3D printing filament Flashforge FLB1 1.75 mm Black 1 kg

Flashforge FLB1 1.75 mm Black is a 1 kg spool of 3D printing filament designed for use with FDM/FFF printers that accept 1.75 mm diameter material. The filament provides a consistent feed from the spool and a uniform diameter suitable for prototyping, functional parts and hobby printing. Material-specific print settings such as nozzle temperature, bed temperature and print speed depend on the filament formulation and the printer model.

Advantages

This 1.75 mm black filament offers steady extrusion and dimensional consistency to reduce print failures caused by irregular filament diameter. The 1 kg spool balances usable material quantity with compact storage and handling. Its black color gives high contrast and is suitable for parts where a neutral, non-reflective appearance is required. The filament is compatible with a wide range of consumer and prosumer FDM/FFF printers that accept 1.75 mm filament.

Suitable for

• Rapid prototyping and proof-of-concept models
• Functional components and replacement parts
• Hobby models, miniatures and decorative items
• Testing printer calibration and extrusion settings

Key specifications

• Diameter: 1.75 mm nominal
• Spool weight: 1 kg of filament
• Color: Black
• Filament type: consumer FDM/FFF-compatible filament (verify material type with seller)
• Packaging: filament wound on a single spool for direct printer feeding

How to use

Install the spool on the printer spool holder, feed the filament through the extruder path and load it according to the printer manufacturer’s filament-loading procedure. Set nozzle and bed temperatures, print speed and cooling based on the filament material and the recommendations for similar materials; perform a temperature tower or test prints when switching to a new batch. Ensure the filament path is free of tangles and that the spool can rotate smoothly to maintain consistent extrusion.

Usage recommendations

Store the filament in a dry environment away from direct sunlight and humidity to maintain print quality. Before printing critical parts, run calibration prints and adjust retraction and flow settings as needed for your specific printer and hotend assembly.
