Print Tips
This material should only be printed when you have a heated chamber printer that can reach 90˚C - 100˚C ambient air temperatures.
This means this is an industrial material that should not be printed on standard consumer machines.
Print slow and hot to help with layer adhesion and warping.
Keep cooling fans off
Set the chamber temp to 90˚C - 100˚C and allow the chamber to heat all the way up before starting your print.
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.
You need to keep your chamber temp at 90˚C - 100˚C for 2 hours after the print finishes. Then allow the print to slowly cool to room temperature.
FAQ
Has PolyMax™ PC-FR been tested by a third-party?
Yes, PolyMax™ PC-FR has been tested by SGS-CSTC Standards Technical Services Co., Ldt.
Test Method: IEC 60695-11-10:2013/Cor.1:2014 Method B
Result: Classification: V-0
Does the FR affect the mechanical properties?
Yes, the FR additive will make the material less ductile which means a higher tensile strength and Young's modulus (more rigid). However the PC will maintain its great impact and high heat resistance.
More information in the technical data sheet below.
What is annealing?
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.
Printing Requirements
All-metal hotend that can reach at least 260˚C.
Enclosed printer that can trap heat required.
Actively heated chamber with minimum 90˚C chamber temp required.
Large, dense parts will require a heated chamber even more so than small parts.
Dryer or drybox recommended.
Magigoo PC highly recommended to help with bed adhesion.
All-metal hotend that can reach at least 250˚C recommended
