PC filament is made with polycarbonate. It is popular because it is resistant to heat, very tough, and it has optical clarity. It is commonly used to make safety glasses, DVDs, and bulletproof glass. Although the products that you make are strong and durable, it can be a difficult filament to work with. It is hygroscopic, which means that it can absorb water. It must be kept sealed in an environment with low humidity.
Printing with PC Filament
Printing with PC filament can be tricky, so it is important to follow the guidelines given by the manufacturer. Generally, the nozzle temperature should be between 260 and 310 degrees Celsius. The bed temperature should be between 80 and 150 degrees Celsius, and the fan should be turned off when you start printing.
This material softens slowly when it is printed, so it is better to print at lower speeds. Faster speeds will require a higher temperature.
It is important to note that it can have severe warping if it cools too quickly, and it will have fumes. The key is to make sure that the printing bed is the right temperature so that it doesn’t cool too quickly. In addition to warping, layer splitting can occur.
Benefits and Features
This heavy duty thermoplastic filament is one of the most common 3D printing materials, and it has the following benefits and features:
- Makes stiff and rigid 3D parts
- Resistant to impact
- Very strong and durable
- Flexible at room temperature
Uses for PC Filament
People use PC filament when they want heat resistance and toughness combined with optical clarity. Some popular applications are safety glasses, DVDs, electronics cases, sun glass lenses, and bulletproof glass, among others. In addition, it works well as an electrical insulator because it is resistant to heat. This filament produces strong, translucent prints, which work well for those products.
When people use this material, they find that the first layer is critical to success. If you use slow, thicker extrusions on the first layer, the rest of the layers have better adhesion. It is important to note that the higher temperatures that are required for printing translate to drooping if the material that is printed is not supported.
In addition, this material is bendable at room temperature. It will bend before it breaks, which is beneficial when you are making these types of products. It also transmits light better than other thermoplastics.
