Now available – Virgin Black PLA at no extra charge
by Vik Olliver
One of the common things plastics manufacturers do – including us – is to recycle the remains of a coloured run into the black, traditionally run last. It looks the same because it’s all loaded with carbon black pigment. We don’t need a photo of black do we? Good.
This is a sensible environmental behaviour, but makes the melting point of the black a little variable as it will have other pigments mixed in with it. All the different colours have slightly different melting points and viscosity, as they’re all – pretty obviously – different materials.
So, as we get a lot of perfectionists using our PLA who want it to do exactly the same thing every time, we’ve marked some pristine batches of 1kg Black spool just for them. You can now request our “Virgin Black PLA” if you e-mail sales at the time of your order, though stocks are limited – on the plus side, no extra charge! Do give us your feedback on this one.
