Filament ROSA3D ReFill PCTG Black 1.75 mm 1 kg — ROSA3D

ROSA3D ReFill PCTG Black 1.75 mm is a 1 kg spool of PCTG thermoplastic filament designed for FDM/FFF desktop 3D printers that accept 1.75 mm filament. This black filament offers the balance of toughness and dimensional stability expected from PCTG, making it suitable for printing functional prototypes, mechanical parts and end-use components where impact resistance and reliable layer adhesion are required. The spool format and consistent diameter support uninterrupted feed and predictable extrusion behavior across typical consumer and prosumer hotends.

Advantages

PCTG provides higher impact resistance and better chemical resistance than standard PLA while remaining easier to print than some engineering-grade polymers. The ROSA3D ReFill PCTG Black filament exhibits good layer adhesion, low warping tendency and consistent filament diameter for stable printing. Its black color masks internal structures and is suitable for parts where a neutral, professional appearance is preferred.

Suitable for

• Functional prototypes and concept models that require toughness
• Mechanical components such as brackets, clips and housings
• End-use parts exposed to occasional mechanical stress
• Parts that require good dimensional stability and low warping

Key specifications

• Material: PCTG thermoplastic
• Diameter: 1.75 mm
• Spool weight: 1 kg of filament
• Color: Black
• Compatibility: FDM/FFF desktop 3D printers accepting 1.75 mm filament

How to use

Load the spool onto the printer spool holder and feed the filament into the extruder according to your printer manufacturer’s instructions. Select printing temperatures and cooling settings appropriate for PCTG—start with manufacturer-recommended nozzle and bed temperatures for PCTG or similar materials and fine-tune based on print results. Ensure proper bed adhesion using an appropriate build surface or adhesion aid, and calibrate flow rate and retraction to reduce stringing while maintaining good interlayer bonding. Allow printed parts to cool gradually to minimize internal stress.

Usage recommendations

For best results, print with a heated bed and moderate cooling. Typical starting settings are a nozzle temperature in the range commonly recommended for PCTG and a bed temperature that improves adhesion without causing excessive softness. Store filament in a dry environment or sealed container with desiccant to preserve print quality.
