Here's a better shot. Unfortunately I'm using glow-in-the-dark filament and it's translucency qualities make for difficult photographs. Also, with a microscope, unless you do a complicated multi-focal set, you can't get good depth of field and I don't have time for that right now. I will do one when I use a more opaque filament sometime soon though. But, you can still see the matrix that is formed. It's super strong and I think a superior method of infilling.
