I recognize that your parts are for a non life threatening, or life support application, and that there are sources of quality black plastic.
In hindsight, I may have used the word never too strongly.
It stems from my experience designing medical devices, where black plastic is typically avoided.
There are lot's of consumer products made with black plastic, which are of a high quality.
I have read in these forums complaints of users having trouble processing black plastic.
I surmised that their difficulties were due to using black filament that contained recycled plastic.
I have no aversion to purchasing black plastic for my own use, or specifying black plastic parts for non medical use.
Fillers, and recycled plastic can be blended into black plastic more readily than say a white plastic, and in most cases have no ill effect.
I have ideas to electroplate printed objects, and black plastic could pose a problem if it has fillers, and/or recycled plastic (I'm not referring to regrind plastic).
Without material certification you will not know if there was filler or recycled plastic added, other than to test the material.
An all black delta printer would look pretty cool(tu)
