Filament Spectrum PET-G FX120 1.75mm OBSIDIAN BLACK 0.5kg

Spectrum PET-G FX120 1.75mm OBSIDIAN BLACK 0.5kg (RAL 9017)

Spectrum PET-G FX120 Obsidian Black is a high-performance, semi-flexible filament engineered for advanced technical applications. It combines the durability and chemical resistance of engineering-grade polymers with the adaptability of elastomers, making it ideal for parts that must endure mechanical stress, elevated temperatures (up to 120°C), and even steam sterilization. With Shore hardness 95A and excellent dimensional stability, it prints reliably even on Bowden systems or multi-material setups, bridging the gap between strength and flexibility.

This material is perfect for creating functional components such as chemical-resistant gaskets, shock-absorbing elements, and edge protectors — all with a smooth, high-quality surface finish and minimal stringing.

Key highlights:

• Temperature resistance up to 120°C
• Steam-sterilizable and odorless
• Shore hardness: 95A
• Excellent print speed and surface quality
• Compatible with Bowden and multi-material printers

Typical uses:

• End-use parts requiring energy absorption
