I got one for some glow in the dark abs I got in a sample pack.. And was just wondering… Is there a reason I should just leave it on all the time? Or should I go back to brass after I’m done playing with this.Edit: my theory is that the nozzle stays a little cooler so the plastic comes out a little cooler… With everything set up properly it might end up having a better print quality…So is anyone out there willing to try on a printer? I’d do it… But I’m quite new.. And would not be able to achieve similar results across that much of a change… http://ift.tt/1VIOl6Q
