3D printer filament Spectrum PET-G midnight black 3 kg (PETG-mBLACK-3-TF)

Spectrum PET-G midnight black is a 3 kg spool of PET-G filament formulated for FDM/FFF 3D printers. The material combines the mechanical strength and chemical resistance of glycol-modified PET with a finish suitable for visible parts. The filament is provided on a commercial-sized spool and is intended for users who need consistent black prints for functional prototypes, durable components and aesthetic models. Use standard PET-G print profiles and a compatible 3D printer to achieve glossy, dark black results.

Advantages

Spectrum PET-G offers a balance of toughness, dimensional stability and ease of printing compared with many engineering plastics. The midnight black color provides uniform coverage and reduces post-processing for visual parts. The 3 kg spool reduces the need for frequent filament changes in medium- to large-volume printing and supports longer print runs with consistent diameter and extrusion behavior when used with recommended printer settings.

Suitable for

• Functional prototypes and mechanical parts requiring impact resistance
• End-use components and fixtures with aesthetic black finish
• Visual models, concept displays and signage
• Repeated or extended print runs where a larger spool is preferred

Key specifications

• Material: PET-G (glycol-modified PET)
• Net filament weight: 3 kg
• Color: midnight black
• Intended printing technology: FDM / FFF 3D printing
• Finish: glossy dark surface

How to use

Load the Spectrum PET-G midnight black filament onto a compatible FDM/FFF 3D printer spool holder, making sure the filament feeds smoothly and the spool can rotate without obstruction. Set your printer to standard PET-G printing parameters for nozzle temperature, bed temperature and print speed according to your machine and nozzle size. Use a suitable build surface or adhesive to ensure first-layer adhesion; allow adequate cooling and avoid high fan speeds during bridging where strength is required. Monitor the first layers to confirm proper extrusion and bed adhesion before running longer prints.

Usage recommendations

For best results, print with a moderately heated bed, reduced print speed compared to PLA, and appropriate retraction settings to minimize stringing. Store the filament in a dry environment or sealed container with desiccant to preserve print quality over time.
