3D filament ROSA3D PC/PBT-BLA-175-05-RO 1.75 mm, 0.5 kg, Black (PC/PBT blend)

The ROSA3D PC/PBT filament is a high-performance engineering material designed for FDM 3D printing, combining the mechanical strength of polycarbonate with the chemical resistance and flexibility of polybutylene terephthalate. This 1.75 mm black filament is supplied on a 0.5 kg spool and is engineered to provide excellent dimensional stability and impact resistance, making it an ideal choice for demanding industrial applications.

Advantages

This PC/PBT blend offers a superior balance of properties, including high thermal stability and resistance to various chemicals, which are often required in harsh environments. The material exhibits excellent layer adhesion and structural integrity, ensuring that printed parts remain durable under mechanical stress. Its unique composition minimizes warping compared to pure polycarbonate, allowing for more reliable printing of complex geometries and functional components.

Suitable for

• Functional prototypes requiring high mechanical strength
• Mechanical parts exposed to chemical substances
• End-use components for automotive or industrial machinery
• Durable housings and protective covers

This filament may not be suitable for beginners or those using entry-level 3D printers without a heated chamber, as it requires high printing temperatures and precise thermal management to prevent warping. It is also not recommended for applications requiring high transparency or extreme flexibility, as the material is rigid and opaque.

Key specifications

• Material: PC/PBT blend
• Diameter: 1.75 mm
• Weight: 0.5 kg
• Color: Black
• High thermal resistance
• High chemical resistance
• High impact strength

How to use

To achieve optimal results, ensure your 3D printer is equipped with a hardened steel nozzle and a high-temperature hotend capable of reaching the required extrusion temperatures. The print bed should be heated, and the use of an adhesive or a brim is recommended to improve bed adhesion. It is highly advised to print in an enclosed chamber to maintain a stable ambient temperature, which helps in reducing internal stresses and preventing delamination during the printing process.

What to consider before purchase

• Ensure your printer supports high-temperature materials
• Check if your printer has an enclosed build chamber
• Verify that your extruder is compatible with 1.75 mm filament
• Consider the need for a hardened nozzle due to the material's abrasive nature

Usage recommendations

For the best structural performance, orient your parts to minimize support structures and optimize infill density based on the intended mechanical load of the final component.
