Actualy this forum is for hobbyest people,so most of guys in her has homemade or other small filament makers,thease small machines has a very small comperssing chambers and mixing in such machines is not a good idea,i m sure most of guys have problems with coloring pellets,sometimes a small part of the coloring pellet is extruding alone.

Even the colorant pellets that we buy it from professional stores and manufactors are not suitable for our small machines!!!!
The best logical easy solution that i did already try it and it works 100% and i like to share it with other is.

Very simply,put the pellets u need to color in any botte or container and drop some liquid dye"i did use the dye that it is specialy making for wood dying,any liquid dye will work well"and shake the bottle very well so all the pellets will be equaly dying from the surface and than you can use it in ur filament maker.

This is the fastest easy way to color any filament!!!!with a perfect professional result!!!and stop teaching each other complex crazy ways that takes lots of effort and time with a very bad result!!!

I m sory for my bad english,hope every one will use my filament colorant method good luck!!!
