I just made my first prints in PLA loaded with carbon fibers ...
Some people claim that they are volatile during printing so that you have to ventilate the room well (I would have a hard time putting the tronxy at the back of my living room) ... I don't really believe it.
But effectively with the carbon filament:
- there are some fibers in the "waste" filament
- the smell of VOCs is stronger than with the other PLA yarns that I have used recently (same brand)
Care should be taken when actually reworking these pieces (like Dremel).
Otherwise the 0.4 and 0.5 mm nozzles end up clogging sooner or later on my printer (tests over the entire temperature range: from 190 to 250 ° C) ... so I have been printing at 0.6 since yesterday and there it seems to go. The parts will be less precise and thicker (wall at 2 * 0.6 = 1.2 instead of 2 * 0.4 = 0.
but the finish is generally not what is required of a carbon print which must above all be resistant.
