It took about a month for the reprapper admin to ship the spools to me after emails back and forth but they did fix their order. I cant say anything about the quality yet. I've only been able to print a temperature test box and a .5mm thin wall box, I'm having problems with their Black PLA sticking/clumping on my extruder tip during any infill. So far they measure out to around 2.82mm diam, look well enough, wrapped in plastic and have moisture absorbant pellet bags they are shipped with. My thin wall piece seemed to look well enough, if I can get the rest to print decently I'll add more input.
:A little I noticed about the reprapper black 3mm PLA so far- it melts well at low temperatures. It was melting well at 160, but since cold extrusion stop kept being called, I've been using 175-180 as the better print temperatures. I had issues getting the first layer to stick well, but I am unsure whether that is because of the filament temperature or the fact that its sticking to my extruder instead any chance it gets (and then begins mopping up layers) at 210 the black would occasionally steam, so I am calling 200 as my top end temperature, but print quality begins to degrade after 185.
:After handfuls of tests and remeasurements, I found that this filament was varying in its diameter every 2-3 feet or so by .05mm. I was able to get a really beautiful set of first layers, walls, perimeters and infills... until the solid infill cover. This seems to be a common occurance with many of my prints before, but to a much lesser degree than now- instead of simply bridging over the gaps, the filament sticks to the extruder head, pools up and makes a big puddle of molten plastic, mopping up layers and spilling over everything.
:I have given up on the Black reprapper PLA until I can find a fix for cooling properties for PLA, either a fan attachment or trying a different extruder. I believe the largest factor I'm seeing is its need for more cooling.
Instead, I have tried a few test runs with Taulman's 618 nylon, which runs much lower temperature than stated on his website. I am getting results with it at 200C, even though theres a lot of room for improvement. I've ordered a garlite plate from McMaster Carr but I doubt it will be the end product for an ideal print bed. I made a really impressive 608 BB ball bearing, but otherwise I cant get very reliable looking prints yet.
