Bambu Labs PC (Polycarbonate) is a high-performance thermoplastic material specifically engineered for 3D printing applications requiring high impact resistance, toughness, and thermal stability. Polycarbonate is known for its outstanding mechanical properties and is widely used in various industries including automotive, aerospace, and consumer electronics.

Physical Properties

  • Density: Typically around 1.2–1.22 g/cm³
  • Heat Deflection Temperature (ISO 75 0.45MPa): 112°C
  • Tensile Strength: Exceptionally high, often in the range of 9,000–10,000 psi (or 62–69 MPa) depending on specific formulations

Aesthetic Quality

Polycarbonate filaments from Bambu Labs usually exhibit a glossy, transparent or translucent finish, although opaque variants may also be available. The material offers a high-quality aesthetic suitable for both functional and display pieces, contributing to its broad range of applications.

Durability and Usage

Bambu Labs PC is renowned for its high impact resistance, toughness, and thermal stability. The material is also resistant to various chemicals, making it ideal for use in challenging environments such as industrial settings, automotive components, and high-performance engineering applications.


Polycarbonate can be post-processed through a variety of methods such as sanding, machining, and painting. However, due to its high mechanical and thermal resistance, specialized tools and treatments may be required for optimal results. The material is also known for its good adhesive properties, which facilitate bonding and assembly of multi-part models.

Environmental Impact

Polycarbonate is not biodegradable and is derived from petrochemicals, which makes it less eco-friendly compared to materials like PLA. However, its long-lasting durability can offer some environmental benefits by reducing the need for frequent part replacements. Proper disposal or recycling is encouraged to mitigate its environmental impact.

In summary, Bambu Labs PC filament is a high-performance material that offers exceptional mechanical properties, making it a top choice for demanding industrial and engineering applications. While it may not be as eco-friendly as some other materials, its high durability, impact resistance, and thermal stability make it an indispensable option for specialized, high-stress tasks.
