Polycarbonate (PC), in addition to being the strongest 3D printer filament presented in this list, is extremely durable and resistant to both physical impact and heat, able to withstand temperatures of up to 110°C. It’s also transparent, which explains its use in commercial items such as bullet proof glass, scuba masks, and electronic display screens.
Despite some similar use cases, PC shouldn’t be confused with acrylic or plexi-glass, which shatter or crack under stress. Unlike these two materials, PC is moderately flexible (though not as much as nylon, for example), allowing it to bend until eventually it deforms.
PC 3D printer filament is hygroscopic, able to absorb water from the air, so remember to store it in a cool, dry place to ensure better quality prints.

When Should I Use PC 3D Printer Filament?
Due to its physical properties, PC is an ideal 3D printer filament for parts that need to retain their strength, toughness, and shape in high-temperature environments, such as electrical, mechanical, or automotive components. Also try to take advantage of its optical clarity in lighting projects or for screens.
