Filament Spectrum PET-G 1.75 mm — WIZARD CHARCOAL — 1 kg spool

Spectrum PET-G 1.75 mm filament in WIZARD CHARCOAL is a 1 kg spool of black PET-G material designed for FDM/FFF 3D printers accepting 1.75 mm filament. PET-G combines higher toughness and chemical resistance than PLA with easier printing and less warping than ABS, making this filament suitable for functional prototypes, mechanical parts and durable consumer components. The material offers good layer adhesion and moderate flexibility, and prints at a recommended nozzle temperature range of 230–260 °C.

Advantages

This PET-G filament provides improved impact resistance and durability compared with PLA while remaining relatively easy to print. The WIZARD CHARCOAL color delivers consistent black tones with reliable extrusion from a standard 1 kg spool. PET-G shows good chemical and moisture resistance for many applications, strong interlayer bonding for structural parts, and moderate flexibility that reduces brittleness in finished prints. The filament is suitable for extended use where a balance of strength and printability is required.

Suitable for

• Functional prototypes and proof-of-concept models
• Mechanical components, gears and brackets
• Durable consumer parts and housings
• Items requiring good layer adhesion and impact resistance

Key specifications

• Material: PET-G
• Diameter: 1.75 mm (nominal)
• Recommended printing temperature: 230–260 °C
• Spool weight: 1,000 grams
• Color: Black (WIZARD CHARCOAL)

How to use

Load the filament into a compatible 1.75 mm extruder following your printer manufacturer’s instructions. Set the hotend temperature within the recommended 230–260 °C range and adjust print speed, retraction and cooling to suit your machine and part geometry. Use a heated bed or adhesion surface as needed; moderate bed temperatures and a clean, flat build surface improve first-layer adhesion. Ensure the filament is dry before printing to avoid moisture-related defects.

Usage recommendations

Store the spool in a dry, sealed container or with desiccant when not in use to maintain print quality. Fine-tune cooling and retraction settings to reduce stringing while preserving interlayer strength. For structural parts, consider increasing wall thickness and infill density to exploit PET-G’s toughness and adhesion properties.
