On a whim I actually bought some flexible filament when I ordered extra heater/nozzles. That was a mistake! I knew better that but I really wanted to try flexible material. I am so disappointed in the quantity which I misread or misunderstood for $12 + shipping. It's not the color that was shown on the website and I measured a foot short. Okay, color isn't a deal breaker, I just wanted to try out the properties, but the quantity isn't enough for a real project.
So Friday my (side work) client put the project on hold, so I knew I was going to have a long, boring, rainy weekend at home because mom & I are in the 2nd week of a cold and it's supposed to rain for a week. I'm over the cold but not the cough. On the way home on Friday I picked up a roll of flexible 3D filament for $36, 3 times the price of sample filament. I have a couple projects in mind that need the qualities of what I thought was flexible filament -- not exactly what I thought.
Ugh, it was a rough start. I thought I was going to need a real 3D printer and water-soluble support filament to do anything with it. Then I thought I broke the pen -- the motor part that pushes material to the heated tip -- whew. No, I was just experiencing typical issues with flexible material. When it's hot, it's a lot softer than I expected. Then it takes longer to set up, meanwhile it sticks to anything it touches.
Here's formerly "Nekkid Barbie's" best side trying on some flexible filament. I'm afraid she has a new minor burn scar from the heat on her butt, looks more like rug burns.
