In this month’s tech note I wanted to discuss a question that has came up several times in our chat channel concerning choice of filament color.  We recommend that you do not choose white or black as the filament color if you are new to 3D printing. There are a couple of reasons for this that I will try to explain.
The first would be regarding black filament.  When first learning to use your printer getting your hotend temperature set properly can be a bit tricky. To get the best setting requires looking at your test prints and determining if you need to increase or decrease your temperature. The black color can make it difficult to see the subtle difference.

With white filament its even a bit more tricky.  The pigments used in almost all white filament change the flow characteristics as well as being difficult of seeing the subtle differences that temperature can make. Concerning the flow issues it has to do with back-pressure, the white filament has more viscosity and can drive you nuts trying to fine tune. This issue can be seen on the image in this article.

For users new to printing, the artifact can be difficult to minimize.  Bowdens style extruders amplify this issue.

For people new to 3D printing choosing a color such as blue, red, green, yellow will make it much easier to learn to print instead of fighting issues related to color specific problems.
