3D Pen Filament Refills PLA(16 Colors, 40 Feet Each)

Put this in my brand new pen and it jammed the pen really bad. A big chunk of unmelted PLA was stuck in the tip. Heating it up to 230F did nothing. I had to take the tip out and use a dremmel to get it out, put the whole tip in the oven at 190F to see if I could get it out and nothing. When I finally drilled the chunk through, then I was able to get the piece out by sticking a pin inside and pulling it out. Sure enough looked like it never melted, just a nice tube, smooth stuck in there, no melting at all. No wonder it jammed. Used the filament that came with my pen and it worked great with no jams. This wasn't cheap either. Now I got a bag of PLA with no use.

This is a nice assortment of filament, in a wide spread of colors.I bought this to send with a 3d pen that I bought for my nieces and nephews, so have no idea how well they will print.That said, the filament arrived quickly and well packaged, each color in individual bags, and then bundled in a larger bag.

I actually bought this pack to have a variety of color options for a Alunar M680 3D Printer and they have been working great. Each color has made many items, so we're very happy.

These refills work perfectly with the seller’s corresponding pen. For the emoting receivedand theprixe I paid I am very pleased. No concerns!

Can't wait to give to my very artistic granddaughter for Christmas!

Works great with our Uvital 3D pen. This set is a must-have for anyone with a 3D pen

Works well. Good price

I’m still learning and these colors are making it way too fascinating to stop
