Glass-fiber stiffness. Stocked & shipped from our US warehouse.
Rev1 PETG-GF is chopped-glass-fiber-reinforced PETG — extra stiffness and dimensional stability for functional, load-bearing parts, available in Black and White. Stocked and shipped from Auburn Hills, Michigan; made-to-order sizes ship in 1–3 weeks. Run it through a hardened steel nozzle.
Extra stiffness and dimensional stability — without the price jump.
PETG is easy to print, tough, and chemical-resistant. Rev1 PETG-GF adds glass-fiber reinforcement to raise stiffness and lock in dimensional stability at an economical price — a practical, low-warp composite for functional and structural parts that don't need the premium of carbon fiber.
Glass-fiber stiffness — PETG toughness.
A cost-effective composite for stiff, stable parts.
Unfilled PETG is tough but flexible. Rev1 PETG-GF adds glass fiber to boost stiffness and dimensional stability while keeping PETG's chemical and moisture resistance — ideal for brackets, panels, housings, and fixtures where you want rigidity without paying for carbon fiber.
The properties that make it an engineering filament.
Glass-fiber reinforcement raises stiffness well above plain PETG for parts that resist flex.
Improved dimensional stability and low warp for parts that hold their tolerances.
Keeps PETG's toughness — parts absorb impact instead of shattering.
Excellent chemical and moisture resistance for parts used indoors and out.
Prints on any heated-bed printer with a hardened nozzle — no enclosure required.
Glass-fiber stiffness at a lower cost than carbon-fiber grades — great value for functional parts.
Print settings that just work.
Run a touch hotter than plain PETG for strong layer bonding with the glass-fiber fill.
Good first-layer adhesion on a warm bed; a smooth PEI sheet or light glue aids release.
Glass fiber is abrasive — use a hardened-steel or wear-resistant nozzle.
Dry the spool before printing for the best surface finish and to eliminate stringing.
Prints reliably on open-frame, heated-bed machines — no enclosure required.
A slightly larger nozzle flows the filled filament smoothly and boosts part strength.
Glass-fiber PETG for stiff, functional parts.
Stiff, stable, chemical-resistant, and economical — PETG-GF is a go-to for functional and structural parts where you want rigidity without the premium of carbon fiber.
Flat, rigid panels that stay flat.
Low warp keeps large parts true.
Mounting panels, plates, and structural parts benefit from glass-fiber stiffness and improved dimensional stability — large flat parts stay flat instead of warping.
Stiff, economical shop tooling.
Rigid workholding without the CF price.
Assembly jigs, fixtures, and workholding that resist flex and hold their shape — a cost-effective choice for shop-floor tooling made in volume.

Rev1 PETG-GF — common questions.
Do I need a hardened nozzle?
Yes. The glass fiber that stiffens this filament is abrasive and will wear out a standard brass nozzle. Use a hardened-steel or other abrasion-resistant nozzle.
How is PETG-GF different from PETG-CF?
Both reinforce PETG for stiffness. Glass fiber (GF) is stiff and more economical; carbon fiber (CF) is stiffer still with a premium matte-black finish. We'll help you choose based on your part and budget.
Do I have to dry it?
Drying before printing is recommended for the best surface finish and to eliminate stringing. Keep the spool in a dry box between prints.
Do I need an enclosure?
No — PETG-GF prints reliably on open-frame, heated-bed machines. Its low warp helps large parts stay flat without one.
What sizes and colors are available?
Black and White in 1.75 mm, on 1 kg spools. Pick your color in the buy-box; ask us about bulk.
Can Rev1 help me qualify it?
Yes. Tell us the part, loads, and environment and our materials team confirms fit, suggests print settings, and can share the full datasheet.
