PETG Filament 1.75mm 3kg bulk spool is large‑capacity engineering‑grade 3D printing filament. It maintains standard PETG’s excellent impact toughness, water resistance and reliable layer adhesion. The 3kg large spool reduces frequent spool replacement, improves work efficiency and lowers unit material cost, perfectly suited for workshop batch production and high‑volume printing on mainstream FDM 3D printers.

Product Detail

Product Overview

PETG Filament 3kg Bulk Spool is high‑capacity FDM 3D printing consumable for commercial and workshop usage. Each large spool contains 3kg filament with standard 1.75mm diameter. It inherits all core advantages of conventional PETG material including good toughness, impact resistance and moisture resistance. Large‑volume spool minimizes frequent spool changing interruption, increases continuous printing time and reduces per‑unit cost for high‑volume batch printing tasks.

Key Features

3kg net weight bulk large spool, standard 1.75mm diameter
Consistent material performance same as 1kg spool PETG
Outstanding impact toughness and strong inter‑layer adhesion
Good water resistance and moderate chemical tolerance
Strict diameter tolerance for long‑run stable extrusion
Reduce spool swap frequency for continuous printing
Cost‑effective for workshop and mass‑print scenarios
Neat spool winding prevents tangling during long‑time printing
Compatible with most desktop and industrial FDM 3D printers

Main Applications

Workshop high‑volume batch 3D printing production
Mass‑produced functional prototypes and assembly parts
Education laboratory heavy‑use continuous printing projects
Small‑batch custom manufacturing and commercial printing service
Durable functional components requiring large material consumption

Printing Suggestions

Recommended nozzle temperature: 230‑250℃ Recommended bed temperature: 70‑90℃ Suggested print speed: 40‑80mm/s PETG is highly hygroscopic. Fully dry filament before printing to avoid bubbles, stringing and weak layer bonding. Ensure printer spool holder fits 3kg large‑size spool. Enclosed printer environment is recommended for better dimensional stability.

Package & Storage

Net Weight: 3kg per bulk spool Packaging: Vacuum‑sealed packing with desiccant inside Store in cool, dry, low‑humidity environment. Reseal package tightly after opening to prevent moisture absorption.
