This material only has a requirement that you print with an all metal hotend that can reach 250˚C or higher. Tips: Do not set your build plate above 50˚C and keep any chamber doors open. If you let the build plate or ambient air get above 50˚C, you run the risk of warping or ugly prints. Use a glue stick or Magigoo PA if experiencing any issues with bed adhesion. CoPA can be difficult to print overhangs with, so it is recommended that you try and design your part to have the least amount of overhangs as possible. CoPA can be pretty temperature sensitive, so it may require some tweaking to get the correct printing temperature for good surface quality. CoPA is very hygroscopic and therefore should only be printed while kept in a heated filament dryer the entire time you print. If you hear "popping" or "cracking" noises, then the filament needs to be dried. This needs to be annealed after printing at 80˚C for 6 hours. After annealing - the part will be dried out and therefore need to be moisture conditioned. Moisture conditioning will happen even if you do nothing as the material absorbs moisture from the air. To speed up moisture conditioning, keep in a humid environment for 48 hours.
