What is UltraDry Filament?

UltraDry Filament is a next‑generation 3D printing material produced using PETGUSA’s DryFusion™ process and sealed to meet the UltraDry™ Certification Standard. It arrives pre‑dried, moisture‑proof, and ready to print, eliminating the need for filament dryers, ovens, or storage boxes.

Unlike traditional filament, UltraDry Filament maintains near‑zero moisture content from production to your printer — ensuring stronger parts, smoother extrusion, and dramatically more consistent results.

Moisture is the #1 cause of print failures in PETG, PLA, ABS, and other hygroscopic materials.
Wet filament leads to:
stringing and oozing
brittle parts
inconsistent layer bonding
surface pitting
dimensional inaccuracy
clogged nozzles

UltraDry Filament solves this at the source — before moisture ever enters the material.

DryFusion™ Processing

A proprietary formulation and thermal process that removes bound moisture and stabilizes the polymer.

UltraDry™ Certification

A measurable moisture‑content threshold that no traditional filament meets out of the box.

Moisture‑Proof Packaging

Industrial‑grade barrier film + humidity indicator + vacuum seal.

Zero‑Exposure Manufacturing

Produced, cooled, and spooled in a controlled environment to prevent reabsorption.

Ready‑to‑Print Guarantee

No drying. No prep. No guesswork.

Zero drying required — print immediately

Stronger layer adhesion

Smoother extrusion and flow

Reduced stringing and blobs

More accurate dimensions

Better bridging and overhangs

Cleaner surfaces with fewer artifacts

Longer spool shelf life

Industrial‑grade consistency
