GST3D PETG Filament – Strong, Durable & Easy to Print

GST3D PETG filament is a versatile 3D printing material that combines the ease of printing of PLA with the strength, durability, and chemical resistance of ABS.
It’s an ideal choice for makers and professionals seeking a balance between mechanical performance and printability.

Perfect for functional parts, enclosures, tools, mechanical components, and everyday prints.
PETG offers reliable performance with excellent layer adhesion, minimal warping, and a slightly glossy surface finish.

Key Features

• Excellent impact resistance – stronger than PLA and less brittle than ABS
• Great mechanical properties – strong, tough, and slightly flexible
• Easy to print – minimal warping, excellent layer bonding
• Chemical & moisture resistance – ideal for parts exposed to water, oils, or cleaning agents
• Slightly glossy finish – smooth, professional appearance
• Perfect for functional parts & prototypes – enclosures, brackets, tools, and mechanical components

Technical Specifications

• Filament diameter: 1.75 mm ± 0.02 mm
• Printing temperature: 220 – 260 °C
• Bed temperature: 60 – 90 °C (heated bed recommended for best adhesion)
• Recommended nozzle diameter: ≥ 0.4 mm
• Recommended print speed: 40 – 150 mm/s
• Density: ~1.27 g/cm³
• Spool net weight: 1 kg
• Surface finish: Slightly glossy, smooth

Recommendations for Best Results

• Use a heated bed (70–80 °C) and apply an adhesive (glue stick, PEI sheet, or textured surface) for optimal adhesion.
• Enable an enclosure or draft shield for large prints to prevent layer separation.
• Reduce part cooling fan speed (30–50%) to improve inter-layer bonding.
• Store filament in a dry box or sealed bag with desiccant to avoid moisture absorption.
• For structural parts, use higher wall thickness and infill (30–50%) for maximum durability.
