[ABS Colorant] - Silver (3D Supply Source)

Extruder type: Standard Filastruder with 1.75mm melt filter, full barrel insulation, hopper shaker, and vertical setup with winder.
Picture of my set up:

On the winder laser sensor, I added straws where the PTFE goes to help guide the filament better.

Printer type: SD2, E3D v6, Bulldog XL, Glass bed, and Lawsy's Carraiges.

Mixing ratios
I usually use 1 colorant pellets to every 96 ABS pellet. Since I do not want to count each and every pellet (no one else wants to either), I ended up converting the 1:96 ratio into weight, and I ended up with 56 grams of ABS for every 1 gram of colorant. A benefit of using the weight system, is you do not have to worry about differing colorant pellet size. How did I get that number? Time for some math! 80 ABS pellets = 1g and 56 colorant pellets = 1.2g. Lets say you have 56g of ABS and you want to figure out how much teal colorant to add in order to get a 1:96 ratio.
1. Multiply 56g by 80 (this gives you the amount of total pellets) you get 4480
2. Set up a proportion like this: x/4480 = 1/96. Solve the proportion and you get 46. (you can skip the proportion and divide by 96 too)
3. Multiply 46 by 1.2 and divide everything by 56. You get 1 at the end of all that. The last number, 1 in our case, is the number of grams you need to add.

Tips and tricks for colorants:

• Make sure to mix your colorant evenly with the rest of you plastic

• To get awesome color consistency you need to use really fine colorant or chop up and re-extrude.

• Some colorants dramatically slow extrusion, and mixing colorants usually leads to extremely slow extrusion

• Big colorant pellets = horrible color consistency and the other way around too.

• The Filastruder is perfectly capable of producing consistent colored filament. If you are getting color banding try the following: Decrease pellet size, add more colorant, or increase extrusion temp. Usually the problem is with pellets being too large and not mixing evenly.

Extrusion
Extrusion temperature: 190°C
Extrusion rate: 1 inches per minute.
Average diameter of filament: 1.67mm
Tolerances: + or – 0.06mm

Comments
I got this from http://3dsupplysource.com/. Soon after loading this colorant up into the Filastruder, my extrusion rate slowed dramatically to less than 1 inch per minute. Figuring the Filastruder would sort itself out, I let it extrude all day, but to my dismay the extrusion rate did not increase. This may have been a problem with my system since I had previously run copper colorant, and the two could have mixed thus slowing extrusion. The color consistency was not too bad with this colorant even though the pellets were quite large.
Printing
Setting my glass bed to 104°C, the hot end to 240°C, setting the extrusion multiplier to 150% for the first layer, and using a coat of PVA glue worked very well against warping. This is a very easy material to print. Agian, I had a skip on the Y axis on this print, but I got it sorted out. No problems with delamination

Brittleness
1-10 scale, 1 is TPU and 10 is acrylic. 6
Layer bonding
1-10 scale, 1 is Nylon and 10 is acrylic. 5

Comparison to commercial ABS filament: N/A ( I have never bought a roll of ABS filament thanks to the Filastruder)
