Bambu Lab PETG HF Black (33400) is a high-flow PETG filament engineered for the demanding extrusion requirements of Bambu Lab printers. The HF (High Flow) designation means this filament is formulated to extrude smoothly at higher speeds than standard PETG, enabling faster print cycles without sacrificing the surface quality and mechanical properties that make PETG a go-to choice for functional parts. The black colorway (code 33400) is a timeless neutral that suits functional prototypes, engineering parts, and production components requiring a clean, professional finish.

PETG HF offers the hallmark benefits of PETG - good layer adhesion, low warping tendency, light chemical resistance, and a semi-glossy surface finish - with the added advantage of Bambu Lab's high-flow optimization for reduced print times on X1, P1, and A1 series printers. This variant is available in refill (no spool) format, Also available as with spool for the same color. and the full PETG HF range covers Black, Blue, Yellow, White, Red, Green, Gray, and Orange, so you can maintain color consistency across different projects.

Key features

• High Flow (HF) formulation enables faster extrusion speeds for reduced cycle times without print quality loss.
• Excellent layer adhesion and low warping tendency for reliable, warp-free results on large prints.
• Light chemical resistance and moisture tolerance for functional prototypes and end-use parts.
• Semi-glossy surface finish suitable for visible consumer-facing components.
• Available in refill (no spool) format - economical choice for high-volume users with existing spools.
• Full PETG HF color range includes Black, Blue, Yellow, White, Red, Green, Gray, and Orange for consistent multi-project color management.

Compatible with: Bambu Lab X1 series, P1 series, A1 series (AMS and single spool)
