# PolyLite™ PC

**Engineered Polycarbonate for 3D Printing**\
PolyLite™ PC is crafted from a polycarbonate resin specifically designed for 3D printing, ensuring reliable performance and ease of use. This formulation provides excellent stiffness and heat resistance, making it suitable for demanding applications.

**Light Diffusing and Translucent Properties**\
With its impressive translucency, PolyLite™ PC allows light to pass through, making it an excellent choice for projects that require light diffusion or aesthetic illumination effects.

**Simple Printing with Enclosure**\
For best results, print PolyLite™ PC in an enclosure that traps ambient air. This helps maintain stable temperatures and produces stunning, high-quality prints with minimal warping.

**Ideal for Functional and Aesthetic Parts**\
Choose PolyLite™ PC when you need a filament that combines stiffness, heat resistance, and beautiful translucency - perfect for both functional components and visually striking models.

## 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

<details>

<summary><strong>What is annealing?</strong></summary>

You can find out more about annealing [HERE](/printing-tips/post-processing/annealing.md)

<summary><strong>Will the spools work in an AMS?</strong></summary>

Yes! We have redesigned the edges of our spools so all Polymaker products will now spin great in the AMS.

<summary><strong>Does PolyLite™ PC absorbs moisture?</strong></summary>

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.

<details>

<summary><strong>Why are my parts cracking along layer lines?</strong></summary>

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**

* 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.
* Annealing post printing. [More info on annealing](/printing-tips/post-processing/annealing.md)
* Dryer or drybox recommended.
* Magigoo PC highly recommended to help with bed adhesion.
* All-metal hotend that can reach at least 250˚C recomended.
