PLA 3D printer filament Renkforce RF-5771490 1.75 mm 1 kg Black

Renkforce RF-5771490 PLA filament is a 1 kg spool of black 1.75 mm thermoplastic designed for FDM 3D printers. Made from polylactic acid (PLA), this filament offers straightforward extrusion, low shrinkage and reliable layer adhesion, making it suitable for hobbyists and prototype development. The material is rigid and biodegradable under industrial composting conditions, and it produces parts with good surface detail and dimensional stability when printed with appropriate settings.

Advantages

This PLA filament prints at moderate extrusion temperatures and exhibits low warping, reducing the need for heated build plates or enclosed printers for many prints. The 1.75 mm diameter provides consistent feeding on most consumer and prosumer FDM printers. Black pigment delivers uniform colour and helps conceal layer lines in many applications. The spool size of 1 kg allows for multiple medium-sized prints without frequent spool changes.

Suitable for

• Prototype models and proof-of-concept parts
• Hobbyist figurines, miniatures and decorative objects
• Functional small parts where rigid material is acceptable
• Educational projects and classroom demonstrations

How to use

Load the filament onto the spool holder and feed it through the printer's filament path to the extruder, ensuring the diameter matches the printer setting. Set the nozzle temperature according to your printer and PLA material recommendations, typically in a moderate range appropriate for PLA, and calibrate extrusion multiplier and print speed for consistent flow. Use a build surface appropriate for PLA or a lightly heated bed if required to improve first-layer adhesion, and perform test prints to fine-tune retraction and cooling settings for optimal surface quality.

Usage recommendations

Store the filament in a dry environment and, if possible, in sealed packaging with desiccant to maintain printability. For best results, verify printer calibration, use adequate part cooling for detailed prints, and avoid prolonged exposure to high temperatures and humidity to prevent degradation of filament performance.
