Mostly stock Filastruder v1.6 vertical extrusion with full barrel insulation, header wrap, melt filter, Filawinder
Extrusion:
Temp: 189c
Rate: 8-11"
Average diameter: 1.73mm +/-.02mm
Printer:
Solidoodle 2, E3D Titan extruder, E3D v6, E3D Volcano w/.6mm nozzle, direct Y drive, Lawsy carriages, DRV8825 driver on E, mirror and Aqua Net.
Mixing:
For powder based colorant, you only use 2g of colorant per 500g of virgin pellets. For this, I used about 460g and just shy of 2g...perhaps 1.9g, but unfortunately my scale only allows for one sub-decimal digit, so I had to estimate. As you dump in the powder, you will notice there are some pellets similar to masterbatch, but these specific pellets are to ensure bonding. If you are preparing or saving for multiple batches over just one bulk roll, don't try to pick them all out at once, just let the fall in as they may...with reason.
Once dumped into a mason or thoroughly cleaned out pasta sauce jar, begin to shake. As with all powder based colorants, you will notice the pellets change color within second, but you should continue shaking for 10 minutes or so. The longer you shake, the better the colorant bonds to the pellets.
Printing:
Printing went just as smooth as any other ABS I've extruded from my
Filastruder. Here is a center part for a spool. 
Printed .3951mm layer height
2 perimeters, 90% infill
232c for extruder, 97c for bed
Comparison to available filament:
I have never bought Powder Blue filament, nor have I ever seen it by any reputable filament brand.
Takeaway and comments:
As previously stated, the quality is just as good as anything provided by a Filastruder, and more reliable than most ABS filaments on the open market. The Powder Blue powder based colorant does not cling to the glass of the jar as much as the red, so if you use the same jar for mixing many powders, cross contamination with any other color than white would be negligable or non-existent.
As with the red I reviewed, there was Zero color banding noticed during extrusion or printing!
I mentioned in a reply to my first review of red powder colorant here that staining is a risk with powders. Please do not experiment with these colorants over carpeting. Over the bathroom sink is the best place to add the powder, or pour the powder+virgin pellets into a smaller vessel like I do for mixing. If you experience staining, dish soap and water or diluted bleach will clean it all off with little force. Powders provided by OS3DP.com can be used for PLA, ABS, HIPS, PC, and Nylon.
