is still not round.
Dear friends.. I a a filamant manufacturer from India, I have setup a small filamant production machine (30m/min). I am manufacturing it for 3d pen. I am facing a problem.. When I make filament of pure abs with no colour added, it prints fine... but as soon as I add up some pigment in it, it starts giving alot of bubbles. And it happens only when I add pigment in the abs..
