3D-Fuel Pro PETG Filament | Charcoal Gray | 1.75mm | Made in USA

American-Made PETG. Precision-Manufactured. Print-Ready.

3D-Fuel Pro PETG Charcoal Gray is a premium 3D printing filament manufactured in 3D-Fuel's own production facility in Fargo, North Dakota, with complete control over every step of the process, from raw material to finished spool. Made from 100% virgin PETG resin, it delivers the ideal balance between ease of printing and real-world performance: the approachability of PLA with the strength, temperature resistance, and impact toughness of ABS.

Charcoal Gray is the practical, professional choice — a neutral, refined tone that works across functional parts, enclosures, and display pieces without drawing attention to the color itself. It lets the form and function of your print do the talking. And because 3D-Fuel runs multi-axis laser diameter and ovality measurement in real-time during production, every spool ships with the exact diameter and ovality readings printed right on the box — so you know what you're loading before you print.

Near-zero warpage. Extremely strong layer bonds. Little to no odor during printing. Pro PETG is dialed in, where standard PETG can be finicky.

Note: Pro PETG prints a little hotter than some PETG filaments. See the recommended settings below and dial in from there.

Built for makers who need performance and reliability — perfect for:

• Functional parts, enclosures, brackets, and mechanical components requiring strength beyond PLA
• Outdoor and high-heat applications where standard PLA would soften or fail
• Waterproof and moisture-resistant prints — bottles, containers, and fluid-contact parts
• Structural assemblies, load-bearing brackets, and snap-fit components
• RC car and drone bodies, robotics housings, and protective casings
• Engineering prototypes and concept models where a neutral, professional finish matters
• Any project where near-zero warpage is non-negotiable

Available in 1kg and 4kg spools — choose your spool size when adding to cart.

Printer Compatibility: Compatible with most 1.75mm FDM 3D printers. Tested in-house on MakerBot, LulzBot, FlashForge, and more.
