Colour-changing filament by brand

Guides

• Best PLA filament in the UK: how to choose
  The best PLA filament is the one that prints reliably at the lowest price per kilogram, not per spool. How to judge tolerance, spool type, refills and PLA+ before you buy.
• Carbon fibre filament explained: is it worth it?
  Carbon fibre filament is ordinary plastic filled with chopped carbon fibres. It prints stiffer and with a matte finish, but not necessarily stronger, and it needs a hardened nozzle.
• Does glow in the dark filament really work?
  Yes, with caveats the listings leave out. How bright it gets, how long it lasts, which colour glows best, how to print it for the strongest glow, and why it eats brass nozzles.
• Is PLA food safe? The plastic vs the print
  PLA as a plastic is used in food packaging, but a 3D printed PLA part is not certified food-safe. The real concerns are layer lines, the nozzle, additives and heat, and what people do about them.
