Hey, i´ve got a Problem! I try to colour my printed parts. First of all i wash the parts with aceton. Afterwards I put them into a solution with water and rit dye. But if I try to colour them black they are getting a little brown as you see in the picture.Even if i put more dye to the solution nothing changes. DO you guys have any idea how t osolve my problem??by lukas9488 - Polymer Working Group
