3D printer filament Spectrum The Filament ReFill PETG 1.75 mm Midnight Black 1 kg

Spectrum The Filament ReFill PETG 1.75 mm Midnight Black is a 1 kg spool of PETG filament designed for FDM/FFF 3D printers. The material balances mechanical strength and chemical resistance with reliable layer adhesion and lower tendency to warp compared with some other thermoplastics. The filament’s midnight black matte finish is suitable for functional parts, prototypes and end-use components that require durability and a neutral aesthetic.

Advantages

PETG offers a combination of toughness and flexibility that makes it less brittle than PLA while maintaining good printability. This filament provides consistent extrusion from a standard 1.75 mm diameter, produces strong interlayer bonding, and resists moisture and many common chemicals. The mid-range working temperature and packaging in a 1,000 gram spool make it practical for longer print runs and for producing mechanically reliable parts with a uniform black appearance.

Suitable for

• Functional prototypes and mechanical parts
• End-use components exposed to light chemical contact
• Enclosures, brackets and fixtures requiring dimensional stability
• Visual models and parts with a matte black surface finish

Key specifications

• Material: PETG (glycol-modified PET)
• Diameter: 1.75 mm nominal
• Recommended print temperature range: 230–250 °C
• Spool weight: 1,000 grams
• Color: Midnight Black (matte appearance)

How to use

Load the filament into an FDM/FFF 3D printer configured for 1.75 mm filament. Set the nozzle temperature within the recommended 230–250 °C range and adjust print speed, fan and retraction settings according to your printer and part geometry. Use a heated build plate or adhesive surface to improve first-layer adhesion; typical bed temperatures for PETG are higher than for PLA but depend on your printer and build surface. Allow adequate cooling between prints and store the spool in a dry place when not in use to minimize moisture absorption.

Usage recommendations

For best results, perform a small temperature tower and retraction test when switching to this filament or a new spool. Use moderate print speeds and conservative retraction settings to reduce stringing and ensure consistent layer bonding. Dry the filament before printing if it has been exposed to humid conditions.
