All that I can tell is that it comes from Colombia, it's white
and you can eat it if you want. WOAAAA hold on, it's not what you
think :)
It's maltodextrin, I just mix about 10 to 15% to Plaster.
too much and it makes a big mess, glues everything,including the
rails ,print head , feeding bin etc.....
also, if you add too much of it, the plaster starts to curl when
printed,and the parts will look like a surf board.
it works very well at 600 dpi, but i guess it depends on the
printer head, some have bigger ink drops then others.
I'm happy with lexmark,it has a big black ink cartridge (30ML)so I
can print a Porsche model that's about 5x5x2 inches and a layer
thickness of 0.004" and still have ink left for another part before
refill it.
