Review on Proto-Pasta Matte Fiber Gray HTPLA by Jeremy May

I use this filament regularly at work when I need a part with some electrostatic dissipation properties. While I don't think it's worth using as a conductor, it works well in that capacity. Also, it has such a nice matte finish that my colleagues sometimes buy it just for that. With a little sanding of the details, you can get a much more professional look than the typical glossy rollers. Because it contains amorphous carbon, it can delaminate more easily than regular PLA, so keep that in mind. used, it comes in a cardboard tube that not only works perfectly, but is also fully biodegradable. We print a lot and make a lot of coils from other brands that aren't even recyclable, so that's a bonus on top of the biodegradability of PLA itself.
