#1 ProMolt PLA 3D Printer Filament (1.75mm Diameter, 1kg (2.2lb) Spool, +/- 0.05mm Tolerance, Professional Quality)
My $70 3D printing pen model worked great. It's supposed to detect the difference between PLA & ABS and heat accordingly. I've noticed it doesn't do that great with ABS, but just fine with PLA. It works like a champ in this pen and I've already made some fun designs.
My $78 3D printing pen model wouldn't work with this at all. I was actually surprised at that-the cheaper one is....well....cheaper. But it had no problem loading and writing. This model could barely load this stuff and only a tiny bit came out the tip but it just wouldn't draw. I went back and forth between this filament and some I already had and there were no problems with the other filament working right. I thought it's odd that the temperature for PLA is so high, this pen recommends only 175 for PLA. Assuming it wasn't hot enough, I even turned it up to 235 degrees and it still wasn't coming out well. Your clue is as good as mine as to why a more customizable and expensive pen wouldn't take this but a cheaper pen would.....
I'm disappointed I can only use this in one of my pens (the one I don't like quite as well) but I will still happily use it for future projects. It has a beautiful glossy look to it as it mentions in the description. To check out the 3D filament go HERE. #promolt3d
