3D-Fuel Pro PETG Filament | Clearly Natural | 1.75mm | Made in USA

American-Made PETG. Precision-Manufactured. Light Passes Right Through.

3D-Fuel Pro PETG Clearly Natural 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.

What makes Clearly Natural stand out is its optical properties. Prints come out nearly transparent with exceptional light transmission — allowing light to pass through the finished part in ways that no opaque filament can match. Layer height and print settings directly influence how your parts transmit light, giving you creative control over the final translucency effect. Thinner layers and slower speeds produce the clearest results; thicker layers create a more diffused, frosted effect.

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

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

Where light transmission opens up new creative possibilities — perfect for:

• Lampshades, light diffusers, and LED channel covers
• Decorative panels, window inserts, and architectural light features
• Scientific and laboratory components where optical clarity matters
• Display cases, product stands, and retail fixtures
• Artistic prints and sculptures where light interaction is part of the design
• Functional parts — containers, lids, and fluid-contact components where visibility is needed
• Any application where PETG strength is required in a near-transparent form

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