The Filament 3D filament, PETG, 1,75mm, 1000g, TF-24017, basalt grey from Spectrum is engineered for makers who want durability and reliability without sacrificing print simplicity. This PETG formulation blends strong layer adhesion with easy printing, delivering functional parts that look as good as they perform.

Why PETG makes sense for your projects: it sits between the ease of PLA and the toughness of ABS, offering solid impact resistance, good chemical compatibility, and superior layer bonding. The basalt grey color gives your prints a professional, semi-metallic finish that hides minor layer imperfections and looks great on enclosures, mechanical parts, and tool-ready components alike. With a 1.75 mm diameter and a full 1 kg spool, you’ll enjoy smooth extrusion, fewer jams, and enough material for long print sessions or bulk prototyping runs.

Spectrum’s PETG is designed for consistency. You’ll notice steady extrusion across the spool and reliable performance from first layer to final pass, which translates to fewer print retries and more productive sessions. The basalt grey hue is not just about aesthetics—it's a versatile shade that pairs well with other materials and reduces visual wear on parts that see regular use.

Key benefits in practice

  • Strong, impact-resistant parts: PETG’s toughness makes functional components, housings, and brackets durable enough for daily use and light-to-medium duty environments.
  • Excellent layer adhesion: Consistent bonding between layers leads to sturdier prints with less delamination, ideal for living hinges, snapping joints, and mechanical prototypes.
  • Low warping, easy bed adhesion: Print beds stay level with minimal corner lifting, enabling reliable first-layer success on common heated beds.
  • Premium basalt grey finish: A sophisticated color that maintains a professional look for parts destined for display or field use.
  • Long-run practicality: 1 kg spool supports extended projects, making it suitable for workshops, classrooms, and solo makers alike.

Printing at a glance

Typical printing guidance for this PETG filament: start with a nozzle temperature in the 235–245°C range and a heated bed at about 70–80°C. Print speeds around 40–60 mm/s strike a balance between accuracy and efficiency, while a moderate fan helps with bridging without cooling the layers too aggressively. Use a reliable build surface such as PEI, glass, or a well-prepped surface, and consider a light adhesive if your printer tends to lift corners on large parts. Keep the filament dry when not in use to prevent moisture-related print defects and fogging of the surface.

Who should use this filament

  • Engineers and designers prototyping mechanical parts, housings, or brackets that need real-world durability.
  • Educators and students working on projects that demand robust, readily printable materials with a premium finish.
  • Hobbyists building functional tools, enclosures for electronics, or display-ready components with a sleek basalt grey aesthetic.
  • Production and workshop environments seeking consistent spools that minimize downtime and reprints.

Why choose Spectrum PETG basalt grey

Spectrum brings a track record of color consistency, material reliability, and print-ready performance. This PETG filament is formulated to deliver dependable extrusion, steady dimensional stability, and a finish that looks refined on a wide range of parts. The TF-24017 basalt grey variant is purpose-built for projects where a balance of strength, clarity of detail, and a mature color helps your work stand out—without requiring complex post-processing steps or extreme printing conditions.

Practical tips for best results: always calibrate your printer’s extrusion multiplier for PETG, keep the nozzle clean between sessions, and store the spool in a dry environment to preserve performance on the next project. With The Filament 3D PETG basalt grey, you’re equipped to turn ideas into prototypes and production-ready parts with confidence—and a finish you’ll be proud to show off.
