Well, it's been a busy few days.

While not the results I wanted to show you by now, I can say I'm making progress. What I've been doing is going through all the variables involved and working on charting out the results. I'm concentrating on ABS right now simply for the reason I have a lot of it and the solvent is a lot better for my health than some of the others. Not saying healthy, mind you, just better.

Main thing to getting smaller fibers is solvent ratio, combined with feed rate and Hv level. Length is somewhat controllable by plate distance from emitter, but to a lesser degree. So for three days of work I think I've made progress getting a better feel for running it. I'd also like to add that the goal of making it get repeatable results has been met. The same settings are giving me the same results, every time. So that's a good thing.

Here's a couple of pics of a fiber I found interesting. The white line is a fiber slightly smaller than a human hair. You can see where I found a section that shows that it's actually made up of a bunch of smaller fibers. Pretty cool for what I want to do.

The other pic is where I followed the fiber to it's end. It also shows the smaller fibers it's made up with.

The settings that made this fiber are real close to what I want for the main run I wanted to make this last week but got delayed. If it all works out I'll be showing you conductive ABS in the next few days. :)

Oh, and by the way, the blue background is because I used a piece of painters tape to collect the fiber. Seemed like a good way to pin the darn thing down, and the tape was handy.
