Print Tips
This material requires an enclosed printer and an all metal hotend to properly print.
Print slow and hot to help with layer adhesion and warping.
Keep cooling fans off.
Set build plate temperature to 105˚C for 10-15 minutes before starting the print to allow the chamber to heat up.
A dry box or filament dryer is recommended when printing with PC due to it being slightly more hygroscopic.
Using a larger diameter nozzle will also help with layer adhesion.
Magigoo PC is a great product to help with polycarbonate build plate adhesion.
Annealing is required after printing polycarbonate, especially if you do not have an heated chamber of 90˚C+. Anneal with your oven at 90˚C for 2 hours.
You need to put the print into the oven right when the print finishes and not allow it to cool.
FAQ
Does PolyMax™ PC need to be annealed?
Annealing is the process of heating up the printed parts at a certain temperature for a certain period of time. You can anneal PolyMax™ PC at 90˚ for 2h.
The purpose of annealing PolyMax™ PC is to release the internal stress which accumulates during the printing process. This internal stress can creates micro cracks over time and weaken the part.
(NOTE: In the case of semi-crystalline polymers such as Nylon, annealing purpose is mainly to crystalize the material for better mechanical and thermal properties)Does PolyMax™ PC need to be annealed?
Will the spools work in an AMS?
Yes! We have redesigned the edges of our spools so all Polymaker products will now spin great in the AMS.
Does PC absorbs moisture?
The short answer is yes, PolyLite™ PC will absorb moisture slightly faster than regular PLA. We recommend using a dry box to achieve high quality and strong prints.
Why are my parts cracking along layer lines?
You really need to make sure you are using an enclosed printer and that you are keeping ambient air temps as high as possible. You then want to make sure you are annealing the part the moment the print finishes. Keeping ambient air temps high and allowing for very slow cooling is a great way to reduce chances of cracking and to maintain layer strength.
What is the best surface adhesive for PolyMax™ PC?
In our experience we had excellent experience with Magigoo PC. This special glue allows great adhesion when the build plate is hot and easy release when the build plate cools down.
Printing Requirements
Enclosed printer that can trap heat required.
Actively heated chamber highly recommended. Minimum 60˚C chamber temp highly recommended.
Large, dense parts will require a heated chamber.
Dryer or drybox recommended.
Magigoo PC highly recommended to help with bed adhesion.
